INTRODUCTION WHAT IS PIPING?


WHAT IS PIPING?

PIPING is a powerful addition to Autodesk’s popular AutoCAD drafting package. The program architecture takes advantage of the latest AutoCAD technology to enable you to produce intelligent, three-dimensional production models under demanding deadline constraints. If you are a new user of Bentley AutoPLANT PIPING, you will soon discover that PIPING provides a true three-dimensional work environment. Objects can be viewed from any perspective, and users can toggle between various display modes almost instantaneously, without creating duplicate objects in the drawing or experiencing a “lag” in redraw time. What’s more, the underlying data is more powerful than ever. Component and drawing control data is dynamically linked to an external project database. The database information can be used to generate reports, or to globally manipulate and revise the descriptive component data.

INTRODUCTION ABOUT THIS TUTORIAL


ABOUT THIS TUTORIAL

The model constructed in this tutorial is not intended to be a working piping arrangement. Instead, the focus is on building a model that demonstrates the major features of the PIPING application. As the model is constructed, you will learn various techniques that can be used to place and connect components. The finished tutorial model is shown below.

This tutorial also emphasizes the use of PIPING’s Drawing Production utilities to place annotation, dimensions, Bill of Materials, and Sections in Paper Space as shown below.

INTRODUCTION ABOUT THIS TUTORIAL


COMPONENT PLACEMENT BASICS

Chapter 3 of this tutorial introduces the PIPING interface, while Chapter 4 introduces the basic placement procedures. These exercises are provided to help you get comfortable with the full range of placement options. Exercises are provided that describe connecting components, placing components with respect to a reference point, toggling the insertion point, changing the reference point, aligning components, etc. By the end of this section, you should be familiar with the placement interface and be able to quickly place a component anywhere in your model with precision.

Note If you want more information on the range of connection and placement options, refer to the Getting Started section of the on-line help.

MODEL CONSTRUCTION

The bulk of this tutorial focuses on the construction of a simple piping model. Separate chapters are provided on project-setup, building the model, working with model data, annotating and dimensioning the model, and producing reports. At the end of the tutorial, you will have constructed a sample piping model, obtained a solid working knowledge of the program, and learned how to apply these techniques to create your own models.

PRE-START CHECKLIST

OTHER FEATURES

PROJECT DATABASE SERVER SOFTWARE SUPPORT

One of the primary capabilities of Bentley Plant applications is support for powerful databases such as SQL Server and Oracle. Previously, only MS Access was supported and the user had to manage their project using manual procedures. There are three modes of operation that you can choose from for a project.

! Standalone mode: single drawing, no project database. Suitable for a one-off drawing or a small project.

! Distributed mode: project database, with individual model MDB files. This mode closely resembles the capabilities provided in AutoPLANT 3D v2.01 applications. Distributed mode



is intended for small/medium sized projects where the user wants to continue to run MS Access or MSDE for the primary database while retaining the benefits of a managed project.

! Central mode: all data stored in central project database. Requires MSDE, Oracle, or SQL Server.

Note Central Mode and/or Oracle & SQL Server is an additional cost item

The following databases can be used with AutoPLANT 2004.

! Oracle 8.17, 8.16, and 9i.

! SQL Server 7.0 and 2000

! MSDE 2000

! Microsoft Access 97 (Specs only) and 2000

INTEGRATION WITH AUTOPLANT P&IW APPLICATIONS

Bentley AutoPLANT 3D Plant Design (PDW) applications use the same project structure as Bentley Process and Instrumentation (P&IW) applications with both 2D and 3D data in the same database. There are some tables used exclusively by these product groups, and some that are shared. Shared tables include the tag register, document register and process line list.

Note that by using this strategy, you can have a project running P&IW applications, PDW applications, or both. It is not a requirement to have Bentley P&IW applications installed to use the project environment.

If both application sets are used, the 3D user will see a full list of line numbers to select from when routing piping. When placing equipment, they will be able to select equipment tags from those that were previously placed on a Bentley AutoPLANT P&ID, or otherwise entered into the project database.

If the user is only responsible for the detailed design phase of a project, P&IW applications such as Data Manager and Datasheets can still be used in conjunction with the PDW data. Line list reports or equipment data sheets can be generated from the data entered by the 3D environment.

There are additional 2D/3D tools such as the ability to browse the P&ID from within a 3D application, set the current spec and size from a component on the P&ID, etc.



PRODUCTIVITY

PIPING’s emphasis is on producing finished 3D models. Drawing production tools are provided to set up work areas and views. These enable you to manage multiple drawings developed for a particular project and generate production drawings from them. Production drawings can be output, reports generated, and drawings created with other AutoPLANT applications, such as EQUIPMENT or STRUCTURAL can be xreferenced in to complete the model.

A variety of features are available to automate most repetitive drafting tasks. Extensive use of PIPING's utilities automate processes such as conversion between drawing modes, generation of Bill of Materials, routing centerline paths, automatic placement of pipe, etc. Our goal is to automate the processes that formerly required intensive user interaction, thereby saving you time while ensuring accurate, clean models. Managers responsible for meeting tight production deadlines will appreciate this important design philosophy.

TRUE 3D DESIGN

When our developers began work on PIPING, much of the emphasis was placed on creating clean three-dimensional models. It was also a requirement that the file size be minimized, and that views be available to support a variety of display modes without the added baggage of creating duplicate copies of components. The result of our efforts is a true three-dimensional work environment that does not sacrifice speed or drawing size to achieve its goal. Gone are the days of being forced to visualize 3D objects in 2D space. Of course, the model can always be displayed in 2D mode and optimized for plotting, but we are sure that you will find connecting components and routing pipe lines much easier using the 3D methodology.



COMPONENT DISPLAY AND REPRESENTATIONS

PIPING is an open-ended system, which enables you to customize almost any aspect of the component placement process. PIPING components are constructed parametrically by executing instructions in external Basic scripts. These scripts contain instructions to read the external specification database and extract the parametric dimensions required to draw the component in 3D, Double Line, or Single Line drawing modes, and to write its external project database record. With a general understanding of BasicScript syntax and terminology, you should be able to create/modify almost any aspect of the component placement process.

Note The Basic Language Reference help file may be launched via the Bentley > Plant > Tools group in your Windows Start menu. It provides help on the Bentley AutoPLANT Basic Language Extensions provided to customize the system, as well as standard Basic Language element help.

PIPING components are constructed from a group of Custom Objects. For example, a piece of piping is created from a cylinder, while a flanged ball valve is created from two cylinders for the flanges, two cones, and a sphere. These custom objects have four inherent display modes, which enable you to almost instantaneously switch between display modes.

In addition, the PIPING application provides a set of representation commands that enable you to generate and display single line, double-line, and 3D representations of specific components in a piping line, or complete lines in the same model.



INTELLIGENT SELECTION

PIPING models are not merely drawings. As the model is created, a project database is also maintained, which contains a record for each component placed in the model as well as relationships between components and specific project properties in the model. A component’s data can be edited at any time during a drawing session.

Many PIPING functions enable you to apply the function to a selection set of components. PIPING’s selection tool enables you to define a selection set by querying the project database as a whole, which will select component records from all drawings based on the value of a project object (e.g., LineNumber), or to query based on drawing attributes (e.g., color, layer). After a selection set of components is created, you can globally revise values, change line numbers, enter unique descriptions, etc. This is particularly useful when updating drawings due to design changes.



SPECIFICATION-DRIVEN

PIPING provides sample database catalogs of tens of thousands of components from which manufacturer-specific specifications may be produced. The Specification Generator program enables you to build and customize the database specifications used with particular projects or clients. Each specification is a subset of a catalog and is stored in its own directory. Specifications can also be edited or modified to suit unique requirements, and any number of specifications can be created.

The ability to select and apply one or more specifications consistently throughout one or more drawings or projects is why we call PIPING a specification-driven application. Because PIPING components are placed according to defined specifications, they are not merely drawing blocks. Instead, the components are built parametrically, and therefore have a high degree of intelligence.

To expedite the drawing process, sample specifications are included. These specifications are available in Imperial, Metric, and/or Mixed-Metric versions. A brief description of some of the sample specs provided is given below:

! Carbon Steel: A sample carbon steel specification, based on 150-pound ANSI pressure classification (Imperial: CS150, Metric: MCS150, and Mixed Metric: MMCS150).

! Stainless Steel: A sample stainless steel specification (Imperial: SS150, Metric: MSS150, and Mixed Metric: MMSS150).

! Ductile Iron: The Ductile Iron Pipe module provides a set of components, which are typically used for water/wastewater applications. A sample ductile iron specification (Imperial: Ductile, Metric: MDUCT, and Mixed Metric: MMDUCT).

! Victaulic: The Victaulic module provides a set of components, which are typically used in commercial building piping. A sample Victaulic specification (Imperial: Victalic, Metric: MVICT, and Mixed Metric: MMVICT).

! High Purity: The High Purity module provides a set of components, which are typically used in HiPurity, Food/Bev, Pharmaceutical, Dairy, Breweries, etc. A sample High Purity specification (Imperial: TriClove, Metric: MTRIC, Mixed Metric: MMTric).

! Lined Pipe: A sample Resistoflex (RSF) specification (Imperial: RSF, Metric: MRSF, Mixed Metric: MMRSF).

! Cable Tray: The Cable Tray module provides a standard set of cable tray components used in most industries. A sample Cable Tray specification (Imperial: CableT, Metric: MCableT, and Mixed Metric: MMCableT).



! Conduit: The Conduit module provides a set of thin wall tubing components, which typically contains electrical wires and are used by most industries. A sample Conduit specification (Imperial:Conduit, Metric: MCond, Mixed Metric: MMCond).

! HVAC: The HVAC module provides a set of components for Heating/Ventilating/Air Conditioning. Typically, this Ductwork is used by all industries where the plant is inside a building, including Food/Beverage, Pharmaceutical, Dairy, Breweries, etc. A sample HVAC specification (Imperial: HVAC, Metric: MHVAC, Mixed Metric: MMHVAC).

! Tubing: The Tubing module provides a set of components, including small bore tubing used for instrumentation lines in many industries These components are typically used in the pharmaceutical industry, and also in mechanical design applications (pump manufacturers, etc). A sample Tubing specification (Imperial: Swagelok, Metric: MSwglok, Mixed Metric: MMSwglok).

PIPING’s specification-related features include a default component switch, which enables you to force the system to utilize the spec record that you have defined as the default for a specific component size.

Note Refer to the Spec Generator’s on-line help system for more information on specification-related features and functions.

PIPING uses the Microsoft ACCESS (*.MDB) versions of the specs as the default.

FLEXIBLE PLACEMENT CAPABILITIES

Components can be placed with greater ease than ever before. You can automatically attach a component to the run end of the previous component using the “fitting-to-fitting” method, place a component a known distance from a reference point, align a component to the centerlines of two existing components, automatically attach a component to the intersection of a polyline, insert a component into an existing pipe segment, toggle the insertion point on a component, and change the reference point, elevation, etc. In short, the placement tools enable you to quickly place a component anywhere in the model with precision.

Note Chapter 4, Component Placement Basics provides an overview of component insertion techniques.



AUTOPLANT’S REPORT WRITER MODULE

The AutoPLANT Report Writer module provides a means to generate a wide range of reports on the data contained in the current drawing, or across a range of project drawings. AutoPLANT makes extensive use of the Crystal Reports™ run-time engine to process data in the external project database. Two functions are provided with the report module. First, the Bill of Materials function uses the module to generate and place reports on the CAD drawing. Second, the Report Generator function uses the module to generate external reports. You can customize any of these reports or create your own.

The Bill of Materials function generates reports for placement on a drawing. You can customize any of these reports, or create your own. For instance, it is now a simple task to filter the selection set of components that will be included in a report based on one or more criteria across one or more project drawings. The Bill of Materials module shown below provides a means to generate a wide range of external reports on the data contained in the current model, or across a range of project models.



The AutoPLANT Report Generator function generates fully customizable external reports. The dialog that appears when you execute this function is shown below.

CENTERLINE ROUTERS

The Piping Tools > Centerline Routers menu provides commands to construct the geometry of a piping line. Elevation and coordinate data are stored on the line and are applied to components placed on them. You can also associate intelligence, including: size, spec, line number, insulation thickness, etc. with the line so that these settings are assigned to any component placed on the line. The Centerline Routing tools are often the easiest method of defining an entire pipe run, or all runs in a given model.



PROGRAM ARCHITECTURE - CUSTOMIZATION

AutoPLANT applications take full advantage of the latest AutoCAD ARX technology. An ARX application is a dynamic link library (DLL). The PIPING application is supported by a series of ARX applications. Within these ARX applications, AutoPLANT has implemented a BasicScript engine.

The PIPING architecture was designed with your customization needs in mind. In addition to the standard BasicScript function and command set, Bentley has developed a set of BasicScript API Extensions to facilitate the creation of component drawing scripts and manipulation functions. These extensions consist of a set of Basic data types, commands, and functions specifically designed for the creation of AutoPLANT components. These functions, combined with the standard BasicScript macro language, provide a full-featured environment for script development and customization of the PIPING application.

All PIPING components, and most dialogs, are defined in open BasicScript files for easy modification. The system architecture enables a user with a solid foundation in the Visual Basic for Applications programming language to modify almost any aspect of the component placement process, or to create new components or add new functions to the system.

Note The Basic Language Reference help file may be launched via the Bentley > Plant > Tools program group in your Windows Start menu.

SUPPLEMENTAL APPLICATIONS

AutoPLANT software is shipped with a set of supplemental applications. These utilities are provided in the main AutoPLANT 3D menu and toolbar as shown below. The top part of the menu contains options to launch the primary AutoPLANT applications, while the remainder of the menu provides access to the most commonly used supplemental applications. Options that appear grayed-out in the menu have not been installed.

AutoPLANT Plant Design Toolbar

AutoPLANT 3D Men

Hint Directly launch all of these applications (except Import/Export) from the Windows Start menu by selecting the start icon from the Bentley > Plant > Tools or Project Tools groups.



A brief description of each of these applications is provided in the following table. A more detailed explanation of each application is provided in Chapter 9, Supplemental Applications at the end of this tutorial. Each of these supplemental applications has its own associated context-sensitive help file, which can be launched from the application. Refer to the application help file for a detailed explanation of every available feature and function.

Import/Export

Import/Export is intended to facilitate transfer of CAD data between AutoPLANT and other CAD/CAE software. The transfer is accomplished using Bentley’s Plant Design (PXF) data format, which can either be generated or read by AutoPLANT. AutoPLANT also supports output to a Piping Component Format (PCF) for input to Alias Limited’s ISOGEN software.

Explorer

EXPLORER must be purchased separately. It is an interactive 3D viewer for models and sets of models that interact with these at a guaranteed frame rate. It supports multiple formats, as well as its own native file formats. Navigation and view controls enable the most complex model to be explored with ease.

Explorer ID

EXPLORER ID must be purchased separately. The Explorer Interference Detection add-on, is designed to help you manage clash tests and leave an audit trail of clashes throughout the life of the project. It runs within the EXPLORER interface.

Project Administrator

AutoPLANT may operate in three primary project modes: Standalone, Central, or Distributed. These modes determine the manner in which model data is stored and also may limit access to specific functionality in the application based on this selection. The Project Administrator enables you to create and manage project data and drawing/model defaults and settings. The Project Administrator is the tool for modifying these files and creating saved sets of configuration definitions that can be applied to a particular project.

Class Editor

The Class Editor provides a single source for the manipulation of AutoPLANT PIPING and ISOMETRICS modules, components, and their associated configuration files on a project-by-project basis.

Script Editor

The Script Editor provides an intuitive user interface to create/customize AutoPLANT Basic drawing scripts and functions. Context-sensitive help is provided to almost every standard Basic and AutoPLANT Basic API Extension command, function, data type, etc.

Dialog Editor

The Dialog Editor provides an intuitive graphical user interface to create/customize AutoPLANT-compatible Basic dialogs that may be used in your Basic scripts and functions. The BasicScript statements that construct the dialog instance may be inserted directly into custom scripts created with the Bentley Script Editor.

Specification Generator

The Specification Generator is provided to enable you to create/modify the external drawing database specifications. AutoPLANT provides Imperial, Metric, and Mixed Metric catalogs, which contain tens of thousands of components from which your project-specific specifications can be generated.

NOTE: This application can only be launched from the Windows Start menu.

PROJECT CREATION AND PROGRAM START PROJECT MODES


PROJECT MODES

AutoPLANT enables you to work in one of three project modes. The project mode is determined when you create a project. These modes control how your drawing data is managed. It also may limit some of the application functionality available.

STANDALONE MODE

This project type may be created using MS Access as the database provider only. It essentially treats each drawing created in this manner as a standalone project. Each drawing will have its own associated drawing database (.MDB), with all drawing data stored therein. This is a limited operating mode and will not allow you to perform multiple drawing selections when using AutoPLANT functions.

DISTRIBUTED MODE

This project type may be created using either MSDE, MS Access, SQL Server, or Oracle as the database provider. Each drawing created in this manner will be associated with the selected project and have its own drawing database (.MDB). All relational project data will be stored in the project database.

Note: You must have a Project Server license in order to create project's with an Oracle or SQL Server project database. You may create MSDE or MS Access projects without this authorization.

CENTRAL MODE

This project type may be created using MSDE, SQL Server, or Oracle as the database provider. Each drawing created in this manner will be associated with the selected project and have all of its drawing and relational project data stored in the project database.

Note: You must have a Project Server license in order to create project's with an Oracle or SQL Server project database. You may create MSDE or MS Access projects without this authorization.

PROJECT CREATION AND PROGRAM START PROJECT ADMINISTRATOR


PROJECT ADMINISTRATOR

The Project Administrator application is the primary application for managing AutoPLANT projects. This application may be launched from the AutoPLANT 3D menu while in AutoCAD, or via the Bentley > Plant > Project Tools folder in your Windows Start menu.

Hint A separate guide, Project Administrator’s Guide for AutoPLANT is provided with your software. This document describes project setup and configuration in detail. It is provided in Adobe Acrobat PDF format and may be launched via the Bentley > Plant > Tutorials > Project Administrator’s Guide selection in your Windows Start menu. You must have Adobe Acrobat Reader v4.0 or later installed to view/print this document.

CREATING A NEW PROJECT

For this Tutorial, you will create a sample project on your local drive named IMPERIAL_TUTOR {METRIC_TUTOR}.

> TO CREATE A NEW PROJECT

1. Select Project Administrator from the Bentley > Plant > Project Tools folder in your Windows Start menu. The Project Administrator displays as shown in the following figure.



2. The navigation tree in the left pane is where you access all of your project properties. If you click on the + button to the left of the ..\Bentley Plant Projects node, you will notice that it expands to display three sample project nodes below it as shown above. Clicking on or expanding an individual project node will prompt you to login to that project and will then display its child nodes, which are the property pages for that project.

Note If you are an experienced AutoPLANT user, these properties may be familiar, as they include the configuration settings that were available in prior releases of the software. These configuration settings are now part of the project definition. Tools are provided in the Project Administrator to convert your old v2.01 configurations into the new Bentley Plant project format.

3. The ..\Bentley Plant Projects node in the navigation tree is called a project root folder. This is the directory where the system has created the AT_PROJ.DBF file, which contains a record for every project created under that project root. You may have as many project root directories as you would like, and also as many projects under each root as you would like. In this section, you will define a directory on your local drive as a new project root, then create a new project under that root project directory.

4. Select File > Add Root to display the Browse for Folder dialog. In order for this option to be available in the File menu, you must have something highlighted on the primary root level of the navigation tree (i.e., PA will not let you create a project root directory under an project directory.

5. Click on your local C:\ in the dialog then press the New Folder button. Notice that an editable folder was created on your C:\ drive. Type TutorProject and press Enter to name the folder, then press OK. Notice that the new project root folder C:\TutorProject now appears in the navigation tree on the primary node level as shown in the following figure.

6. The Project Administrator provides a wizard driven interface to create new AutoPLANT projects. The New Project Wizard displays a series of dialogs that walk you step-by-step through the process of creating a new project. The dialogs presented by the wizard depend on the method used to create the project. For example, if you are creating a project from an existing project, the wizard’s Data and Documents dialog will display to enable you to specify how the data and documents in the source project are copied into the destination project. If you are creating a new empty project, you will not be prompted with this dialog, as the wizard recognizes that there are no data and documents to copy.



7. In this example, you will create a new project under your C:\TutorProject root. Select the C:\TutorProject node in the navigation tree. Right-click on this node to display the context menu shown below.

8. Select New Project from the context menu to launch the wizard. You could have also selected File > New Project after selecting the project root to launch the wizard.

9. The first page of the wizard prompts for the Provider Type as shown in the following figure. This selection is used to create the new project using the provided base database structures. Access, MSDE, SQL Server, and Oracle database types are supported. Select the Access provider type as shown in the following figure, then press Next.



10. The Base Template and 3D Settings dialog displays as shown in the following figure. This dialog enables you to assign the project's database format and structures as described below.

NAME DESCRIPTION

Base Schematic Project Template

This selection defines the standards from which the project will be built. The Standard Base Project selection will copy data from the provided Base project to create your new project. This project was installed in your ..\Plant\Base directory.

Units This selection defines the 3D configuration that will be copied into the new project. A configuration consists of a set of files that define the drawing/model defaults and settings. These include the units, specs, drawing database format, borders, drawing templates, module and component options, etc. These configurations were installed in your ..\Plant\Configs directory.

Project Mode The Use Central Project Mode check box will only be available if you selected an SQL Server or Oracle database provider on the wizard's Provider Type dialog. Otherwise, this selection will be disabled and the Distributed project mode will automatically be implemented.

11. Select Standard Base Project and Imperial {Metric} as shown in the previous figure, then press Next.

Note Throughout this tutorial imperial input is provided with its metric equivalent enclosed in brackets { }. Please be sure to enter the appropriate input based on the project type you selected above.



12. The New Project Paths dialog displays as shown below. This allows you to define paths for specific project information. You can edit a field directly by clicking in it and modifying the path location.

13. Accept the default path locations and press Next to continue.

14. The Details dialog displays as shown below.

15. Type IMPERIAL_TUTOR {METRIC_TUTOR} in the Project Name field, and Imperial {Metric} Tutorial Project in the Project Description field as shown above. Enter any desired values in the remaining fields to complete the project details then press Finish to create the project.



16. The Login dialog displays as shown below.

17. Enter the User Name and Password that was given to you by your Project Administrator then enable the Save Password check box and press OK. Enabling the check box instructs the system not to prompt you with the Login dialog for the remainder of your session.

Note If this is the first time you are running this application and your Project Administrator has not provided you with this information, you can simply enter Supervisor for both the User Name and Password to login to the project until such time as your user information is configured.

18. When the process is complete, the new project folder will appear under the TutorProject root project folder. Press the + button to expand the project as shown below.

19. A record for this project has been added to the root project’s database, AT_PROJ.DBF, which resides in the project root directory.



IMPORTING DRAWINGS FROM ANOTHER PROJECT

The Project Administrator provides two wizards to facilitate the transfer of drawings between projects. There may be instances where you want to send a number of drawings from a particular project for someone at another location to either review or work on. The Project Export and Project Import Wizards are provided to accomplish this task.

The Project Export Wizard enables you to select one or more documents (including all) from a project and create an export package, which may then be imported into another existing project using the Project Import Wizard. All of the information needed for the documents to exist in another project will be included in the export package. In addition, when the package is created, you can specify whether you want to export the documents for modification or only for review. This selection determines whether or not the user importing the package will be able to modify the documents, or simply open them as READ-ONLY documents.

Note Imperial and Metric export packages have been provided with your installation that contain drawings required to complete this tutorial as well as the AutoPLANT ISOMETRICS tutorial. If you have already completed the AutoPLANT ISOMETRICS Tutorial and created the tutorial project and imported the Export Package containing the Tutorial drawings, you can skip to the Starting PIPING section later in this chapter.

> TO IMPORT AN EXPORT PACKAGE INTO THE TUTORIAL PROJECT

1. Select Tools > Project Import Wizard from the Project Administrator menu to display the wizard introduction dialog shown below.

2. Press Next to continue.



3. The next dialog prompts you to select the export package location. Press the Browse button to the right of this field, then navigate to and select the Exportpackage.zip file in your local ..\Bentley\Plant 2004\tutorial\imperial {metric} directory and press Open.


5. The Export process log dialog displays as shown below. This dialog will display the log file generated when this export package was initially created. This enables you to review if any errors occurred when the package was created before you import it into your project.




7. The Target project selection dialog displays as shown below. Press the Select Project button then select your tutorial project from the Open Project dialog and press OK. Login to the system when prompted.

8. Information on the selected project will appear as shown above. Press Next to continue.

9. The Specify target location for project documents dialog displays as shown below. The import wizard stores the original document directory in the export package (similar to creating a zip file and saving the directory information). When it extracts the documents, it uses this path. The documents in this export package were originally created in the ..\TUTORIAL directory. In order to extract these documents into a ..\TUTORIAL sub-directory under your main project directory, press the Browse button next to the field, then navigate to and select your main project directory (i.e., ..\TutorProject\IMPERIAL_TUTOR {..\TutorProject\METRIC_TUTOR}). Next, you will manually create a ..\TUTORIAL sub-directory in the selected project directory. This directory will be the target location for the imported documents as shown below.

Note By default, the wizard will assign the first target location defined to all of the documents in the list, You can manually set a path for a document by pressing the Browse button in the Target Location field for that document.



10. Press Finish. You will be prompted to Login to the target project, then the wizard will begin importing the export package. A message dialog will display when the process is complete. Press OK. Press Yes to delete the temporary export package folder. Close the import log file and Exit the Project Administrator application.

PROJECT CREATION AND PROGRAM START CHAPTER REVIEW


CHAPTER REVIEW

This chapter introduced the Project Administrator application, which is the central location for creating and managing projects. You learned how to create a new project and how documents are transferred between projects with the Project Import and Export wizards.

A separate guide, Project Administrator’s Guide for AutoPLANT is provided with your software that describes project setup and configuration in detail. This document is provided in Adobe Acrobat PDF format and may be launched via the Bentley > Plant > Tutorials > Project Administrators’ Guide selection in your Windows Start menu. You must have Adobe Acrobat Reader v4.0 or later installed to view/print this document.

This chapter also described the procedure to launch AutoPLANT Plant Design and start the PIPING application.

WHAT’S NEXT

Chapter 3 provides a general tour of the PIPING application interface. You will learn how to access the tools that enable you to define the various variables and setting used to create models. In particular, the Drawing Preferences and Project Preferences dialogs are covered.


TOUR OF THE INTERFACE

This chapter provides a brief tour of the PIPING interface, and describes the primary tools used to modify drawing, component, and project preferences.

TOUR OF THE INTERFACE TOOLBARS


TOOLBARS

Take some time to familiarize yourself with the layout of the commands and functions in the PIPING interface. After initial startup, you should load at least four of the PIPING toolbars. These provide the quickest access to component placement commands and functions. The toolbars can be “docked” along the perimeter of the drawing area as shown in the following figure, or left “floating.”

1. Select Piping > Toolbars > Piping Components Main.

2. Select Piping > Toolbars > Piping Functions Main.

3. Select Piping > Toolbars > Direction Aids.

4. Select Piping > Toolbars > Responses.

5. Experiment with the placement of these toolbars, as you will be accessing them frequently during the tutorial drawing sessions. In the example above, the Piping Component and Function toolbars were docked to the left of the drawing area, while the Direction Aids and Responses toolbars were docked along the bottom of the drawing area. Toolbars will display in the same location the next time you start PIPING.

The size of the toolbar icons may also be customized. Toggle the display of large or small buttons according to your preference by right-clicking on any button in a toolbar, then selecting Customize from the pop-up menu. When AutoCAD’s Toolbars dialog appears, enable/disable the Large

TOUR OF THE INTERFACE TOOLBARS


buttons option as desired, then press Close. Small buttons will provide a larger drawing area to work in unless you are using dual monitors.

Hint PIPING stores each user’s preferences separately in their local ACAD.INI file. If you are running on a network, you do not need to worry about establishing display preferences that would interfere with other user settings.

Several toolbar selections contain “fly-outs,” which are denoted by the small black triangle in the lower right-hand corner of the toolbar button. Fly-outs are the equivalent of cascading menus; however, they provide the additional benefit of displaying the most recent selection as the default. This technique enables the program to automatically display the most recent selection made from a toolbar.

Note If a button has a triangle in the bottom right corner, it means that it contains “fly-outs.” Once an item is selected from a fly-out, it becomes the default button at that location in the toolbar for the remainder of the drawing session.

Hint To view the name of the command that will be executed by any toolbar button, simply position the cursor over an item and pause. A “tool tip” will display describing that item.

If you find yourself frequently accessing the commands in one of the fly-outs, you may want to open that toolbar individually. Select Piping > Toolbars, then select the desired toolbar from the menu.

TOUR OF THE INTERFACE DRAWING PREFERENCES


DRAWING PREFERENCES

Now that you are familiar with the basic working environment, the Drawing Preferences command will be examined. Select Piping > Setup > Drawing Preferences… to display the dialog shown below. This command displays the dialog shown below, which enables you to assign values to drawing parameters such as the component size, the specification used to draw components, the drawing mode, line number, etc. It is important to set these parameters prior to beginning work on a new model.

Drawing preferences control how components are placed in the model. For example, the Nominal Size preference defines the nominal main piping size for the next component placed in the drawing. PIPING will use the value of this parameter as part of the query used to search the spec database indicated by the Specification parameter to locate the desired record from that spec. The spec record contains all of the parametric data used to draw the component.

The settings in this dialog are described in the following sub-sections.

Note The defaults that appear in these fields were assigned using the Project Administrator application for the project that you selected when you started the PIPING application. The procedure to modify these defaults is described in the Project Administrator’s on-line help.



DRAWING MODE/REPRESENTATIONS

The Drawing Mode area of the dialog was re-organized in version 2.10 into Drawing Mode and Representation areas to support the implementation of the flat 2D PIPING application. Refer to the 2D Piping Overview in your PIPING help file for more information on this application. 2D PIPING functionality is provided automatically if you purchase the full 3D PIPING application. Users authorized for 2D only, will have their 3D Drawing Mode and associated Representations disabled. Users authorized for 3D will have all draw modes and options available.

The following describes the Drawing Mode and Representations areas of the dialog.

Note 3D-Double Line will be used to denote selecting the 3D Drawing Mode and Double Line Representation.

! 3D-Double Line: this is identical to the previous full 3D Drawing Mode configuration. It enables drawing of 3D components in 3D space using AutoPLANT’s custom objects.

! 3D-Single Line: this configuration enables drawing of Single Line component representations in 3D space using AutoCAD entities. In general, only Pipe Components, Bends and Returns, and Branching Components are actually drawn as single line AutoCAD entities, with a few exceptions. All other components are drawn in standard 3D-Double Line mode.

! 2D-Double Line: this configuration enables drawing of "flat" (i.e., nothing will be drawn in the vertical plane) Double Line representations of components using AutoCAD entities.

! 2D-Single Line: this configuration enables drawing of "flat" (i.e., nothing in the vertical) Single Line representations of components using AutoCAD entities.

As noted above, the 2D - Double Line mode will automatically generate and draw flat 2D. It automatically converts, during placement, a 3D component into 2D native AutoCAD objects, which have been generated via the Hidden Line Removal (HLR) interface.

ADDITIONAL OPTIONS:

! Surface Resolution: When you enable the 3D Drawing Mode radio button, the Surface Resolution setting will be activated. This field is used to assign the value of AutoCAD’s SURFTAB1 and SURFTAB2 environment variables, which control the mesh display of component graphics. A number between 2 and 32766 is required, while a setting of 12 or 16 is recommended. Changing this value does not change the Surface Resolution setting assigned to previously inserted components. Toggle the display of the inherent mesh representation of 3D components with the Piping Tools > 3D Display Modes > Set Mesh command.

! 2D HL Options: When you enable the 2D Drawing Mode radio button, the Surface Resolution option will be replaced by a 2D HL Options button. Pressing this button displays the HLR Options dialog shown below, which enables you to define how hidden line removal is handled



for 2D-Double Line representations. Hidden line removal is handled on a per component basis with respect to the settings defined in this dialog.

The Output Hidden Geometry check box indicates whether or not hidden line output will display for each component. Enabling this check box will activate the Output Properties grid in this dialog. The grid options define the manner in which hidden line output is displayed as described below:

Visibility If the "Light bulb" is ON (yellow), then visibility is turned ON and hidden lines will be visible.

Color Assigns the color of the visible hidden lines.

Linetype Selects the line type to be used for the hidden line. Only loaded line types can be used from this selection and there will be no interface to load line types. The standard CAD interface should be used for this purpose.

Lineweight Determines the weight of the visible hidden lines. When you click within this grid field, a Browse button will appear. Press this button to display a dialog to assign the desired settings. Select the desired Units, then pick the desired line weight to use for your 2D representations.

A brief description of the remaining options in the Drawing Preferences dialog is provided below. Review the descriptions below, then set the starting values as shown in the previous figure and press OK.

FIELD DESCRIPTION

Specification Path Displays the current project’s root specification directory path. Specification databases that exist in this directory will appear as options in the Specification: selection list described below. This path is defined in the project selected when you started this drawing and may be modified using the Project Administrator application.

Specification Lists the specification databases that exist in the Specification Path shown above. Select a spec directory from this list to make it active. New specifications can be created (or existing ones edited) using the Specification Generator application.

Nominal Size Lists the available main nominal pipe sizes that exist in the selected specification’s PIPE table. The selected size is applied to all subsequent components placed in the model, provided the size is available for that component in the specification.

Insulation Thickness Insulation Spec Paint Code

These settings are provided to enable you to specify the value that will be written into the component database record for each of these fields when a component is placed.

Note: To graphically control the display of pipe insulation, enable/disable the Show Insulation check box in this dialog.



FIELD DESCRIPTION

From Component Prompts you to select an existing 3D component and then automatically resets the Drawing Preferences and Project Preferences parameter values to those from the selected component.

This function may also be launched by pressing the From Component icon on the Setup toolbar, or from the first fly-out menu on the Piping Functions Main toolbar.

Component Preferences

Displays a dockable container that enables you to set project and component preferences used to place components. This control is discussed in the following section.

Optimize 2D Graphics

If this check box is enabled, PIPING will examine each port of a component when placed. If the port is not horizontal, and the ports end condition are set to be optimized, then the graphics are optimized at that port. If a vertical component port is found, the entity is changed to the Layer and Line Type specified below.

This option may be enabled manually via the AutoCAD command line as follows:

Enable: (at_PipingSystem_setVariable "Optimized_2d_Graphics" "1")

Disable: (at_PipingSystem_setVariable "Optimized_2d_Graphics" "0")

You can fully customize 2D optimization settings for a project on the Piping > 2D Optimization property page in the Project Administrator application.

Squared Elbow This check box will only be activated for the Single Line Representation. It enables you to specify that you would like to appear as a square angle instead of the default round radius.

Component Color/Layer

These settings determine the set of rules that define component color and layer attributes. Components of the same Size, Layer, Spec, Line No., Paint, or Service value can be colored the same in order to visually distinguish them when viewing the model. Likewise, components can be arranged on the same layer according to their Spec, Service, or Line Number.

Data Mode Determines how settings are applied when routing components. “From Connecting Component,” extracts the component preferences (size, spec, line number, and insulation thickness) from the existing component and applies them to the connecting component that is being placed. This option overrides the Drawing Preferences dialog settings to provide an easy method of maintaining consistency. “From Settings,” will enforce the settings assigned in the Drawing Preferences dialog despite the preferences associated with a connecting component.

Auto Router Mode Enable this switch to automatically connect a selected component to the run end of the previous component. This is the fastest method of placing a series of connected components in a continuous pipeline. If the selected component contains a branch or a bend, you will still be prompted to specify the orientation.

Show Insulation This check box controls the graphical display of insulation on pipe components in the drawing when they are placed.



FIELD DESCRIPTION

Debug Mode This switch should ONLY be enabled if you are customizing/creating component placement scripts or related functions. When enabled, this switch places BasicScript execution in debug mode. When a Basic Script function is executed, it will display in the Rebis Script Editor in Debug Mode to enable you to step through each step of the function as it is executed. This is primarily used to locate/test for errors in customized Basic scripts.

Default Spec Choice When a component is selected for placement, PIPING searches the selected specification for the component record based on the component preferences set in the Drawing Preferences dialog and the type of component selected. If more than one match is found, the Specification Selection dialog displays to enable you to select the desired component from the matching records. For example, several records may exists for a component in a specification that have the same size and type, but may have different facings, end conditions, schedules, ratings, etc.

When the Default Spec Choice switch is enabled, PIPING will automatically place the component marked as the default in the specification automatically, without displaying the Specification Selection dialog. A component may be marked as the default selection by placing a 1 in the OPTIONCODE field of the specification record using the Spec Generator application.

Weld Gaps Welded joints determine the fastener used to connect welded components based on this setting. If the check box is enabled, a weld gap will be inserted using the fastener basic script at_weldedjoint_fasteners to insert AT_WELDGAP. If this check box is disabled, then a weld gap will not be inserted, but a buttweld fastener will be inserted using this script to insert AT_BUTTWELD.

Auto Flange If this toggle is enabled, the application determines if the component's class definition contains the following statement when a component is inserted into the model:

ENABLE_AUTOMATE_OPTION=1

If true, then following the component's insertion, the function attempts to "automate" each open port. It looks in the Auto_Mate specification table for a record that has MAIN_SIZE and END_COND field values that match the open port.

If found, then a component of the class specified in that record is inserted by connecting it to the open port.

Refer to your Specification Generator's online help for instructions on setting up the "auto" tables for this functionality. You can open the Spec Generator help directory via the Windows Start menu selection Bentley > Plant > SpecGen > SpecGen Help.



FIELD DESCRIPTION

Advanced Tap Port Method

The Advanced Tap Port Method is a tap port insertion method that will enable you to create a tap port at any position and any direction. Enabling this check box and then specifying that you want to insert a tap will prompt you for the XYZ position of the tap port, the direction of the tap port, and the tap position projected on the centerline of the pipe (tap port origin).

Note: When you enable this check box, then press OK to close the Drawing Preferences dialog, a dialog will display to enable you to view the help associated with this functionality. You can enable the Never display this dialog again check box to suppress the display of this dialog for future use of this setting.

If the Advanced Tap Port Method check box is enabled, you will be prompted to define the tap port via the following series of prompts:

Pick component to be tapped Toggle/<Enter to select currently highlighted port>: Toggle base port/Align/change Ref point/ <Enter Distance>: Tap port size dialog is displayed Enter Position of tap Enter orientation of tap port

Since you can define a tap off the component that was selected, you will be responsible for the placement, direction and orientation of the tap port. If the Advanced Tap Port Method check box is disabled, then the standard tap port methods implemented in AutoPLANT for the various component types will be used.

Tracing Tracing is basically an electrical form of insulation. For example, it may be used to keep fluid warm enough to flow in piping. This toggle determines whether or not the TRACING drawing database field for components is turned ON (set =1). Used by AUTO-ISO and ISOGEN to indicate that components that have tracing use a different linetype.

Disable Tooltips AutoPLANT now displays an informative tooltip when the cursor is hovered over a component. This will provide a quick view of limited component information (Line Number, Service, Size, Component identity, Schedule, Type). Enable this option to turn off the tooltip display.

AutoPLANT Selections

Indicates whether or not the AutoPLANT Selections dialog is displayed by any command/function that requires a selection set of components. It enabled, the dialog is displayed to enable you to used the advanced features to define a selection set of components. If disabled, you may use standard AutoCAD command to select components.

Once these options are set, all subsequent components will be drawn in that mode until it is changed. You can also generate existing component representations using the new settings.

TOUR OF THE INTERFACE COMPONENT PREFERENCES CONTROL


COMPONENT PREFERENCES CONTROL

AutoPLANT supports relationships through the construct of project objects. These objects inherently create relationships between all components placed based on the values of these objects. These relationships are used by functions (e.g., Reports, BOM, Auto-Iso, Update Components, etc.), which work on a selection set of components. For example, LineNumber is a project object. All components you place with the same LineNumber value are therefore related.

The shipping version of the application provides several project object definitions (LineNumber, Area, Unit, Service, and Spool). You can only define values for these objects using this Project Preferences control, or the Project Object Maintenance Tool. You can only set the active value that will be assigned to a component when placed with the Component Preferences control.

Note The Project Object Maintenance Tool may be launched from the Bentley > Plant > Project Tools folder in your Windows Start menu.

The Component Preferences control shown below can be accessed by either pressing the Component Preferences button on the Drawing Preferences dialog, or by selecting Setup > Component Preferences command from the Piping menu.

Note Since this is a new project, no values have been defined for the required project objects. Press Cancel when the message dialog displays prompting you to define initial project object values. You will add values later in this tutorial.

The preferences shown in this control are defined on an application basis. For example, when working in the PIPING application, the control will only display the project and component



preferences that have been configured for PIPING. You can change the preferences that appear by selecting the desired application Preference Mode from the top toolbar.

DISPLAY MODES

The Component Preferences control is a dockable container that can be docked at left, top or bottom of the AutoCAD application window. Docking at left will essentially provide the same full view and options as the undocked "floating" container shown above. Docking at the top or bottom will display the control in MiniBar mode as shown below.

The minibar mode does not provide options for adding, editing, or deleting preference values. It displays the control as a toolbar, which enables you to simply select the desired values for each setting.

You can control the preferences that appear in the minibar by right-clicking on any of the minibar column headers and selecting Show/Hide Preferences. The Show/Hide Preferences dialog is displayed, which enables you to toggle the display of the preferences shown in the toolbar.

The recommended workflow method is for your Project Administrator to create the available project relationship values in full mode, then your designers may then simply dock the container along the top of the AutoCAD application window to show the control as a minibar. From the minibar mode, they would only be concerned with selecting the appropriate value for each preference from the respective drop-down lists.

PREFERENCES GRID

When the control is displayed in full mode, the grid at the top of the control displays two preference types. Project object preferences are listed at the top, while component preferences are at the bottom. These are separated by a solid black line in the grid. A brief description of these types is provided below.

! Project Preferences: are organized in the upper part of the control grid. These are project relationship preferences (e.g., LineNumber, Area, Unit, and Service). These preferences are used throughout the application to provide quick component selection for updates, reporting, etc. Spool is not provided here as a user typically does not set a spool value to apply to a component during placement, but instead uses the Assign Spool IDs command to assign spool values.



! Component Preferences: are organized in the lower section of the control grid. These are the most common component preferences that may in general also be set via the Drawing Preferences dialog. You may also add new component preferences through this interface. These were included to provide quick access to these settings without having to continuously open and re-open the Drawing Preferences dialog to change these settings.

The grid area will provide three columns. A description of each of these columns is provided below:

Preference The name of the preference.

Current Setting The current setting for this preference. Clicking within this field will display a drop-down list of options defined for this preference. Select the desired option to make it active.

Filter The Filter can be set to any value. This is used to filter the preference list to display only values that contain the specified prefix (e.g., L1* will display only those values in which that begin with "L1").

Separate toolbars are provided for the grid and navigation tree areas of the dialog. The operations that may be performed using these toolbar commands may in general also be selected from context menus that will display when you right-click on a particular preference type or value.

PROJECT PREFERENCES FUNCTIONS

The following table describes the operations that may be performed on project objects via the toolbar, or the context menu that is displayed when you right-click on a project object value.

Add

To add a new project object value, right-click on the project object in the grid or navigation tree, then select the Add option from the context menu displayed. For most of these objects, an editable node will be created under the selected parent project object node. Type the new value then press Enter. For the LineNumber project object, the Create New LineNumber dialog will display to enable you to add a new line number value. If executed from the grid, a separate dialog will display to enable you to enter the new value for each object type.

Rename

To edit the value of an existing project object value, select it in the navigation tree or grid list, then right-click and select the Rename option from the context menu displayed.

Delete

To delete a project object value, select it in the navigation tree or grid list, then right-click and select Delete from the context menu displayed.

Reassign This option is only active in the LineNumber value context menu. Select a LineNumber value in the navigation tree, then right-click and select this option from the context menu to display the Reassign Line Number dialog.

The capabilities provided in this dialog are similar to those in the Database Tools > Update Component command. The dialog enables you to select a source LineNumber value and then select a LineNumber value that you would like to reassign it to. All component records that were assigned to the source LineNumber will be updated (reassigned) to the new target LineNumber value.



Synchronize

This option is only available from the upper toolbar or context menu when working in the upper grid area of the control. It enables you to select a project object value from the grid area, then execute this operation to highlight the corresponding project object value in the navigation tree.

Note Through this interface you can ONLY manage project object values. The addition of a project object (not a value) is considered a Project Administration function. Therefore, this operation may only be performed using the Project Administrator application. This application enables you to launch the Project Object Wizard to add new project objects.

COMPONENT PREFERENCES FUNCTIONS

AutoPLANT provides several examples of component preferences that may be added to the control. This capability is provided to add your most commonly used Drawing Preferences dialog options to this control so they would quickly be available when the control was docked in minibar mode.

The following table describes operations that may be performed on component preferences via the toolbar above the grid, or the context menu that displays when you right-click on a component preference in the grid.

Add

To add a new component preference, right-click on the component preference in the grid and then select the Add option from the context menu displayed. A separate dialog will display to enable you to define the new component preference.

Edit

To edit a component preference definition, right-click on it in the grid, select Edit from the context menu displayed. A separate dialog will display to enable you to modify the preference definition.

Delete

To delete a component preference from the project, right-click on it in the grid then select Delete from the context menu displayed.

NAVIGATION TREE

The control also enables you to view relationship values in a navigation tree view. You can show this tree view in the control by pressing the Relationships button at the bottom of the dialog, or suppress the tree view by pressing the X button to the right of the tree view.

The navigation tree displays the project objects in the current project at the primary node level. Expand a project object node by pressing the + button beside it. This will show all of the values defined for that object in the current project.

Navigation tree operations are performed using the Relationships toolbar, or the context menu displayed when you right-click on a project object or project object value.



The Relationships drop-down enables you to filter the display of projects in the navigation tree. Select a project objects to display, or ALL to display all of the project objects. The remaining toolbar options are described below:

Add

To add a new project object value, right-click on the project object in the grid or navigation tree, then select the Add option from the context menu displayed. For most of these objects, an editable node will be created under the selected parent project object node. Type the new value then press Enter. For the LineNumber project object, the Create New LineNumber dialog will display to enable you to add a new line number value. If executed from the grid, a separate dialog will display to enable you to enter the new value for each object type.

Rename

To edit the value of an existing project object value, select it in the navigation tree or grid list, then right-click and select the Rename option from the context menu displayed.

Delete

To delete a project object value, select it in the navigation tree or grid list, then right-click and select Delete from the context menu displayed.

Properties

Currently properties are only available for LineNumber project object values. If you select a LineNumber value, then right-click and select Properties from the context menu, the Properties Editor dialog will display to enable you to modify the properties for that LineNumber value.

Filter All

If you click on a project object node in the Relationships navigation tree and press this button, it displays a dialog allowing you to filter the values that will display under that project object.

CONTEXT MENUS

A context menu of options displays when you right-click on a node in the navigation tree. The options that display depend on whether or not a project object or project object value is selected.

When you right-click on a project object in the navigation tree, the following options are available in the context menu.

Add Provides the same functionality as the Add toolbar option described above.

Filter Provides the same functionality as the Filter All toolbar option described above.

Sort Provides options to sort the values under the selected project object node in Ascending or Descending order.



When you right-click on a project object value in the navigation tree, the following options are available in the context menu.

Rename Provides the same functionality as the Rename toolbar option described above.

Reassign This option is only active in the LineNumber value context menu. Select a LineNumber value in the navigation tree, then right-click and select this option from the context menu to display the Reassign Line Number dialog.

The capabilities provided in this dialog are similar to those in the Database Tools > Update Component command. The dialog enables you to select a source LineNumber value and then select a LineNumber value that you would like to reassign it to. All component records that were assigned to the source LineNumber will be updated (reassigned) to the new target LineNumber value.

Delete Provides the same functionality as the Delete toolbar option described above.

Properties Provides the same functionality as the Properties toolbar option described above.

The Spool node is only provided in the navigation tree for convenience. It enables you to view the currently defined Spool IDs in the project. Although you may ceate new Spool ID values from this tree, they are not used by the application, since a Spool ID must manually be entered when assigning these values to components using the Assign Spool IDs command.

TOUR OF THE INTERFACE CHAPTER REVIEW


CHAPTER REVIEW

! Interface: The PIPING interface has been designed to provide easy access to components and commands. The use of toolbars, in particular, aids in component selection by providing quick access and always displaying the most recent selection made from a component group. The toolbars can be resized and positioned along the perimeter of the drawing area.

! Drawing Settings: The Drawing Preferences dialog enables you to customize parameters used in a drawing session. Through a single dialog, the specification, drawing mode/representation, main size, connectivity check, and other options can be controlled.

! Component Preferences: The Setup > Component Preferences displays a dockable control, which enables you to add, edit, and delete project and component preference values.

COMPONENT PLACEMENT BASICS OVERVIEW


OVERVIEW

This chapter provides an introduction to component placement. It begins by reviewing the basic placement procedure, then moves on to exercises that focus on the more sophisticated placement concepts and techniques. Component placement from plan and perspective views will also be covered in these exercises.

BASIC PLACEMENT PROCEDURE

The basic component placement procedure involves four generic steps. The prompts provided at each stage are dependent on the component type and how it is being placed in the model.

1. Select the component: Components may be selected for placement from the toolbars or the menu system.

2. Specify a reference and placement point: Components are always placed with respect to a reference point. In most cases, the reference point and the placement point are one and the same because the default reference point is always the end point of the component previously placed in the model. You can attach a component directly to this reference point, place it a known distance from this point, or select one of the following options:

+ “In space”: not connected to another component, centerline, or piece of equipment. In this case, the user picks (or inputs) a new point in the model, which becomes the reference point. You can also specify an elevation prior to picking the point.

+ Inserted on an intelligent centerline: The component run direction and orientation will be extracted from the geometry of the centerline. The component will also assume the size, spec, and line number attributes from the line, if they were defined.

+ Aligned with existing components: A component can be placed so that its centerline automatically aligns with the centerlines of two existing components.

Placed “in space” Inserted on a centerline Tee aligned with two existing elbows

COMPONENT PLACEMENT BASICS BASIC PLACEMENT PROCEDURE


3. Toggle insertion point: If you specify the reference point on an existing component, you can toggle to any of the connecting component’s ports to specify the port that you want to connect to on the existing component. For example, a tee may be inserted with respect to either of its main run end ports, center point, or branch port as shown below (some components, such as pipe, do not have a center point or a branch end and do not provide this prompt option).

Endpoint Centerpoint Branch

4. Orient the component: Many components have a branch or bend that must be oriented separately (for example, when placing an elbow, the downstream leg can be placed in the X, Y, or Z plane, or rolled along a specified angle). This prompt will only appear for component placements that require it.

Some examples of how a Tee may be oriented

Each of these steps is covered in the exercises provided in the following sections. These exercises illustrate how to combine the placement options to produce the desired results. After a little practice, you will find that these options enable you to position and place components with ease and precision.

COMPONENT PLACEMENT BASICS COMPONENT SELECTION


COMPONENT SELECTION

PIPING components can be selected from either the Piping menu or the Piping Components Main toolbar.

Note The components shown in this section are part of the default carbon steel module shipped with PIPING. Several other component modules are also provided with your software, and can be loaded with the Setup > Module Setup… command. Each module provides its own component placement menu and toolbar.

PIPING MENU

The Piping menu, shown below, provides access to the complete range of components. Note that component types are grouped together in the Piping menu in a set of "cascading" submenus.

Piping components are groupedtogether in cascading menus.

COMPONENT PLACEMENT BASICS COMPONENT SELECTION


PIPING COMPONENTS MAIN TOOLBAR

The Piping Components Main toolbar is shown below. Like the menu system, the toolbar provides access to the complete range of components, and categorizes components into similar types. The toolbar also has the added advantage of displaying the last selection made from one of its “flyout” toolbars. This technique enables you to quickly access the most recent component selections.

Hint Because the Piping Components Main toolbar is used so frequently, experiment with its positioning. It can be docked at the top of the screen just below the AutoCAD toolbars, at the bottom of the screen above the command line, or at the left or right edge of the drawing area.

DIRECTION AIDS

The Direction Aids toolbar shown below may be used to specify the orientation of a component in response to the component placement prompts. These tools are particularly useful when placing components that run towards or away from the viewer in the current plane, or when working in a skewed view.

COMPONENT PLACEMENT BASICS BASIC PLACEMENT EXERCISES


BASIC PLACEMENT EXERCISES

This section provides some working exercises that demonstrate the range of component placement commands. Exercises include the following:

+ Placement in space

+ Connecting components

+ Placing from a reference point

+ Placing components in a skewed view

+ Aligning components

+ Attaching to a centerline

+ Automatic pipe placement

+ Placing components into existing pipe

GETTING STARTED

The procedure to start PIPING was provided in the previous chapter. If you do not already have the PIPING application loaded, follow the generic procedure outlined below.

> TO START PIPING

1. Select Programs > Bentley > Plant > Plant Design from the Windows Start menu.

2. Select AutoPLANT 3D > Piping to start the PIPING application.

3. When the Open Project dialog displays, select the project from the list for the environment in which you would like to complete this tutorial (IMPERIAL_TUTOR or {METRIC_TUTOR}, then press OK.

4. When Login dialog displays, enter the User Name and Password that was given to you by your Project Administrator then press OK.

5. When the Model Setup dialog displays, check to ensure that the North direction is set to 90 (degrees), and that the World Length is 100’ {30000} and the World Width is 60’ {18000}. Also ensure that the Insert North Arrow and Draw Limits Box options are enabled, then press Done. After the dialog closes, pick a point in the upper right corner of the drawing area to place the north arrow.

6. Open the Piping Components Main, Piping Functions Main, Direction Aids, and Responses toolbars from the Piping > Toolbars menu.



SETTING INITIAL DRAWING AND COMPONENT PREFERENCES

In this section, you will set the initial drawing and component preferences that will be used to insert components. Drawing preferences control how components are placed in the model. For example, the Nominal Size field defines the nominal main piping size for the next component placed in the drawing. PIPING will use the value of this parameter as part of the query used to search the spec database indicated by the Specification parameter to locate the desired record from that spec. The spec record contains all of the parametric data used to draw the component.

> SET INITIAL DRAWING PREFERENCES

1. Select Setup > Drawing Preferences from the Piping menu to display the Drawing Preferences dialog.

2. Set the Specification to cs150 {mcs150}.

3. Set the Nominal Size to 6” {150mm}.

4. Press OK to apply the changes.

As mentioned earlier in this Tutorial, the recommended workflow method would have your Project Administrator create the available project values (e.g., LineNumber, Area, Unit, and Service values) available in a project, then designers would simply select the desired value prior to placing components. Project relationship values may be created in the Project Preferences control, or outside of AutoCAD using the Project Object Maintenance Tool application. In this section, you will define a set of project object values that will be used in this chapter.

> CREATE INITIAL COMPONENT PREFERENCE VALUES

1. Select Setup > Component Preferences from the Piping menu to display the Component Preferences control.

2. Press the Relationships button to display the navigation tree view if not already shown.

3. Right-click on the LineNumber node in the navigation tree, then select Add from the context menu displayed.

4. The Create new Line Number dialog displays as shown in the following figure. Type LINE_100 as shown in the first field, then press OK to add the new LineNumber value to the project. This LineNumber value will now be available to any drawing created for this sample project.



5. Right-click on the Area node in the navigation tree, then select Add from the context menu displayed. An editable node will appear in the navigation tree below the Area parent node. Overwrite the value shown by typing AREA_100 and pressing Enter.

6. Right-click on the Unit node in the navigation tree, then select Add from the context menu displayed. An editable node will appear in the navigation tree below the Unit parent node. Overwrite the value shown by typing UNIT_100 and pressing Enter.

7. Right-click on the Service node in the navigation tree, then select Add from the context menu displayed. An editable node will appear in the navigation tree below the Service parent node. Overwrite the value shown by typing SERVICE_100 and pressing Enter.

8. In the grid area at the top of the control, ensure that the following values are set in the respective Current Setting drop-down lists so that they are active.

LineNumber LINE_100

Area AREA_100

Unit UNIT_100

Service SERVICE_100

9. Press the X button in the upper right hand corner of the control to close it.



PLACEMENT IN SPACE

In this exercise, you will learn how to place a standard piece of pipe in space.

> TO PLACE A PIECE OF PIPE IN SPACE

1. Select Piping Tools > Display Modes > Set Wireframe w/Centerline to ensure that the component display mode is set as illustrated throughout this tutorial.

2. Select Piping > Pipe Components > Pipe. The prompt

Elevation/<Pick point>:

displays. Type E and press Enter to display the Set Elevation dialog shown below.

Ensure that the Center of Pipe radio button is enabled as shown above, then type 6’ {1800mm} in the Elevation field and press OK to set the AutoPLANT elevation to 6-feet (1800mm).

3. The prompt

Elevation/<Pick point>:

displays. Pick any point near the left edge of the drawing area.

4. The prompt:

Connect to/<Enter Length>:

displays. Note that a ghost line “rubber bands” from the initial point. You can either pick the distance from the original point, or input a length at the command line. Type 10’ {3000} then press Enter to specify a ten-foot {3000mm} length of pipe.

Hint By default, the Imperial Configuration uses architectural units. You can change the unit type and precision with AutoCAD’s DDUNITS command.

5. The prompt

Up/Down/East/West/North/South/Align/<Enter direction or press Return when done>:

displays. This last step orients the component. For example, if a point is selected to the right of the insertion point (with ORTHO ON [F8]), the pipe will extend in the +X direction from the base point. You can also use the Direction Aids toolbar to specify this information. For example, press the +X button on the Direction Aids toolbar then press Enter to place the pipe as shown below.



1

Distance

Placement Point

2

Direction

Note The direction vector is necessary because the pipe is being placed “in space.” When connecting to an existing component, the direction vector is determined automatically.

6. Use AutoCAD’s zoom controls to view the entire length of the pipe segment. Leave some extra space to place additional components.

> PLACING AN ELBOW IN SPACE


2. The prompt

Current Elevation <COP 6’>: Relative/Toggle/Elev/<Pick point or Return for fit-fit)>:

displays. Notice that PIPING assumes you want to attach the elbow to the end of the pipe. Override this default by picking a new point in space (i.e., a point NOT on or near the existing pipe).

3. An outline of the elbow is placed in the drawing as shown in the Figure below, and the prompt

Toggle insertion point/<Return to select>:

displays. Note that by default, the center point of the elbow is selected as the insertion point.

Insertion point symbol

Hint By default, whenever you place a bend or branching component “in space,” PIPING assumes that you want to insert it from its center point.

4. To toggle a component’s insertion point, press the Toggle icon on the Responses toolbar, or type T and press Enter at the command line. The Figure below illustrates how the insertion point will toggle for an elbow and a tee.



= Insertion point

TEEELBOW

Continue to Toggle the reference point until the elbow port shown below is selected, then press Enter, or click the right mouse button, to accept this point.

Press the button until theinsertion icon appears asshown.

Hint Pressing the right mouse button is the equivalent of pressing Enter. This technique is standard to all AutoCAD operations that request the user to pressEnter at the command line.

5. The prompt

Up/Down/East/West/North/South/Align/<Enter direction or press Return when done>:

displays, and a “ghost line” extends from the point specified in Step 4. Specify the run direction of the elbow by selecting a point any distance to the left of the anchor point (with ORTHO ON[F8]), or press the --X icon on the Direction Aids toolbar. Press Enter.

6. The prompt

Up/Down/East/West/North/South/Align/Rotate/reseT/<Enter orientation or press Return when done>:

displays. The Direction Aids toolbar is particularly useful for specifying an orientation that is difficult to pick in the current viewing plane (for example, specifying that an elbow should be oriented vertically while working in the plan view). The following Figure illustrates a few elbow orientations that may be obtained using the Direction Aids toolbar options.

- Z+Z- Y+Y



To specify the orientation of the elbow leg, pick a point any distance below the last point picked, or press the -Y icon on the Direction Aids toolbar. Press Enter to draw the elbow as shown below.

You should use the new Piping Tools > Component Manipulations Tools > Delete Components command when you want to delete a component. This command ensures that the components and also all fasteners and/or attachments associated with them are deleted. Delete the elbow using this command now.

Note Later in this tutorial, you will learn how to “clean” the external drawing database to ensure that the records in the database are synchronized with the model.



CONNECTING COMPONENTS

When connecting components in PIPING, the software can automatically “snap” to the open end of the last component placed. This feature, along with a Connectivity Checker, helps to ensure that components are connected properly, and that their end conditions are compatible. The following exercises demonstrate how to connect components using the fitting to fitting method. The default mode is demonstrated first, followed by an exercise that utilizes the AutoRouter.

> TO CONNECT COMPONENTS MANUALLY


2. The prompt

Current elevation <COP 6'> Relative/Toggle/Insert/Elev/<Pick point or Return for fit-fit>:

displays. Pick a point on the east end of the pipe that was drawn earlier. The reference point is moved to that location.

3. The prompt

displays again. Press the right mouse button (or Enter ) to connect to the end of the pipe using the “fitting to fitting” method.

4. The prompt


displays. Pick a point straight down, or press the -Y button on the Direction Aids toolbar. Press Enter to complete the connection as shown in the graphic below.



> TO CONNECT USING THE AUTO-ROUTER

1. Select Piping > Setup > Drawing Preferences… to open the Drawing Preferences dialog.

2. Enable the Auto Router Mode check box, and then press OK to close the dialog.

3. Select Piping > Flanges > Weldneck. The Specification Selection dialog displays as shown below to enable you to specify the desired flange. In instances where there is more than one valid record in the specification, the selection dialog will display to enable you to select the desired component. The records in this dialog may contain different end conditions, ratings, schedules, or other unique fields, but otherwise meet the requirements specified in the Drawing Preferences dialog.

4. Select the 150LB RF flange record, then press OK. The flange is attached to the elbow as shown below. Note that you did not have to specify the connection point. When the Auto Router switch is set, PIPING automatically attaches to the previous component using the “fitting to fitting” method.

5. Select Piping > Flanges > Weldneck again. The model appears as shown in the following Figure.

Note If a Specification Selection dialog displays, select the first gasket record in the Specification Selection dialog, then press OK.



PLACING FROM A REFERENCE POINT

At this point, all of the components were either placed “in space” or connected to existing components. In this section, you will learn how to place a component a specified distance from a reference point.

To insert a component a specific distance from the center point of another,use the Relative option then input or pick a distance.

> TO PLACE A COMPONENT FROM A REFERENCE POINT

1. Before you start, adjust the view of the model so that you can place components south and east of the elbow. Use AutoCAD’s zoom controls and scroll bars to obtain a view similar to the one shown below.

2. Select Piping > Setup > Drawing Preferences… and disable the Auto Router Mode check box, then press OK. Components cannot be placed from a reference point until this switch is disabled.



3. Select Piping > Branching Components > Straight Tee. The reference point is automatically selected at the open end of the flange.

4. The prompt

Relative/Elev/<Pick point or Return for fit-fit>: R

displays. Type R and press Enter to select the Relative option.

5. The prompt

displays. Type 5’ {1500} and press Enter to place the tee 5-feet {1500mm} away from the end of the last flange.

6. The prompt

Toggle insertion point/<Return to select>: T

displays, and an outline of the component appears at the placement point. You must now indicate whether the end point, center point, or branch point of the tee is to be placed at that point. Type T and press Enter to Toggle the reference point to the end of the tee, then press Enter to accept the point.

7. The prompt

Toggle alignment port/<Return to select>:

displays. Press Enter to accept the default position.

8. The prompt


displays. Orient the tee so that its branch extends eastward. With ORTHO ON, select any point to the right or press the +X button from the Direction Aids toolbar. Press Enter to place the tee relative to the flange as shown in the figure below.



> CHANGING THE REFERENCE DIRECTION

1. In this exercise, you will place an elbow using the center point of the tee as a reference. You will place the elbow so that one of its legs moves away from the plan view. Select Piping > Bends and Returns > 90°°°° LR Elbow.

2. The prompt

Relative/Toggle/Elev/<Pick point or Return for fit-fit>: T

displays. Continue to type T and press Enter until the branch tee port is selected.

When the tee branch port is highlighted, type R and press Enter to choose the Relative placement option.

3. The reference point becomes the center of the tee and the prompt

Toggle /Align/change Ref point/<Enter Distance or Return for fit-fit>: T

displays. Notice that there are two points highlighted: the center of the tee, which is the reference point, and the north end of the tee, which indicates the desired run direction. Press the Toggle option until the branch end of the tee is highlighted as shown in the graphic below. You can now place the elbow a specified distance along the branch direction.

4. The prompt

Toggle /Align/change Ref point/<Enter Distance or Return for fit-fit>: 5’ {1500}

displays. Type 5’ {1500} and press Enter to pick the placement point 5-feet {1500mm} away from the center of the tee.

5. An outline of the elbow appears at that point and the prompt


displays. Type T and press Enter until the reference point toggles to the end of the elbow, then press Enter to accept the point.



6. The prompt


displays. Orient the elbow so that its leg runs towards the viewer in the plan view. Press the +Z button on the Direction Aids toolbar. Press Enter to place the elbow in the model with its leg running up in the vertical plane. In the next exercise, you will work from a skewed viewpoint. The model, as it appears in the plan view, is shown in the following figure.

PLACING COMPONENTS IN A SKEWED VIEW

PIPING is designed to produce clean production drawings from any view (see the discussion on Drawing Modes later in this chapter). In the development of a 3D model, piping lines may be easier to visualize, and it may be easier to discover design flaws, while working in a different viewing perspective. PIPING enables you to route components in a skewed view as easily as from the Plan view. You will also find working in a skewed view makes it easier to place components that are oriented perpendicular to the current viewing plane (i.e., oriented in the +/- Z direction). The exercise below demonstrates this process.

You should make extensive use of AutoCAD’s View commands, and/or the View toolbar. These commands enable you to quickly move around the model to a number of pre-defined viewing perspectives. Particularly useful for controlling views is the View toolbar shown below. From this toolbar, users can easily toggle between plan, elevation, and isometric viewing planes of the current model. Refer to your AutoCAD documentation for more information.

First, you will change the viewpoint, then continue placing components on the pipe run created earlier.



> TO CHANGE THE VIEWPOINT

1. Type VPOINT and press Enter, and then type -1,-1,1 and press Enter, or select the SW Isometric View icon from AutoCAD’s View toolbar.

2. Zoom in around the area of the model shown below. Note that the last elbow placed is oriented in the vertical plane.

Routing from a skewed view is no different from routing in the plan. The only difference is that you are better able to visualize the model and can easily select objects that may be hidden when viewing the drawing from a plan perspective.

> TO PLACE COMPONENTS IN A SKEWED VIEW

1. Select Piping > Reducers and Swages > Concentric Reducer.

2. The prompt

Current Elevation <COP 6’> Relative/Toggle/Elev/<Pick point or Return for fit-fit>:

displays. Whenever a component is placed from a reference point, the application will assume that you want to route back to the original point. Select the vertical leg of the elbow to begin routing in the vertical direction, or use the Toggle option to select the vertical port. Note that you can pick anywhere near the endpoint of the elbow. It is not necessary to use the ENDP osnap, as PIPING will automatically recognize any point that is selected reasonably near the end of the elbow graphic.

3. The prompt

Current Elevation <COP 6’> Relative/Toggle/Elev/<Pick point or Return for fit-fit>:

displays. Press Enter to connect using the “fitting-to-fitting” method.



4. The Specification Selection dialog displays as shown below. This dialog will always display when placing a reducer to enable you to define the reduced size (remember, only the main size is set from the Drawing Preferences dialog). Select the 6X4 {150 x 100} Buttweld Concentric Reducer record from the Specification Selection dialog, then press OK.

5. The reducer is placed in the model as shown in the figure below.

6. Select Piping > Branching Components > Straight Tee to add a tee to the end of the reducer.

7. The prompt

Current elevation <COP 6'> Relative/Elev/<Pick point or Return for fit-fit>:

displays. Press Enter, or press the right mouse button, to connect to the end of the reducer.

8. The prompt


displays. Press Enter to accept the default insertion point.

9. The prompt


displays. Press +Y on the Direction Aids toolbar to orient the branch in the +Y direction. Press Enter to complete the tee placement as shown in the following figure.



Note Notice that a 4” {100mm} tee was connected to the reducer. One of the default settings in the Drawing Preferences dialog enables you to automatically match the settings of the last component placed in the drawing. Also of note is the color of the tee. A separate setting in the Drawing Preferences dialog controls how colors are assigned in PIPING. By default, objects that share a nominal size are colored the same so that size ranges can be easily distinguished in the model.

ALIGNING COMPONENTS

Refer to the Figure above. Suppose you were to remove the 6” {150mm} tee that is aligned with the flange and the upward turning elbow. To place it again, you would have to find the intersection point between the two centerlines. In the past, this meant routing centerlines or construction lines to determine the point, or getting out the calculator to compute the desired insertion point. With PIPING, aligning a component to existing centerlines has never been easier.

> TO ALIGN COMPONENTS

1. To begin this exercise, erase the 6” {150mm} tee that you placed earlier. Select Piping Tools > Component Manipulation Tools > Delete Components, then pick a point on the outline of the tee and then press Enter. The model appears as shown below.

2. Now you will re-insert the tee using the Align option. Select Piping > Branching Components > Straight Tee.

3. The prompt

Current elevation <COP 6'> Relative/Elev/<Pick point or Return for fit-fit>:

displays. PIPING assumes you want to continue routing off the 4” {100mm} tee. Select the open end of the flange instead.



4. The prompt

Current elevation <COP 6'> Relative/Elev/<Pick point or Return for fit-fit>: R

displays. Type R(elative), then press Enter.

5. The prompt

Align/change Ref point/<Enter distance or Return for fit-fit>: A

displays. Type A(lign), then press Enter.

6. The prompt

Pick component to align to

displays. Select the open end of the upward-turning elbow.

7. The prompt

Toggle/<Enter to select currently highlighted port>

displays, and the two selected alignment ports are highlighted. Confirm that you want an insertion point placed at the intersection of these two ports by pressing Enter.

8. An outline of the tee is inserted at the specified point, and the prompt


displays. Press Enter to place the tee at its center.

9. The prompt


displays. You can toggle the connection port so that the branch or a run end is facing toward the flange. Press Enter to accept the default port alignment.

10. The prompt


displays. Pick a point in the +X direction, or press the +X button on the Direction Aids toolbar to indicate the branch direction of the tee. Press Enter to place the tee aligned with the centerline of the flange and elbow as shown in the following figure.



ATTACHING TO A CENTERLINE

Another method of component placement is to place a component directly on a centerline. PIPING provides centerline router functions to enable you to define a piping path with a high degree of precision. Components can then be placed directly on the line to ensure placement at proper elevations. In this exercise, you will route a simple centerline, then place an elbow on it to demonstrate this feature.

> TO ROUTE THE CENTERLINE

1. Zoom out to give yourself more room to draw the centerline.

2. Select Piping > Piping Tools > Centerline Routers > From Dialog to display the Router Line Info dialog shown below. With Info Mode ON, the current drawing preferences are stored on the line. When a component is placed on the line, settings such as main size, insulation, line number, etc. will be automatically assigned to that component. For the purposes of this exercise, however, enable the Info Mode Off radio button as shown below, then press OK.

3. The prompt

Exit/<Options>/Start Point: end

displays. Type END and press Enter, then select the endpoint of the tee as shown in the following Figure.



Select the endpointof the tee.

If the end was not picked as shown above, type T and press Enter to toggle the selection point until the end is selected. Press Enter when the point is selected as shown to accept this point.

4. The prompt

Exit/<Options>/Pick Point:

displays. Press Enter to display the Routing options dialog shown below.

5. To pick the next point 5-feet {1500mm}south from the end of the tee, scroll down and select South from the Options list, type 5’ {1500} in the Distance field, then press OK to pick the point.

6. Press Enter to return to the Router dialog.

7. To pick the next point sloping at a 45-degree angle, select Sloping from the Options list, type 45 in the Z Angle field, then press OK.

8. The Towards/Away dialog displays. Select Towards then press OK.



9. The prompt

Next point:

displays. Type @5’<0 {1500<0} at the command line, then press Enter.

10. Type E and press Enter to complete the centerline as shown below.

> TO ATTACH TO THE CENTERLINE

1. You can now place an elbow at the intersection point. PIPING will roll the elbow automatically. Select Piping > Bends and Returns > 90°°°° LR Elbow.

2. The prompt

Current elevation <COP 6'> Relative/Toggle/Elev/<Pick point or Return for fit-fit>:

displays. Pick a point near the corner of the centerline that was just created. PIPING will automatically recognize the intersection as the desired point and place the elbow.

Note Notice that the insertion point and orientation prompts were bypassed, and the elbow graphic was placed without further interaction.



AUTOMATIC PIPE PLACEMENT

The AutoPipe command is provided to enable you to place straight pipe between existing fittings. The process is as simple as selecting the components between which pipe should be placed.

> TO ROUTE PIPE AUTOMATICALLY

1. Select Piping > Pipe Components > AutoPipe.

2. The AutoPLANT Selections dialog displays. This is a common component selection dialog that provides options to define the selection set of components for which the executed command will apply. Options are available to select components that share user-defined attributes, or to select components that exist in one or more project drawing (useful when generating reports or updating a particular field value for all components in a project). In this example, you will manually select the components between which pipe should be placed. Click on the Drawing tab, then enable the All radio button, then press OK.

3. Connecting pipe is placed between the components. Notice that AutoPipe recognized the branch run on the tee. Type REGEN and press Enter. The model appears as shown below.



INSERT INTO PIPE

PIPING also provides a component placement feature which enables you to insert a component into an existing pipe segment. This feature will automatically break the pipe to insert the component, then connect the pipe to the component if possible.

> TO INSERT A VALVE INTO PIPE

1. Select Piping > Valves > Gate > Gate.

2. The prompt

Current elevation <COP 6'> Elevation/Insert/<Pick point>:

displays. Pick any point on the first pipe segment you placed in this chapter.

3. The prompt

Current elevation <COP 6'> Relative/Insert/Elev/<Pick point or Return for fit-fit>:

displays. Type I(nsert) and press Enter to indicate that you want to insert into the selected pipe segment.

4. You will notice that the entire pipe segment is highlighted and the prompt

Select reference port Toggle/<Enter to select currently highlighted port>:

displays. Toggle until the port on the open end of the pipe segment is highlight, then press Enter.

5. The prompt

Align/change Ref point/Enter distance <0.0>

displays. Type 2’ {600} and press Enter to specify the location of the valve insertion point from the highlighted pipe segment port.

6. The Specification Selection dialog displays. Pick the first buttweld (END_COND_1=BW) valve record, then press OK.

7. Press Cancel when the AutoPLANT Selections dialog displays to indicate that you do not want to also insert topworks with the valve.

8. The prompt


displays. Press Enter to insert the valve using its default insertion point port.



9. The prompt

Toggle alignment port/<Return to select>

displays. Press Enter.

10. Notice how PIPING breaks the pipe segment, inserts the valve, then re-attaches the pipe to both ends of the valve complete with buttweld fasteners as shown below..

COMPONENT PLACEMENT BASICS DISPLAY MODES


DISPLAY MODES

PIPING components are constructed from a series of Rebis Custom Objects, which have inherent display properties. PIPING provides the Display Mode options to enable you to instantaneously display components using any of the four inherent display modes. These display modes do not affect the size of the drawing. These commands may be executed from the Piping > Piping Tools > Display Modes menu, or from the Display Modes toolbar (flyout of Piping Tools toolbar).

Wireframe Mode Centerline Mode

Wireframe with Centerline Mesh

Note The mesh density used to display components in the Mesh Display Mode is defined by setting the value of the Surface Resolution in the Drawing Preferences dialog prior to component placement.

COMPONENT PLACEMENT BASICS CHAPTER REVIEW


CHAPTER REVIEW

+ Basic Placement Procedure: To insert a component, select it from the menu or toolbar, indicate its placement point, then orient the component for branches and bends. Within each of these basic steps, the user has a variety of options available.

+ Fitting to Fitting: Because most components are placed using the fitting-to-fitting method, PIPING automates many of these tasks. To connect a component to the previous one, simply select the new component, then press the Enter key, or the right mouse button.

+ Insert into Pipe: PIPING provides a component placement feature which enables you to insert a component into an existing pipe segment. This feature will automatically break the pipe to insert the component, then connect the pipe to the component if possible.

+ Working in a Skewed View: PIPING is a true 3D package. To fully utilize its power, you can work in a three-dimensional view using AutoCAD’s standard View commands and controls.

+ Other Placement Options: In addition to the automated placement capabilities, PIPING allows components to be placed with a great deal of precision and accuracy. Toggle the Relative command to change the reference point from which a component is placed. The Align command can be used to orient two components along the same centerline.

+ Drawing Mode: The drawing mode switch can toggle the display of the model between various inherent custom object display properties. Changing the drawing mode does not affect drawing size.

WHAT’S NEXT

In Chapter 5 you will use the techniques introduced in this chapter to construct a simple piping model. You will begin by opening an equipment drawing that is provided with your sample project. You will then learn to connect PIPING components directly to the existing nozzles. Two piping lines will be constructed. You will also take a closer look at some of the tools that are available to automate piping tasks.

ROUTING PIPE AND FITTINGS OVERVIEW


OVERVIEW

This chapter builds upon the connection methods discussed in Chapter 4. A drawing has been provided with your sample project that contains the vertical and horizontal vessels shown below. You will begin by connecting pipe directly to the nozzles on these vessels, then execute various connection and placement techniques to construct the simple pipe run shown here. At the completion of this chapter, you will be capable of placing any arrangement of components as shown below.

The simple model shown at rightwill be created during this chapter.Individual exercises focus ondifferent aspects of the pipinginterface and on placementtechniques.

OPENING THE DRAWING

You imported the sample drawing that will be used in this section of the Tutorial in Chapter 2. This two-vessel drawing was created using AutoPLANT EQUIPMENT, and contains vessels and nozzles with pre-defined line numbers. This will help to demonstrate the advantage of sharing model data between AutoPLANT applications. For example, the LineNumber and Size settings are automatically extracted when connecting PIPING components to EQUIPMENT nozzles. To open the equipment drawing, follow the procedure outlined below.

Note You can also connect to xreferenced drawings, which share the same Workspace. Workspaces allow several designers to share each other’s models. This powerful feature of AutoPLANT is discussed in greater detail in Chapter 7, Drawing Production.

> TO OPEN THE PIPE_TUTOR {PIPEM_TUTOR} MODEL

1. Select Programs > Bentley > Plant > Plant Design from the Windows Start menu.

2. Select File > Open. Press No when prompted to save the current drawing. When the file selection dialog appears, navigate to the …\TutorProject\IMPERIAL_TUTOR\TUTORIAL {…\TutorProj\METRIC_TUTOR\TUTORIAL } directory on your local drive. Open the file PIPE_TUTOR.DWG {PIPEM_TUTOR.DWG}.

ROUTING PIPE AND FITTINGS OPENING THE DRAWING


3. Press OK when the proxy graphics dialog displays.

4. Select AutoPLANT 3D > Piping to start the PIPING application.

5. You may have noticed that you were not prompted to select a project. This is because the system automatically resolves that the PIPE_TUTOR {PIPEM_TUTOR} drawing belongs to your tutorial project.

6. Select Piping Tools > Display Modes > Set Wireframe w/Centerline to set the display mode used in this Tutorial. Type Regen and press Enter, then Zoom Extents to display the model as shown below. Note that there are two nozzles on the horizontal vessel and one on the vertical vessel. These vessel's and their associated nozzles were created using the AutoPLANT EQUIPMENT application.

7. Open the Piping Components Main, Piping Functions Main, Direction Aids, and Responses toolbars from the Piping > Toolbars menu if not already displayed.

ROUTING PIPE AND FITTINGS DRAWING SETTINGS


DRAWING SETTINGS

An overview of the Drawing Preferences dialog was provided in Chapter 3 of this Tutorial. The first step in beginning a new drawing session is to establish the initial drawing preferences that will define the search criteria used to place components. For example, PIPING will use the values specified for Nominal Size and Specification to locate the component record in the specification that matches the criteria. This record contains the parametric information used by PIPING to draw the component.

> TO ESTABLISH INITIAL DRAWING SETTINGS

1. Select Piping > Setup > Drawing Preferences… to display the dialog shown below.

2. You will initially use the drawing preference values shown above. Ensure that your drawing preferences match those shown above, and then press OK. These settings will enable you to place 3D 6” {150mm} components from the CS150 {MCS150} specification.

Note The default values in this dialog are saved on a project-by-project basis. You can modify these defaults using the Project Administrator application, which can be launched from the main AutoPLANT menu or toolbar. The specification used in this tutorial, CS150 {MCS150}, is the IMPERIAL_TUTOR {METRIC_TUTOR} default spec. You can create your own specifications using the Spec Generator application, and then access those records for use in your own projects by setting the active specification in this dialog. Specifications must be stored in the directory listed in the Specification Path field, which is also saved with the project configuration.

ROUTING PIPE AND FITTINGS COMPONENT PREFERENCES


COMPONENT PREFERENCES

PIPING uses the value of several project objects to form relationships between components, documents, etc. in a project. The Project Preferences control provides a tool to manage the values of these project objects. The shipping version of the application provides four project objects that must be defined: LineNumber, Area, Unit, and Service in order to place components. Definition of Spool project object values is optional for component placement

As noted earlier in this Tutorial, the recommended workflow method would have your Project Administrator create the project values (e.g., LineNumber, Area, Unit, Spool, and Service values) available in a project, then designers would simply select the desired values prior to placing components. In this workflow method, designers would not need access to the full set of Component Preferences control features and should simply dock the container along the top of the AutoCAD application window to show the control as a MiniBar. From the MiniBar mode, a designer would only be concerned with selecting the appropriate project object values from the drop-down lists.

When the PIPE_TUTOR {PIPEM_TUTOR} model that you opened at the start of this Tutorial was created, values were added to the project for the LineNumber project object in order to place the nozzles that are connected to the vessels.

Select Setup > Component Preferences to display the control. If you open the LineNumber project object’s Current Setting drop-down list, you will notice that line numbers L1000 and L2000 are already available in the project. These were the LineNumber values assigned to the vessel nozzles.

In order to conform to our recommended workflow method, you will create the remaining project object values used by this Tutorial now. You will then be able to dock the control so that it displays as a MiniBar, then simply select the desired values for the project objects as you progress through the Tutorial.

As noted previously LineNumber values L1000 and L2000 exist in the project database. You will add LineNumber L3000, and then values for Area, Service, and Unit.



> TO CREATE THE TUTORIAL PROJECT OBJECT VALUES

1. Select Piping > Setup > Component Preferences to display the control shown below (if it is not already open).

2. Right-click on the LineNumber node in the navigation tree or the LineNumber preference in the grid area of the dialog, then select Add from the context menu displayed.

3. Type L3000 in the Create new Line Number dialog as shown below, and then press OK.



This will add the new LineNumber value to the project. A node for this LineNumber will appear in the navigation tree and will be available for selection in the Current Setting drop-down list.

4. Right-click on the Area node in the navigation tree or the Area preference in the grid area of the dialog, then select Add from the context menu displayed.

5. An editable node will be added below the Area parent node in the navigation tree. Overwrite the default value by typing PT1000 and pressing Enter.

6. Right-click on the Unit node in the navigation tree or the Unit preference in the grid area of the dialog, then select Add from the context menu displayed.

7. An editable node will be added below the Unit parent node in the navigation tree. Overwrite the default value by typing U1000 and pressing Enter.

8. Right-click on the Service node in the navigation tree or the Service preference in the grid area of the dialog, then select Add from the context menu displayed.

9. An editable node will be added below the Service parent node in the navigation tree. Overwrite the default value by typing S1000 and pressing Enter.

10. Now that your project objects are defined, you can dock the control. Drag the control to the top of the AutoCAD display area, and then release your mouse button. If the control will not dock at the top of the display, right-click on the Preference column heading in the grid, then select Allow Docking from the context menu displayed. Now drag and drop the control to the top of the AutoCAD display area to dock it. The docked control will appear as shown below (imperial project illustrated).

ROUTING PIPE AND FITTINGS LINE L1000


LINE L1000

Create a zoom window around the horizontal vessel as shown below. Be sure to leave enough room to route pipe and fittings on the South end of the vessel. You will begin by attaching a weldneck flange to the nozzle on the West end of the vessel, then place an away-facing elbow four-feet from the end of the flange. Connecting pipe will then be placed between the two fittings.

West NozzleL1000

East NozzleL2000

Zoom around the horizontal vessel as shown. Throughout this tutorial, we refer to the “West” and “East” nozzles.

> CONNECT A FLANGE TO THE WEST NOZZLE

1. As noted previously, values for project objects LineNumber, Area, Unit, and Service must be set prior to placing a component in PIPING. An exception to this rule is when you are connecting to an existing component and have the Drawing Preferences Data Mode set to From Connecting Component. In this instance, PIPING will read the values for these objects from the connecting component automatically. However, when connecting to an existing EQUIPMENT component, only the LineNumber project object value can be determined from the EQUIPMENT nozzle, therefore, you must still set values for the remaining project objects. From the Component Preferences minibar, set the project object and drawing preference values as shown below.



2. To connect a weldneck flange to the west nozzle, select Piping > Flanges > Weldneck. The prompt

Current elevation <COP 0"> Elevation/<Pick point>:

displays. Select any point on the face of the West nozzle. As long as a point is selected near the outline of the nozzle, PIPING will automatically recognize that you want to connect to the end of it.

3. The prompt

Current elevation <COP 0"> Relative/Elev/<Pick point or Return for fit-fit>:

displays. Press Enter to place the flange using the “fitting-to-fitting” method. The flange will be placed as shown below.

In the following procedure, you will use the Relative placement option to place an elbow, 4-feet {1200mm} south of the flange.



> PLACE AN AWAY-FACING ELBOW 4’ {1200MM} FROM THE FLANGE


2. A reference point displays at the end of the flange to indicate where the default placement point is located. Normally, you could simply press Enter to connect the two components using the “fitting-to-fitting” method. However, in this exercise you want to place the elbow 4-feet {1200mm} away from (relative to) the end of the flange. The prompt

Relative/Elev/<Pick point or Return for fit-fit)>:

displays. Press the Relative button on the Responses toolbar, or type R and press Enter. The prompt changes to read

Align/change Ref point/<Enter distance or Return for fit-fit>:

Type 4’ {1200} at the command line then press Enter.

3. An outline of the elbow is drawn four-feet {1200mm} away from the flange, and the prompt


displays. Note that the reference point appears on the center of the elbow. Press Enter to accept the default center-point insertion.

4. The prompt

Enter orientation:

displays. Press the -Z button on the Direction Aids toolbar to specify that the opposite leg of the elbow moves in the -Z direction. Press Enter to complete the elbow placement as shown in the following figure.

4’{1200mm}



> PLACE PIPE BETWEEN THE FLANGE AND THE ELBOW

Now that you have connected the flange to the nozzle and placed the elbow, you will connect pipe between the two components. In this step, the Connect To command will be demonstrated.

1. Select Piping > Pipe Components > Pipe.

2. The prompt

Relative/Toggle/create taP/Elev/<Pick point or Return for fit-fit)>:

displays. Notice that the default reference point is the end of the elbow that points toward the flange. Press Enter to accept this point as the reference point and connect to it.

3. The prompt


displays. Type C and then press Enter.

4. The prompt

Select component:

displays. Pick the open end of the flange. Connecting pipe is placed between the two components as shown in the following figure.

Select the open end of theflange when the “Connectto” prompt is displayed.

Hint In this example, pipe was placed between two existing components. A separate command, AutoPipe, is available for placing connecting pipe between several components. This feature will be demonstrated later in this chapter.



LINE L2000

The nozzle on the east end of the horizontal vessel is the starting point for line L2000. In this exercise you will turn ON the Auto Router toggle switch, then add a valve/flange assembly to the nozzle. Afterwards you will copy the away-facing elbow placed earlier and assign it to this line.

Note The east nozzle was assigned the Line Number L2000 when it was placed on the vessel in AutoPLANT EQUIPMENT. Since the From Connecting Component option is enabled in the Drawing Preferences dialog, the line number will be automatically reset once you attach a component to this nozzle.

> ATTACH THE VALVE

1. Select Piping > Valves > Gate > Gate.

2. The prompt

Elevation/Insert/<Pick point>:

displays. Since you are not continuing to route off the last component (the away-facing elbow on line L1000), you must specify a new reference point. Pick the open face of the east nozzle.

3. The prompt

Relative/Elev/<Pick point or Return for fit-fit)>:

displays. The reference point symbol is now centered on the east nozzle. Press Enter to accept the fitting-to-fitting designation and attach the gate valve at this location.

4. Select the first gate valve record from the Specification Selection dialog then press OK. The AutoPLANT Selections dialog displays to enable you to connect an operator to the valve. Press Cancel for no topworks. The valve will be placed as shown in the following figure.

5. All of the components placed in the model to this point were inserted without using the Auto Router. To enable this function, select Piping > Setup > Drawing Preferences…. Enable the Auto Router Mode check box, and then press OK to close the dialog.

6. Attach a flange to the valve by selecting Piping > Flanges > Weldneck. Notice that you are not prompted to pick or accept the default insertion point at the end of the gate valve just placed.



With the Auto Router switch enabled, PIPING automatically assumes that you want to connect to the endpoint of the last component. The flange is placed with no further input from the user as shown in the following figure.

Note Enabling the Auto Router will only require additional input from the user during placement if there are more than one record for a component in the spec, or if a branching component is being inserted. In the case of the branching component insertion, you will be prompted to specify the branch direction before continuing to route components.

7. Select Piping > Setup > Drawing Preferences…, disable the Auto Router switch, then press OK to close the dialog.



COPYING COMPONENTS

PIPING components can be copied, moved, mirrored, or arrayed just like any other AutoCAD entity. When components are copied, a separate database record is created for each component. A dialog also displays to enable you to change/revise the line number drawing database field values for the copied components. In the tutorial model, the two nozzle centerlines are 6-feet (72”) {1800mm}apart. Since this design calls for away-facing elbows equidistant from the vessel shell, you can use AutoCAD’s COPY command to copy the existing elbow.

> TO COPY THE ELBOW

1. Type COPY at the command line and press Enter.

Warning Do NOT use AutoCAD’s Edit/Copy command or its associated icon on the AutoCAD toolbar. These commands are members of the COPYCLIP family, and are related to Object Linking and Embedding (OLE) functions. OLE operations are not supported in the current version of PIPING.

2. The prompt

Select objects

displays. Pick the away-facing elbow on line L1000 and then press Enter.

3. The prompt

Specify base point or displacement, or [Multiple]

displays. Pick any point near the elbow.

4. The prompt

Specify second point of displacement or <use first point as displacement>:

displays. Type @6’<0 {@1800<0} at the command line, then press Enter. The copied elbow is placed six-feet {1800mm} in the +X direction from the selected elbow as shown in the following figure.

5. The message

Rebis post-copy/explode component update in progress… Retrieving copied components... Updating database links... Re-establishing connectivity... Updating component data...

displays on the command line, and the following dialog displays to enable you to change the LineNumber project database value for the copied elbow.

Since the copied elbow will actually be part of LineNumber L2000, select L2000 from the Edit Value list as shown above, then press OK. The elbow is placed and associated with LineNumber L2000.

6. Finally, you will place connecting pipe between the flange and the elbow using the same technique you learned earlier. Select Piping > Pipe Components > Pipe.

7. The prompt:

Current elevation <COP 0"> Relative/Toggle/create taP/Elev/<Pick point or Return for fit-fit>:

displays. Pick the elbow and toggle to the open end that lies in XY Plane facing the flange, then press Enter.

8. The prompt

Connect To/<Enter Length>:

fsdisplays. Type C and press Enter, and then pick the open end of the flange. The model appears as shown in the following figure.



WORKING WITH REFERENCE POINTS

In this exercise you will route from an isometric view of the model, and learn other methods of placing components relative to one another. Of particular note in this exercise is the capability to automatically align a single component with others that have already been placed.

1. Change the viewpoint in order to get a better working view of the model. Press the SW Isometric View button (or type vpoint -1,-1,1 at the command line), then zoom around the horizontal vessel to obtain a view similar to that shown below.

Select a point on the end ofthis elbow to begin routing




3. The prompt

Current elevation <COP 0"> Elevation/Insert/<Pick point>:

displays. Pick the open end of the elbow on Line L1000 as shown in the Figure above. A reference point is placed on the end of the elbow and the prompt

Current elevation <COP 0"> Relative/Elev/<Pick point or Return for fit-fit>:

displays. Type R(elative), then press Enter.

4. The prompt

Align/change Ref point/Elev/<Enter distance or Return for fit-fit>:

displays. Note that the reference point now becomes the center of the elbow. PIPING assumes that you want to use the center point as the reference (when needed, you can change the reference point using the change Ref point option). Type E and press Enter to display the Set Elevation dialog shown in the following figure.

Enable the Center of Pipe radio button, then type 2’ {600} in the Elevation field and press OK to insert the elbow at an elevation of 2-feet {600} relative to the selected elbow.

5. The prompt


displays. Press Enter to accept the default and insert the elbow at its center point.

6. The prompt


displays. Press the +X direction button on the Direction Aids toolbar to set the orientation. Press Enter to complete the placement as shown in the following figure.



4’

Elev: 2’



THE ALIGN TO OPTION

In this exercise, you will place a tee at a point directly below the away-facing elbow on line L2000, which will also align with the centerline of the elbow that you just placed. This section will demonstrate the powerful Align To feature in PIPING, which enables a component to be placed so that it aligns with two existing components, even if those components lie at different planes and elevations.

> TO ALIGN A TEE

1. Select Piping > Branching Components > Straight Tee.

2. The prompt

Relative/Toggle/Elev/<Pick point or Return for fit-fit>:

displays. Use the Toggle option to toggle to the horizontal port of the elbow placed above (point PT1 in the following Figure).

PT1In Step 2, select the end ofthe elbow that runs in thehorizontal plane.

PT2In Step 5, select the openend of the elbow that turnsdown on line 102A.

3. The prompt


displays. Press the Relative button on the Responses toolbar (or type R then press Enter).

4. The prompt

Toggle/Align/change Ref point/<Enter Distance or Return for fit-fit>:

displays. In this example, you want the tee’s branch to align with the elbow on line L2000. Press the Align button on the Responses toolbar (or type A(lign) and press Enter).



5. The prompt

Pick component to align to:

displays. Select the away-facing elbow on line L2000 (point PT2 in the Figure above).

6. The prompt

Toggle/<Enter to select currently highlighted port>:

displays. The reference point symbols are imposed on the selected objects. Press Enter to insert the tee at the intersection of the selected component’s centerline paths.

7. An outline of the tee is placed in the model, and the prompt


displays. Press Enter to insert the tee at its center point.

8. The prompt


displays. Branching components have more than one alignment port as illustrated below. For example, the tee could be oriented vertically or horizontally and still align with the selected components. Press Enter to accept the default and orient the tee with its branch aligned with the elbow above it, and its run direction in the X plane.

The two alignment ports which can be associated with thetee are shown here. The next step is to orient the branch.

9. The last step determines how the branch is oriented. Press the +Z button on the Direction Aids toolbar, then press Enter to set this orientation and place the tee as shown.



CONNECTING PIPE

Earlier in this chapter, you used the Connect To placement option to connect two components that were placed in the same plane. In this section, the PIPING's AutoPipe command will be used to place connecting pipe between all of the “floating” components in the model.

> TO PLACE CONNECTING PIPE

1. Select Piping > Pipe Components > AutoPipe.

2. When the AutoPLANT Selections dialog displays, click on the Drawing tab as shown below. This dialog enables you to define a selection set of components via a number of options. The All option performs the operation on all components in the model, the Manual option enables you to select components individually, and the Advanced option expands the dialog to create a selection set based on a user defined query. This utility will be covered in more detail later in this tutorial. Enable the All radio button then press OK.

Connecting pipe is automatically placed between all open-ended components that have another component with an open end lying in the same plane as shown in the following Figure.

Connecting pipeis not placed

This tee belongsto L1000

This elbowbelongs to L2000



3. Notice that connecting pipe was not placed between the downward turning elbow and the tee. This is because the elbow belongs to LineNumber L2000 while the tee belongs to LineNumber L1000. AutoPIPE will not automatically resolve differences in these values. This prevents faulty assignment of line number identifiers. Select Piping > Pipe Components > Pipe.

4. The prompt

Current elevation <COP 2'> create taP/Elevation/Insert/<Pick point>:

displays. The first component you pick in this step determines the line number assigned to the pipe. If you pick the elbow, the pipe will be assigned to line L2000. If you pick the tee, the pipe will be assigned to L1000. Select a point on the open end of the elbow.

Note In Chapter 6, The Drawing Database, you will learn how to edit the line number assigned to a component.

5. The prompt

Relative/create taP/Elev/<Pick point or Return for fit-fit>:

display. Press Enter to connect to the elbow.

6. The prompt


displays. Type C and press Enter, then select a point on the branch of the tee. The model appears as shown below.



ROUTING A CENTERLINE

Another method of component placement involves routing a centerline to define the piping path, then placing components directly on the line to ensure proper alignment. This method has the advantage of laying out the entire pipe run at the outset.

A centerline in PIPING may be intelligent, meaning that the application can read the positional data stored on these lines to insert components. Preferences can also be saved with the line and automatically applied to any components placed on it. In this section, you will route a centerline to connect the open end of the tee with the nozzle on the vertical vessel. Afterwards, you will add elbows at the intersections and then use the AutoPipe feature to complete the model.

> TO ROUTE A CENTERLINE

1. Change the display view so that both the end of the tee and the nozzle on the vertical vessel display as shown in the following Figure.

2. Attach a gasket and flange to the nozzle on the vertical vessel. Select Piping > Flanges > Weldneck.

3. The prompt

Elevation/Insert/<Pick point>:

displays. Select the open end of the nozzle on the vertical vessel, then press Enter to attach the flange, gasket, and bolts to the nozzle at the reference point as shown in the following figure.



4. Select Piping > Piping Tools > Centerline Routers > From Dialog.

5. The Router Line Info dialog displays as shown below. The Info Mode determines the polyline’s degree of intelligence. Enable the Info Mode On radio button, then press OK.

6. The Centerline Preferences dialog displays as shown below. This dialog enables you to define preferences that will be stored with the line and applied to all components that are placed on the line. When you click in the Line Number field, a list of LineNumber values that have been defined in the project will appear in a selection list. This list is filtered based on what you type in the Line Number field in this dialog (e.g., type L1 to show all LineNumber values starting with L1). Set the dialog values as shown below, then press OK.



7. The prompt

Exit/<Options>/Start Point:

displays. Type END and press Enter, then select the end of the flange connected to the vertical vessel’s nozzle. The Router will automatically extract the elevation parameters from that point.

The prompt


displays. This prompt enables you to change the port of the flange that was picked above. If the port on the open end of the flange is selected, press Enter, or if it is not, type T until it is selected.

8. The prompt

Exit/<Options>/Pick Point:

displays. You can either input points directly from the command line using standard AutoCAD techniques, or press Enter to open a dialog of options. In this instance, use the command line: Type @2’<135 {@600<135} and then press Enter. A line is drawn 2-feet {600mm} from the end of the flange.

9. Press Enter to open the Routing dialog shown below.

Select Box Router Pick from the Options section of the dialog, then press OK. The Box Router Pick option will draw a temporary box between the current point and a user-selected point. This makes it a simple matter to route 90-degree changes in direction between two points which lie at different elevations.

10. The prompt

Pick End Point of Box:

displays. Type END and press Enter, then pick the end of the tee as shown in the following figure.



Select the endpoint on the tee as thereference point.

11. The prompt


displays. Make sure that you have selected the open end of the tee as shown above, then press. You can type T to toggle to this end if required.

12. A temporary box is placed on the screen between the selected points. The prompt

Exit/Connect/Redraw Box/Points/Slope/Increment/Auto/Keep/<Next>:

displays. Type A and then press Enter. The Automatic option will offer suggested routes between the two points.

13. The prompt

Exit/Redraw Box/Manual/Keep/<Next>:

displays. Note that a yellow line is routed between opposite corners of the box. Press Enter to accept the <Next> option and cycle through the available paths until the route shown in the following figure displays.

14. Type K and press Enter to accept (<Keep>) the highlighted centerline path. The centerline is routed between the selected points.



15. The prompt

Exit/<Options>/Pick Point: E

displays. Type E then press Enter to exit the router. The drawing appears as shown below.

ADDING ELBOWS AT THE INTERSECTIONS

Now that you have routed a centerline, you can use its intelligence to place elbows at each of the intersections. In this exercise, the intersections where elbows will be placed are referred to by the numbers shown in the following figure.

> TO ADD THE ELBOWS


2. The prompt

Relative/Elev/<Pick point or Return for fit-fit>:

displays. Select a point near Intersection 1 to place the elbow. Notice that you were not required to specify the direction or the orientation because this information was extracted from the geometry of the centerline.

3. In PIPING you can always repeat the last command by simply pressing Enter (or the right mouse button). Press Enter to place another elbow. The prompt


displays. Select a point near Intersection 2 to place the second elbow.

4. Press Enter to re-execute the elbow command, then select a point near Intersection 3 to place the third elbow. The elbows are placed on the centerline as shown in the following figure.



COMPLETING THE MODEL

In this section, you will complete the tutorial model by placing connecting pipe between the fittings on the centerline.

> TO FINISH THE MODEL

1. Select Piping > Pipe Components > AutoPipe to display the AutoPLANT Selections dialog.

2. Click on the Drawing tab then enable the All radio button and press OK.

3. Connecting pipe is placed at the proper locations as shown in the figure below.

4. Use AutoCAD’s Zoom All command to get a better look at the model. Select Piping > Piping Tools > Display Modes > Set Wirefame, then type HIDE and press Enter to display the model as shown in the following figure.

ROUTING PIPE AND FITTINGS SAVING THE DRAWING


SAVING THE DRAWING

Select File > Save to save the model. If you examine the directory containing the PIPE_TUTOR.DWG {PIPEM_TUTOR.DWG} file, you will note that there is also a file named PIPE_TUTOR.MDB {PIPEM_TUTOR.MDB}. This is the MS-Access formatted external drawing database file created when working in a Distributed Mode project. You will be working with database information in the next chapter.

CHAPTER REVIEW

The following important features and/or concepts were introduced in this chapter.

+ Specification Selection: If more than one valid record exists in the current specification, a dialog displays to enable you to choose the desired component.

+ Relative Placement: The Relative placement option allows components to be placed a given distance away from an existing component. Toggle options are available to place the component with respect to its centerpoint or endpoint.

+ Copying Components: PIPING components can be copied just like any other AutoCAD entity. Separate records are created in the drawing database, and the user is prompted to (optionally) change the line number associated with the copied component.

+ Align To: The Align to option (available when placing components using the Relative command) enables you to place bends or branching components so that the centerlines are aligned with the centerlines of selected components.

+ AutoPipe: The AutoPipe feature automatically places connecting pipe between selected components.

+ Centerline: The Router dialog contains options for drawing centerlines. After a piping path is defined, components can be placed directly on it to ensure proper connectivity and elevation settings. If the router is initiated with Info Mode set to ON, component preferences defined when the line was drawn are applied to any component placed on it.

WHAT’S NEXT?

In the next chapter, you will explore the commands associated with viewing and editing the external drawing database information. You will add a tag value to a valve, view the database record, and learn how to clean the external drawing database so that it accurately reflects the components contained in a model.


DATABASE FUNCTIONS

PIPING creates intelligent models. There is a dynamic link between the components in the model and the associated records in the external project database. You can query this data to produce reports or to modify the records. This chapter introduces you to some of PIPING’s database manipulation and editing tools.

DATABASE FUNCTIONS OVERVIEW


OVERVIEW

This chapter demonstrates two (2) database edit methods. The first involves the simple modification of a single component; the second method involves updating the attributes of several components simultaneously. In addition, you will learn how to clean the drawing database to ensure that the records in the database are synchronized with the components in the model.

First, an overview of how data is stored in the external database based on project mode will be discussed.

PROJECT MODE

When a component is placed in a PIPING model, a record is written to an external database. The manner in which this data is stored is dependent on the project mode selected when the project was created. A description of this process is provided below for each project mode.

STANDALONE MODE

If working in Standalone Mode, all data will reside in an external MS Access (*.MDB) drawing database. In this mode no project effectively exists. In reality, all project data that would normally exist in the project database will reside in the drawing’s MDB. Therefore, it is very much like the running in Central Mode, except that only the individual document exists in the project.

If working in Standalone Mode, each drawing will have its own associated drawing database (drawing_name.MDB). There will be multiple tables in this single drawing database file. The primary table for PIPING component information is the PIPING table. Relationship data, such as which components exist in a particular Area or on a particular LineNumber, is stored in the drawing database.

Working in this mode limits your ability to perform operations on multiple drawings, since access to the drawing database is only available for the individual drawing (since it is the only drawing in this standalone “project’). For example, you cannot select multiple drawings to generate reports.

DISTRIBUTED MODE

Distributed Mode is similar to the method used to store data in AutoPLANT v2.01. Like standalone mode, the drawing and its associated database exist as separate files. However, the drawing is part of a project, where all project specific data (e.g., relationships, etc.) are stored in that project database (PROJDATA.MDB).

In addition, a record for each document in the project will exist in the project’s document register (DOC_REG table in PROJDATA.MDB). Bentley AutoPLANT functions (e.g., report generation, Auto-Iso, etc), may be performed on a selection set of drawings that exist in the project. The relationships that are now established by working in a true project environment enable AutoPLANT to now provide options in the selections tool, which enable you to quickly select, for

DATABASE FUNCTIONS PROJECT MODE


example, all components in all drawings in a project that have the same LineNumber, Area, Service, or Unit.

The PIPING table will still exist in the drawing’s database, but relationship data will be stored in the project’s PROJDATA.MDB database. This enables you to execute AutoPLANT commands that perform queries across all project data.

CENTRAL MODE

Central Mode may only be setup for MSDE, SQL Server, and Oracle database configurations. If running in Central mode, all data for all drawings in a project will reside in a central project database. No individual drawing database will exist. Central mode and/or SQL Server and Oracle is an additional cost item.

Note A separate guide, Project Administrator’s Guide is provided with your software that describes project setup and configuration in detail. This document is provided in Adobe Acrobat PDF format and may be launched via the Bentley > Plant > Tutorials > Project Administrators’ Guide selection in your Windows Start menu. You must have Adobe Acrobat Reader v4.0 or later installed to view/print this document.

DATABASE FUNCTIONS VIEWING COMPONENT INFORMATION


VIEWING COMPONENT INFORMATION

In this section, you will examine the database records for the gate valve shown below. If you have closed the drawing from the previous chapter, re-open it now and zoom in to the area of the model shown below.

By simply pausing the cursor over the gate valve, some basic component information will display in the drawing as shown in the figure. However, in the following exercises, you will view and edit additional database information for the valve using the Edit Component command.

> TO VIEW COMPONENT INFORMATION (PAGE 1)

1. Select Piping > Database Tools > Edit Component. The prompt

Select the component, press return when done:

displays. Pick any point on the outline of the gate valve to display Page 1 of the Valve Information dialog as shown below.

Note You can also double-click on the valve to display the dialog.



(Imperial Version of Dialog)

Separate Component Information dialogs are provided for most component types. These are defined in the component script files that reside in your ..\MODULES\BASE\COMMON network directory. Each dialog displays the General Information from the database in the top area of the dialog, and the Class Information in the bottom area. The tile window at the top right of the dialog displays an illustration of the component type and the points where ports are located. Ports are points that contain connection and vector data as you will see in Page 2 of this dialog.



> TO VIEW COMPONENT INFORMATION (PAGE 2)

1. Press the Next Page button at the bottom of the dialog.

2. Page 2 of the Component Information dialog displays as shown below.

(Imperial Version of Dialog)

This dialog is divided into two sections. The top list box displays port information. The coordinates for the ports are listed along with the vector information that defines the run direction of the component. The Main Size, End Condition, Facing, and Pressure Class associated with the ports are also listed.

The bottom text box lists all of the component’s drawing database fields and their values. You can select an item in the bottom list box to edit its value. If an item is not editable, a warning message will be issued indicating that the field is READ-ONLY.

DATABASE FUNCTIONS EDITING COMPONENT INFORMATION


EDITING COMPONENT INFORMATION

The following procedure explains how to enter a new Tag field value for the valve and save it to the component record. In the next chapter, you will place this value as annotation.

> TO EDIT THE VALVE’S COMPONENT INFORMATION

1. Press First Page to return to the first page of the dialog.

2. Press the Create Tag button to display the New Tag dialog shown below.

3. As you can see from this dialog the tag format for a gate valve has been defined to consist of two parts, Code and Num. From the first page of the Valve Information dialog, type A2R in the Code field and 1 in the Num field, then press OK to close the dialog.

4. Notice that the Tag just entered now appears in the Valve Information dialog.

5. Press OK to close the dialog. The prompt

Select the component, press return when done:

displays. This command automatically remains active until it is terminated. Select the valve again to re-display the dialog. Note that the new tag value has been saved in the component database record.

6. Press OK to close the dialog then press Enter to terminate the Edit Component command.

Warning Exercise extreme caution when using a database editor to edit component records directly. We recommend using the Edit Component or Update Component commands to edit values, as doing so will ensure compatibility with other operations of the program. When using an editor, do NOT edit values that provide dimensional information about the component. You should also not modify project object values manually.

DATABASE FUNCTIONS VIEWING THE DRAWING DATABASE


VIEWING THE DRAWING DATABASE

The View Database command enables you to view all or selected component records in the external drawing database in a dialog within the PIPING application.

> TO VIEW THE DRAWING DATABASE

1. Select Piping > Database Tools > View Database… to display the AutoPLANT Selections dialog. Click on the Drawing tab then enable the All radio button and press OK.

2. After creating your selection set, the Database View dialog displays as shown below. Use the scroll bar to view the entire list of component records (Imperial project shown below).

(Imperial Version of Dialog is Shown)

Hint You can select a record in this dialog and press the Go To button to zoom into the selected component and center it within the display, or press the Edit button to execute the Database Tools > Edit Component function on the component.

3. Press Cancel to close the dialog.

DATABASE FUNCTIONS UPDATING COMPONENTS


UPDATING COMPONENTS

Bentley AutoPLANT applications make extensive use of databases to track and manage component data. This includes the use of specification databases to extract the parametric data used to draw components, as well as a project and drawing databases to store component information (based on the project mode you have selected). By storing component information in an external database, a high level of control can be maintained over the components in a drawing.

For example, an engineer may determine that the pressure rating of a given line must be upgraded because of the demands of the system, or that the material of a given line should be changed from carbon steel to stainless. The Update Component function enables you to create a selection set of components that match user-defined criteria, then to specify a new value for a selected database field and apply that value to update the drawing database records for all selected components.

Changes can be made to component records in the current drawing, or to component records in any number of drawings that belong to the same project. The selection tool has also been upgraded for this release to support the manner in which data is stored for the new project relationship objects (e.g., LineNumber, Area, Unit, and Service). A new Project tab has been added to the tool’s interface to enable you to quickly create project-wide selections based on values for these relationships.

For example, you can now quickly select all components that reside in all drawings that exist in a project that have the same LineNumber project object value. The following example demonstrates how to create a selection set of components from the current drawing, and then update the LineNumber relationship value for every component in the selection set.

> TO REVISE A LINE NUMBER

1. Select Piping > Database Tools > Update Components… to display the AutoPLANT Selections dialog shown in the following figure.

2. This is the same dialog that appeared when you selected the AutoPipe command earlier in this tutorial. This selection dialog displays whenever a command may be applied to more than one component.



3. Enable the Advanced radio button to expand the dialog to create your search criteria. This option enables you to create a selection set of components based on a 3D Piping Data field value, specific project database relationship value, or on drawing attributes, such as Color or Layer. In this example, you will define a query to select all components in the model whose LineNumber project relationship value is L1000.

Hint Press the dialog’s Help button for a detailed explanation of every dialog option.

4. The right pane of the dialog will display a separate node for every drawing in the current project. If you want to include a drawing in the search, you should enable the check box to the left of that drawing in this list. The check box next to the current drawing is enabled by default.

5. The Query Selection area of the dialog enables you to select a query from those that have been previously defined, or were included with the shipping version of the software. Since you only want to apply this query to the current drawing and do not want to save it for future use, you can ignore the settings in Query Selection area of the dialog.

6. The Define Query area of the dialog is where you define the condition that will be used to select the component records. The Type field indicates the data type that you want to search. Since you want to base this search on the value of the project relationship object LineNumber, select Relationship.

7. The Attribute Field drop-down list will now list all project objects defined in the project. Select LineNumber from this list.



8. The Constraint field defines the relationship between the Attribute Field and its value. For example, you can specify that you want to search for all component records whose line number is equal to L1000 (LINENUMBER = L1000), or all component records whose line number is NOT L1000 (LINENUMBER != L1000). Select the equal “=” Constraint.

9. Specify the desired field value in the Attribute field. There are two methods available to specify the value: you can type it directly in the space provided, or select it from a list. Press the browse button (shown at left) to display the dialog shown in the following figure.

When Browse is pressed, PIPING will compile a list of unique values for the selected attribute. The Filter field enables you to filter the list of entries displayed in the dialog. For example, if you have a large drawing that contains hundreds of line numbers and only want to select from line numbers that begin with the characters L1, you can filter the display of line number entries in this dialog by entering L1* in the Filter field, then pressing Reselect. The "*" implies a wild card of any number of characters. Select L1000 then press OK.

10. The last step is to add the query to the active list, then execute the query. As each query is defined, you must add it to the Active Queries list. In this manner, you can construct a highly detailed search consisting of multiple queries in combination with the And and Or operators (refer to on-line help for more information). This example is a simple one: press Add-> to add the query to the Active Queries list as shown below.



11. Press OK to execute the query.

12. The Update Component dialog displays as shown in the following figure. In this example, you want to change the LineNumber relationship value for all components related to LineNumber L1000 to LineNumber L3000. Select L3000 from the Edit Value drop down list then press OK.

Note Remember, you added the LineNumber project relationship value L3000 to the project earlier in this Tutorial.

13. All components in the current drawing whose LineNumber project object value was previously related to L1000 are updated so they are now related to LineNumber L3000. All project



relationships have also been updated to indicate that these components now belong to LineNumber L3000.

To check the update, select Piping > Database Tools > Edit Component, then select one of the components previously belonging to L1000 (For example, any segment of pipe between the tee and the vertical vessel). Confirm that L3000 now appears in the Line No. field, then press OK to close the dialog. Press Enter to end the Edit Component command.

DATABASE FUNCTIONS CLEANING THE DATABASE


CLEANING THE DATABASE

As components are placed, the drawing database is continually updated. If a component is placed in the model and then later erased, the drawing database would contain a record for a component that no longer exists in the drawing. In order to ensure the database accurately reflects the current state of the model, you should clean the database periodically.

> TO CLEAN THE DATABASE

1. Select Piping > Database Tools > Clean Database to display the dialog shown below.

2. A brief description of each of these options is provided below.

NAME DESCRIPTION

Clean Database Records

Enable this check box to synchronize the external drawing database so that it will match the contents of the current drawing. Any database record that exists without a corresponding graphic component is removed.

Clean Fasteners

Enable this check box to remove both the CAD and external database entries for those fasteners that are no longer joining two components together. For example, if a weld is connecting a pipe and an elbow and the elbow is removed, the weld is left, unless also manually removed. This operation will clean up such fasteners.

Clean Graphics Data

On rare occasions a graphic component is created without a corresponding database record. This implies there is no intelligence associated with this component. Enable this check box to move those graphical components that exist without an associated database record to the piping_orphan layer.

This enables you to "quietly" clean the database. Current cleaning statistics are still reported to the command line, but the total information dialog will not be reported if this option is left unchecked. This enables an operator to request the clean operation and allow the entire process to be executed without interaction.

Enable all of the check boxes then press OK. Status messages will display on the command line to indicate changes to the drawing during this process.

DATABASE FUNCTIONS CHAPTER REVIEW


CHAPTER REVIEW

The following important features and concepts were introduced in this chapter.

+ Viewing Component Information: A component’s database information can be viewed directly with the Edit Component command. A two-page dialog will display general component information, port information, and a list of drawing database field values for the selected component.

+ Editing Component Information: Component data can be edited from the same Edit Component dialog. Editable fields can be distinguished as white text boxes in the dialog. Input the new value and press OK to update the record. If you attempt to modify a project object value in this dialog, a selection list of values available in the project will appear.

+ Viewing the Drawing Database: Component records in the drawing database can be viewed directly from within PIPING. Select Piping > Database Tools > View Database…. A dialog displays a list of component records in the database.

+ Updating Components: The Piping > Database Tools > Update Components… function can be used to update the value of a database field for a selection set of components. The update function can work in the current model, or may include any number of components that exist in the current project. The selection tool enables you to base your search criteria on project relationship object values, 3D Piping Data values, or drawing attribute values.

+ Cleaning the Database: As a drawing is constructed, records are written to the drawing database. If a component is erased from the model, a record still exists in the drawing database until it is removed using the Clean Database command. This command should be executed periodically to keep the drawing database synchronized with the model.

WHAT’S NEXT?

In the next chapter, you will learn how to use PIPING’s Drawing Production commands to setup tiled viewports in Layout View (Paper Space), then place dimensions and annotation text in the drawing. Bentley encourages the use of layouts (paper space) to perform these activities as it ensures the model will be kept clutter-free. It also helps to visualize how the final production plot will look and enables you to conveniently manipulate several views of your drawing in one environment.


DRAWING PRODUCTION

This chapter explains how production drawings are created from a PIPING model. The concept of a Work Area is explained, and two saved Work Area views are inserted into Paper Space. Each of these viewports is dimensioned and annotated to create a Plan and Sectional view of the model on the same drawing sheet.

DRAWING PRODUCTION OVERVIEW


OVERVIEW

This chapter introduces PIPING’s drawing production commands. Two key concepts: Work Space and Work Space Views, are discussed in detail. Two Work Space Views are defined and placed in Paper Space as a Plan and Sectional view. Later in the chapter, dimension and annotation tools are demonstrated. After completing these exercises, your drawing will look similar to the one shown below.

BEFORE YOU START

Before you begin these exercises, open the drawing created in the previous chapter. If you have not completed the model created in Chapter 5, return to that section of the tutorial and create it. You will be extracting the updated valve tag and line numbers assigned in Chapter 6, and placing these values as annotation.

DRAWING PRODUCTION SETTING UP PAPER SPACE


SETTING UP PAPER SPACE

Bentley encourages its users to dimension and annotate in Paper Space (Layout). For those of you unfamiliar with Paper Space, it provides an environment to construct several views of your drawing and place them on a virtual “sheet” of paper. To facilitate the use of Paper Space, drawing production tools have been provided, which make it easy to create and place single or multiple orthogonal projections of the model on the same drawing sheet. It is then a simple matter to add dimensions and annotation.

Another advantage of paper space is that it keeps the model clutter-free. You can place dimension lines, annotation, and Bill of Materials in paper space, without worrying about freezing these layers in order to view a “clean” representation of the model.

The remaining exercises in this chapter (and the next) rely on the use of Paper Space.

> TO SETUP PAPER SPACE

1. You should still have the PIPE_TUTOR.DWG {PIPEM_TUTOR.DWG} model open. Type PLAN and press Enter twice to view the entire model.

2. Move into Paper Space using one of the following methods:

+ Click on the Layout1 tab, or

+ Type tilemode 0 at the command line

The Page Setup dialog displays when you click on the Layout tab to enable you to setup the Layout’s plotter and paper size. Click on the Plot Device tab. For this tutorial, select the PublishToWeb DWF.pc3 plotter driver from the plotter Name list. This plotter driver provides the page size options required to complete this tutorial. Click on the Layout Settings tab, then select ANSI D (34.00 x 22.00 inches) from the Paper Size drop-down list. Metric users can use the ISO expand A2 (594mm x 420mm) paper size. Press OK to accept the plotter configuration. Type E and press Enter, then select a point on the border of the default viewport placed on the layout and press Enter to delete it. You will add viewports using AutoPLANT Drawing Production commands later in this exercise.

3. Select Piping > Drawing Production > Drawing Setup….

4. The prompt

Align/Create/Scale viewports/Workarea views/Options/Title block/Undo:

displays. Type T, then press Enter to insert a standard AutoCAD title block.

5. The prompt

Delete objects/Origin/Undo/<Insert title block>:

displays. Press Enter to display the title block selection dialog shown below.

DRAWING PRODUCTION SETTING UP PAPER SPACE


Note The title block drawings shown in this dialog are controlled by the current configuration. In the configuration you can define the directory used to display the available border drawings.

6. Select the dbord.dwg {a2bord} border file, then press OK. The Edit Attributes dialog displays as shown below. You can input the drawing name and file name in the fields provided to include them in attribute blocks in the border. Type PIPING TUTORIAL MODEL in the DOC_NAME field then press OK. The string entered in the DOC_NAME field will automatically be placed on the title block when it is inserted.

DRAWING PRODUCTION WORK AREA


7. The ANSI-D {ISO-A2} Size title block is placed as shown in the following figure. Press Enter to end the title block insertion command.

Note It may be necessary to use AutoCAD's Move command to re-position the title block so it is aligned correctly

8. To return to model space, click on the Model tab.

WORK AREA

Now that the title block has been placed in Paper Space, you can return to Model space to define the areas of the model that will be placed on the sheet.

WHAT IS A WORK AREA?

During the generation of plant models and drawings, it is frequently necessary to xreference drawings from a variety of disciplines. Xreferencing a drawing enables you to visualize how elements from various models will look when overlayed, and ensures proper connectivity among these elements.

For example, before placing piping elements, you might normally xreference steel and equipment drawings in order to ensure placement at the proper coordinates (i.e., connecting a flange directly to an xreferenced equipment nozzle). Similarly, drafters and designers from these other disciplines might need to xreference the piping drawing. The Drawing Production utilities drastically simplify this process by providing a mechanism to define a common Work Area. Individual drawings can be added to a Work Area in order to create a set of saved xreferenced drawings that overlay each other.



After the Work Area is defined, three-dimensional viewing cubes can be defined and associated. These views represent coordinates within the Plant Model which are shared by the set of referenced drawings. The view direction, scale, front and back clipping planes, etc. can also be saved with the view.

Step 2: Define the 3D Views (Clipping Planes) from the Work Area Views dialog.

View Area 2VV-IN

View Area 1HV-OUT = Named View with Front,

Back, and Elevation clipping

After the Views are created, they can be:

+ Applied: When in Model Space, an applied Work Area View is similar to a saved View Name that includes the set of referenced drawings. The result is a working view, which can be shared among all team members, or across multiple drawings.

+ Inserted: When in Paper Space, Work Area Views can be inserted as tiled viewports. Match lines and plant coordinates can be automatically placed along with the graphic, and users can



edit the orthogonal projection of the view. The ability to create and edit orthogonal views is useful in generating a variety of sectional views from the same Work Area.

Step 3: Place the named views in Paper Space or view them in Model Space

The Work Area tools are versatile and powerful. The next several exercises demonstrate how to create Work Areas, assign Views to the Work Area, and then how to place these views in Paper Space.



CREATING A WORK AREA

In this section, you will define a new Work Area. The file that is created by this process is a *.RWA file that can be saved on a local or a network drive. Drawings added to the Work Area as Members will be available to any other drawings that share the same Work Area. Drawings that join as Guests will xreference the specified set of drawings without becoming a permanent member of this group. Each of these concepts will be explained during the following procedure.

> TO CREATE A WORK SPACE

1. Select Piping > Drawing Production > Work Area Setup… to display the Work Area Setup dialog shown below.

2. Press New. A standard Windows file selection dialog displays as shown below. Navigate to the directory where your tutorial drawing file is stored (e.g., ..\TutorProject\IMPERIAL_TUTOR\Tutorial). Type TUTOR in the File name field, then press Save. The Work Area file is automatically saved with the .RWA extension.



3. The filename specified in the previous step now appears in the Work Area Setup title bar.

4. In the Title field, type TUTORIAL WORK AREA.

5. For this tutorial, the current drawing is the only one defined in the Work Area. Enable the Member radio button from the Membership Status area. Notice that the current drawing is immediately added to the list of referenced drawings. The Member Status determines the relationship between the current drawing and the Work Area’s referenced drawings as follows:

STATUS DESCRIPTION

Guest The current drawing is not added to the list of drawings associated with the Work Area. Joining as a Guest allows you to view how the current drawing is positioned in relation to the referenced drawings; however, your drawing will not be visible when this same Work Area is opened from one of the Member drawings.

Member The current drawing is permanently added to the list of referenced drawings, and will be visible when the Work Area is opened from one of the other Member drawings.

Non-Member

When this option is selected, the drawings in the Work Area are not visible inside the current drawing. Use this option to recall saved views or to place view ports in Paper Space using the coordinates associated with the selected Work Area (without including reference drawing information or graphics).

6. Notice that when a drawing in the Reference Drawings list is highlighted, the Insertion Point fields are enabled. This enables you to insert a drawing in the Work Area at specific coordinates. You can specify the coordinates manually. Use the Pick option to graphically designate the point, or accept the default origin (0,0,0). In this tutorial, you will accept the default.

Note The Reference Drawings area contains a list of the drawings associated with the Work Area. Files are added to this list by pressing Add and selecting the file. Drawings referenced in this way are linked to the current drawing using AutoCAD’s XREF/Overlay command (as opposed to XREF/Attach).

7. Press Save to save the Work Area definition, then press Done to close the dialog. The Work Area is now defined. Once the dialog is closed, the referenced drawings overlay the current drawing. In this example, since there is only one drawing, there are no xreferenced elements visible after closing the dialog.



DEFINING WORK AREA VIEWS

A set of views can be associated with a saved Work Area. In this section, two Work Area Views will be created: The first view is a top (plan) view of the entire model. The second is a front view section of lines L2000 and L3000.

> TO CREATE A PLAN VIEW

1. Select Piping > Drawing Production > Work Area Views….

Note If the Work Area Views command is selected and a Work Area has not been opened in the current drawing, you are prompted to select an RWA file. Otherwise, the dialog opens the last Work Area that was active.

2. The Work Area Views dialog displays as shown below.

3. Note that there are no views associated with this Work Area. Press Add from the Views group to define a new Work Area View.

4. The View Properties dialog displays as shown below. This dialog enables you to define a three-dimensional cube within the plant/model world. The coordinates are defined in the 3D Envelope area of the dialog. Once the cube is defined, you can specify the side (view) that will display in the Work Area View. The active projection is illustrated by a red box in the tile window. These views can be applied in Model Space, or placed as tiles in Paper Space.



5. In the View Title field, type AREA 1 - PLAN VIEW.

6. The View selection list determines the view direction. For example, after defining the geometry of the three-dimensional view (in the 3D Envelope area of the dialog), you must choose a side of the cube to view. Only orthogonal projections are permitted (Front, Back, Left, Right, Top, Bottom). Select Top to display the plan view.

Note The graphic on the left is updated based on the selected View. For example, if you select Front, the front side of the cube is highlighted in red.

7. Set the Scale to ½”=1’0” {1:30}. The scale applies when placing Work Area Views as tiled viewports in Paper Space.

8. The View Options are annotation and layer control options that are applied when the Work Area View is placed as a viewport in Paper Space. The Match Line setting draws a border around the viewport in Paper Space. The Coordinates display the plant world coordinates from which the view was “cut,” provided the Match Line option was enabled. The Clipping options exclude components (or parts of components) that do not lie within the boundaries of the 3D Envelope. The Viewport Visible option causes ALL AutoCAD viewport borders to become visible in the drawing. This option must be enabled if you want to be able to re-position viewports after they have been inserted. Make the following selections:

The View Options areonly applied to Work

Area Views placed inPaper Space

9. The next step is to specify the 3D Envelope settings. These points define the boundaries of the three-dimensional viewing cube. The First Point and Second Point fields determine the opposite corners of a box projected on the model from the plan. You can input these



coordinates manually, or interactively select them from the plan view of the model. The Elevation fields determine the Top and Bottom clipping planes, which define the height of the three-dimensional Work Area View. Input the following values:

First Point East 7’ {2100}

North 28’ {8500}

Second Point East 36’ {11085}

North 4’ {1240}

Hint You can pick these points manually by selecting the Pick View Area by Window option, then picking the window from the Plan view of the model. If you are creating a Top view, it is not necessary to specify elevation values. However, if you are creating a sectional view (Front, Left, Right, Back), you must specify Upper and Lower values to designate the height of the box. A sectional view is created later in this chapter.

10. Press OK to save the view and close the View Properties dialog. Changes to the view properties are saved automatically.

11. Control is restored to the Work Area Views dialog. Notice that AREA 1- PLAN VIEW is now listed in the window. Select the new view and press Preview.

12. The dialog temporarily closes, and a dashed red line is drawn around the defined view. Press Enter to return to the dialog. In the next section, you will create a Front View section.

> TO CREATE A FRONT SECTIONAL VIEW

1. From the Work Area Views dialog, press Add to display the View Properties dialog.

2. Type AREA 1 - FRONT VIEW in the View Title field.



3. From the View selection list, choose Front. Notice that the tile graphic to the left changes to indicate that a Front View projection has been selected.

4. Set the Scale to ¾”=1’ {1:20}.

5. Choose the following View Options:

Note The Coordinates option, which was not selected in the previous view, will annotate the plant coordinates of the projected view.

6. Input the following values to define the 3D View Envelope. Note that Elevation values are required for the Front View projection.

First Point East 11’ {3200}

North 23’ {6742}

Second Point East 28’ {8375}

North 12’ {3758}

Elevation Upper 8’6” {2580}

Lower 1’3” {450}

7. Press OK to close the View Properties dialog and add the front view to the Work Area.

8. Press Preview to confirm that the new view encloses the two pipe lines in the model.

9. Press Enter to return to the Work Area Views dialog, then press Close to exit. REGEN to remove the dashed view envelope.



PLACING WORK AREA VIEWS IN PAPER SPACE

In this section, you will place the two Work Area Views in Paper Space. Later in the chapter, the viewports will be dimensioned and annotated.

> TO PLACE VIEWS IN PAPER SPACE

1. Click on the Layout1 tab.

2. Select Piping > Drawing Production > Work Area Views….

3. Select AREA 1 - PLAN VIEW from the list, then press Insert in Drawing.

4. The dialog closes, a ghost image of the tile is anchored to the crosshairs, and the prompt

Insert point of viewport

displays. Select a point to locate the view as shown below, then click the right mouse button.

5. The plan view of the tutorial model is placed in Paper Space as shown below, and the Work Area Views dialog displays.

6. Select AREA 1 - FRONT VIEW then press Insert in Drawing.

7. The dialog closes, a ghost image of the tile is anchored to the crosshairs, and the prompt

Insert point of viewport

displays. Position the second viewport as shown below.



8. Press Close to exit.

9. Examine the drawing. Note the effect enabling the Coordinates option had on the second tile. Coordinates appear along the border of the viewport. These specify the East, West, and Elevation values from which the section was generated.

Note The size of the coordinate text is determined by the current value of AutoCAD’s DIMTXT system variable.

DRAWING PRODUCTION DIMENSIONS


DIMENSIONS

PIPING relies on AutoCAD for dimensioning tools. In general, you should refer to your AutoCAD documentation for instructions on using their dimension commands and the capabilities of these features. In this section, a few exercises are presented to illustrate the dimension placement process.

Note For users already accustomed to the use of Paper Space, you should be aware that we have defined the DIMLFAC environment variable. This variable sets a global scale factor for linear dimensioning measurements. All linear distances measured by dimensioning (including radii, diameters, and coordinates) are multiplied by the DIMLFAC setting before being converted to dimension text. This means that even though you will be selecting points from within paper space, the dimension values will reflect the distances in the model.

> TO PREPARE THE MODEL FOR DIMENSIONING

Before beginning these dimension exercises, establish the dimensioning and annotation preferences outlined below in the AutoCAD environment indicated.

1. Type DDIM and press Enter to display AutoCAD’s Dimension Style Manager dialog.

2. Press Modify to override the current settings.

3. On the Lines and Arrows tab, type 1/8” {3} in the Arrow size field.

4. Click on the Text tab, then type 1/8” {3} in the Text height field.

5. Click on the Primary Units tab. Ensure that the Unit format is set to Architectural {Decimal} and that the Fraction format is set to Horizontal. Set the Precision to 1/16” {0.00}.

6. Press OK, then press Close to exit.

You are now ready to dimension the drawing. The annotation settings were also established when you set the annotation text height.



> TO PLACE DIMENSIONS

1. Zoom Window around the boundaries of the first viewport as shown below.

2. The quickest method to execute AutoCAD’s dimensioning commands is through a toolbar. Select View > Toolbars… to display the Customize dialog. Enable the Dimension check-box to open the Dimension toolbar shown below then press Close to exit the dialog.

Hint You can either dock this toolbar to the perimeter of the screen or leave it floating, depending on your preference and working style.

3. Select Tools > Drafting Settings… to display the Drafting Settings dialog, then select the Snap and Grid tab and disable the Snap On check box to turn the snap mode OFF for this exercise. Press OK to exit the dialog.

4. Press the Linear Dimension button on the toolbar.

5. The prompt

4. The prompt

Specify second angle endpoint:



displays. With ORTHO ON[F8], select any point on the dimension line attached to the west end of the vertical vessel.

5. The prompt

Specify dimension arc line location (Mtext/Text/Angle):

displays, and a ghost image of the 45-degree angular dimension is centered on the crosshairs. Position it as shown below.

DRAWING PRODUCTION ANNOTATION


ANNOTATION

In this section, you will place annotation on the drawing. You will annotate the valve’s Main Size and Tag, and place Line Number annotation on the two lines running from the horizontal vessel. Like dimensions, annotation should be placed in Paper Space.

ESTABLISHING ANNOTATION PREFERENCES

Unlike dimensioning, a special set of annotation commands have been provided which are unique to the PIPING application. Annotation commands enable you to extract drawing database values and properties associated with a selected component and insert this information as text in the drawing. Preferences can be established so that annotation is placed with or without leader lines, drawn with a container around the text, associated with a block, etc. The method for controlling these preferences is the Annotation Preferences dialog, shown below. To open this dialog, select Piping > Annotation > Preferences….

Notice that when the dialog first opens, Default Settings is listed in the Annotation Style field. You can establish settings that are applied to all annotation types, or select a specific type from the Annotation Style list box to define properties unique to that type. In the first several exercises, you will be using the default values. Press OK to close the dialog. Later you will re-open this dialog to place rotated text as the default. (If using a Metric configuration, accept the default settings also).



VALVE ANNOTATION

In this section, you will annotate a valve’s main size and tag.

> TO ANNOTATE THE VALVE’S MAIN SIZE

1. Zoom into the area shown in the Figure below.

2. Select Piping > Annotation > Database Fields > Main Size. Notice that as soon as the annotation command is selected, the drawing switches to Model Space. This enables you to select the component in Model Space. When the annotation is placed, PIPING automatically switches back to Paper Space for the placement of the annotation.

3. The prompt

Select the component:

displays. Pick a point near the center of the gate valve.

4. The prompt

Annotation location:

displays. You can select multiple leaderline points to position the annotation. Pick a point to the right of the valve, then press Enter to complete the definition of the leader line and place the annotation as shown below.



5. The prompt

Format/Edit vertex/Rotate/Move/Annotation/eXit <X>:

displays. The placement prompts enable you to control how annotation is placed. You can rotate the text, format it, insert blocks, etc. Press Enter to complete the placement.

Hint If you prefer to place annotation without seeing this prompt, you can select another Placement Method from the Annotation Preferences dialog.

6. The prompt


displays. The annotation command is automatically repeated to enable you to place several instances of size annotation in your drawing. To end the command, press Enter.

Hint To exit the command immediately after placing annotation, choose a different Placement Method from the Annotation Preferences dialog.

> TO ANNOTATE THE COMPONENT TAG

In the previous chapter, you defined a valve tag using the Edit Component command. In this section, the Tag value will be extracted from the drawing database and placed as annotation.

1. Select Piping > Annotation > Tags > Component Tag. The prompt

Select component:

displays. Select the center of the gate valve.

2. A dialog displays showing the current Tag field value for the selected component. To accept the current value, A2R-1, press OK. The prompt


displays. You can select multiple leader line points to position the annotation. Pick a point to the left of the valve, then press Enter. Press Enter again to complete the definition of the leader



line and place the annotation as shown below. Press Enter, then press Enter to exit the command.

LINE NUMBER ANNOTATION

Now you will annotate the line numbers of the piping lines connected to the horizontal vessel. If you remember from previous exercises, the line on the west nozzle was revised from L1000 to L3000, while the line on the east nozzle remains L2000.

> TO CHANGE THE ANNOTATION PREFERENCES

1. Select Piping > Annotation > Preferences….

2. We’re going to revise the annotation preferences associated with line numbers. From the Annotation Style list box, select LineNo.

3. Type 90 in the Text Rotation field, then disable the following options:

+ Container

+ Hookline

+ Arrowhead

4. Set the remaining options as shown below, then press OK to save the new values and close the dialog. (For Metric configuration, set the Height to 3mm).





> TO ANNOTATE LINE NUMBERS

1. Zoom out to display both lines off the horizontal vessel as shown below.

Imperial

DRAWING PRODUCTION CHAPTER REVIEW


CHAPTER REVIEW

+ Working with Paper Space (Layouts): Paper Space is the recommended work environment for placing dimension lines and annotation text. It keeps the model clutter-free, and enables you to define and arrange several viewports on a single sheet for plotting.

+ Work Area Definition: A Work Area is a set of referenced drawings that share the same physical location in a plant layout. Members of the Work Area can view each others’ drawings and data. Guests of the Work Area can only view drawings that are permanent to the group. Work Area Views can be associated with Work Areas.

+ Work Area Views: A Work Area View is a three-dimensional cube that exists at defined coordinates that is specific to a saved Work Area. Members of the Work Area can apply saved views to their current drawings. In model space, this creates shared working views. Placing a Work Area View in Paper Space will ensure consistency in production drawing output among various members of a Work Area.

+ Dimensions: Dimensioning in Paper Space relies on AutoCAD’s dimensioning commands. After the Paper Space is properly configured, dimensioning is a simple matter of picking the points in the drawing between which dimension lines and distance text should be placed. The use of AutoCAD’s DIMLFAC command ensures there is a proper correspondence between paper space and model space units.

+ Annotation: Like dimensions, we encourage you to place annotation in Paper Space. When an annotation command is selected, the model will automatically switch into Model Space to enable you to select a component to annotate. An Annotation Preferences dialog enables you to specify whether or not leader lines are included, containers are placed around the text, and other variables that can be associated with individual annotation styles.

+ Creating a Section: In PIPING, a section is created by defining an Elevation Work View, then placing this view in Paper Space. Commands are available in the View Properties dialog to place coordinates along the boundary of the view. This helps to annotate the relative coordinates from which the section was created.

WHAT’S NEXT?

In the next chapter, you will remain in Paper Space to place a Bill of Materials. The options in the Bill of Materials dialog will be discussed, as well as the placement procedure.


GENERATING A BILL OF MATERIALS

In this chapter, you will learn how to generate a Bill of Materials and place it on the drawing sheet.

GENERATING A BILL OF MATERIALS OVERVIEW


OVERVIEW

Bentley AutoPLANT’s report function enables you to either generate a Bill of Materials (BOM) for placement on your drawing, or to generate external reports.

A Bill of Materials may be placed in either Model or Paper Space; however, as in previous chapters, the emphasis here will be on placing this report in Paper Space. This exercise demonstrates how to generate a standard BOM and place it on your drawing sheet. Other report options are available to generate reports that can be viewed on-screen, sent to a file, or sent to a printer. You can also generate equipment lists, nozzle schedules, and create customized reports. For more information on generating reports, refer to PIPING’s on-line help file.

Several options are available to generate the BOM, including the ability to ignore components marked as “existing” and to recalculate cutlengths. Formatting options are also available to control the appearance of the BOM. After you generate and place the Bill of Materials in this chapter, the drawing will appear as shown below.

Note Before beginning these exercises, you should have completed all exercises in the previous chapters.

GENERATING A BILL OF MATERIALS GENERATING THE BILL OF MATERIALS


GENERATING THE BILL OF MATERIALS

In this section, a Bill of Materials will be generated from your tutorial model. PIPING makes BOM placement easy. After the command is selected, PIPING examines the drawing database and compiles a list of the piping components in the model. You are then prompted to select a placement point.

> TO GENERATE THE BOM

1. Select Piping > Reports > Bill of Materials….

2. The Bill of Materials dialog displays. This dialog provides access to Bill of Materials reporting and configuration options. Select CAD Standard from the Report drop-down list then set the remaining dialog values as shown.



Descriptions of these options are provided below:

FIELD DESCRIPTION

Report Select the desired report type. For PIPING and ISOMETRICS, available reports are as follows:

CAD Standard: BOM with accumulated cutlengths for insertion in the drawing.

CAD CutLengths: BOM with individual cutlengths for insertion in the drawing.

CAD Maintenance: BOM with individual cutlengths and all other components listed individually.

CAD Rounded: BOM that will round up cutlengths to the nearest foot or meter.

CAD CutLengths Shop/Field: BOM with individual cutlengths with components sorted according to Shop/Field designations.

CAD Cutlengths Only: BOM including only individual cut lengths only.

CAD Spool Cutlengths Only: BOM including only individual spool cut lengths.

CAD Spool: BOM with individual spool cut lengths.

CAD Total: BOM with accumulated cutlengths and weight.

CAD Weight: BOM with accumulated weights for each component type.

CAD Shop/Field Total: BOM that splits shop and field components.

Report File Displays the file name associated with the selected Report Type.

Units The units reported on the Bill of Materials. The BOM units can be different than the units in the current drawing. The choices are Metric, Imperial, and Mixed Metric.

Precision Select the level of numeric precision reported for pipe lengths.

Suppress 0 Feet/Inches

These options are read-only, and display the settings as set for by AutoCAD’s DIMZIN environment variable. Only the imperial (architectural) settings are currently honored. Refer to your AutoCAD documentation for more information.

Bore Precision Assigns the precision of the display of the bolt nominal size.

Omit Codes When you place an AutoPLANT component the SORT_CODE value from its spec record is written to its drawing database record (e.g., SORT_CODE=17 for pipe, and SORT_CODE=1 for Weldneck Flange). This value controls whether components will be omitted from B.O.M. processing. Components whose sort order code is greater than this value will be omitted from the BOM.



FIELD DESCRIPTION

Ignore Existing Components

PIPING components can be marked as Existing using the Edit Component command to distinguish components that already exist in the field, and those that are part of a new design or revision. You may then update the drawings associated with a particular system, and generate a Bill of Materials that contains only those components that did not previously exist.

Enable the Ignore Existing Components field to omit components marked as Existing from the BOM.

Clean Database Fasteners

This option removes those fasteners that are no longer used for connecting components. For example if a pipe is welded to an elbow and the elbow is removed but the weld is left, this action will remove the weld from the pipe.

Append Pipe End Preparations

Specifies whether or not Pipe End Preparations will be appended to the Pipe Description in the BOM.

Append Topwork Descriptions

Specifies whether or not Topwork Descriptions will be appended to Valve Descriptions in the BOM.

Ascending SORT_CODE Order

If this check box is disabled, then the BOM records are sorted from largest to smallest component SORT_CODE value. If this check box is enabled, the records are sorted smallest to largest component SORT_CODE value.

Material Tag Options: When the BOM executes in PIPING it will update the necessary material tag fields according to the selection made. However, material tag balloon annotation will only be placed in ISOMETRICS/AUTO-ISO. When tagging attempts to create balloons for the tags in a PIPING drawing a warning message is issued, indicating that the material database tags have been updated only (no graphics will be generated). If you want to place material balloon tags in a PIPING drawing after a BOM has been generated, you may do so using the new Annotation > Tags > Material Tags command.

Tag Format This option enables you to specify how the material balloon tags are formatted. Two options are available.

Starting Tag Number This field enables you to specify the starting tag number for material tag placement and numbering.

No Material Tags Enable this option to disable the placement of material tags on each component. Enabling this radio button will automatically disable the associated Show Material Tags, Fastener Tags, and Support Tags options.

Update Material Tags Enable this option to update the MAT_MARK field with the new material tag for component records in the external drawing database.

Reinsert Material Tags This option is disabled in PIPING, and applied to ISOMETRICS drawings only. Enable this option to automatically update existing material balloon tags that may have been placed from a previous BOM run.

Do Not Update Existing Material Tags

This option is disabled in PIPING, and applied to ISOMETRICS drawings only. Enable this option to leave the existing tags and use them in the BOM, then only generate and place material tags for new items that were not tagged from the previous BOM run.



FIELD DESCRIPTION

Show Material Tags Show Support Tags Show Fastener Tags

The Show Material Tags option is only available when generating a BOM with AutoPLANT ISOMETRICS or AUTO-ISO. If enabled, the system will attach a material balloon tag to each component in the report selection set. This technique makes it easy to pair components in the drawing with records in the report. If this check box is enabled, the Show Fastener Tags and Show Support Tags option will also be made available to enable you to optionally display tags for supports and fasteners. (These options are disabled in PIPING)

3. Press Options to display the Bill of Materials configuration dialog as shown in the following figure. Notice that the dialog contains several tabs to modify the elements that control how the BOM is placed and formatted in the drawing. From the General tab, select Standard from the Format selection list, then enable By Pick Placement option and the Lower Right radio button Placement Corner option. Press OK when the dialog appears as shown in the following figure.

Select Standard,then enable the

By Pick andLower Right

options.

4. Press OK to close the configuration dialog. Press OK again to execute the BOM. The AutoPLANT Selections dialog displays. This is the same tool used throughout this tutorial to create a selection set of components.. For example, it would be possible at this point to limit the BOM so that only components from Line L2000 would appear on the report, or to manually select the components that should be included. To generate the BOM on all the components in the drawing, click on the Drawing tab, enable the All radio button, and then press OK.

5. After the model is analyzed and the report prepared, the prompt

Select lower right point:

displays. Type INT and press Enter, then pick the point where the border intersects the top of the title block.

Hint After the BOM is placed, you can move it as an entire block to reposition it more precisely.



Note The BOM can be customized so that it is placed using another method (i.e., by its upper right point), or at a specific coordinate location. Refer to the on-line help file for more information.

6. The BOM is placed in the drawing. Zoom Window around the Bill of Materials to examine it more closely as shown below.

(Imperial Version is Shown)

Note The Annotation > Tags > Material Tag command may be used to annotate the value shown in the No. column above for selected components in the drawing.

GENERATING A BILL OF MATERIALS RETURNING TO MODEL SPACE


RETURNING TO MODEL SPACE

In Chapters 6 and 7, you placed annotation text and graphics in Paper Space. In the procedure below, you will return to Model Space to see how these additions affect your model.

> TO RETURN TO MODEL SPACE

1. Click on the Model tab.

2. AutoCAD returns you to the original view of the model as indicated by the UCS icon in the lower left corner of the drawing area. Notice that the annotation, dimension lines, and Bill of Materials do not appear in the model. These items were placed in Paper Space, and therefore do not appear in Model Space, reducing drawing clutter.

CHAPTER REVIEW

+ Generating a BOM: Select Reports > Bill of Materials to generate the standard BOM. Your model is immediately analyzed, and you are prompted to select a point for insertion. Additional reports include the ability to generate equipment lists, nozzle schedules, and to create custom reports. The Reports > Generate Reports option is also available to generate reports that will not be placed on the drawing sheet.

+ Clean database: The Database Tools > Clean Database option may be executed in order to remove any reference to components which may have been deleted from the model, but have not yet been removed from the drawing database. This option is automatically invoked when you run a BOM.

+ Customization Options: A separate dialog has been provided for customizing the Bill of Materials. This dialog controls placement options, as well as variables such as linetype and scale.

SUMMARY

This completes the drawing phase of the PIPING Tutorial. You should now be familiar with the basic commands and techniques used to complete a model. Combine these techniques in your own models to suit your working style. For specific command reference and more information on customization options, refer to the on-line help provided with each application.

SUPPLEMENTAL APPLICATIONS AUTOPLANT IMPORT/EXPORT


AUTOPLANT IMPORT/EXPORT

The AutoPLANT Import/Export utility is intended to facilitate transfer of CAD data between Bentley’s AutoPLANT PIPING and AutoPIPE stress analysis CAD/CAE software. The transfer is accomplished using our proprietary Plant Exchange Format (PXF), which can either be generated or read by AutoPLANT.

Import/Export also supports output to a Piping Component Format (PCF) for input to Alias Limited’s ISOGEN software for the automatic generation of ISOGEN isometrics. Purchasing a license for AutoPLANT PIPING 2004 Edition SR1 now includes full ISOGEN support.

The application is provided free of charge when you purchase AutoPLANT PIPING and/or EQUIPMENT. The Import/Export application is launched as follows:

1. Start AutoPLANT Plant Design.

2. Select Import/Export from the AutoPLANT 3D menu. The Import/Export menu is added to the AutoCAD menu system.

Hint Refer to the Import/Export on-line help for a detailed explanation of every available feature or function.

SUPPLEMENTAL APPLICATIONS PROJECT TOOLS


PROJECT TOOLS

One of the primary features of Bentley AutoPLANT 2004 Edition is the ability to support SQL databases such as SQL Server and Oracle. Previously, only MS Access was supported and you had to manage your project using manual procedures. There are three modes of operation that you can choose from for a project.

! Standalone mode: single drawing, no project database. Suitable for a one-off drawing or a small project.

! Distributed mode: project database, with individual model MDB files. Most like 2.01 application. Distributed mode is intended for small/medium sized projects where the user wants to continue to run MS Access or MSDE for the primary database while retaining the benefits of a managed project.

! Central mode: all data stored in central project database. Requires MSDE, Oracle, or SQL Server.

Note Central Mode and/or Oracle & SQL Server is an additional cost item

In order to support this new project implementation, several new tools were developed and some prior version tools have been replaced. The following sections introduce many of these tools.

PROJECT ADMINISTRATOR

In AutoPLANT v2.01 the concept of 3D configurations was supported. A configuration was basically a set of files in which drawing and model defaults were stored based on a particular unit (Imperial, Metric, or Mixed Metric). This design enables you to define the units, specs, drawing database format, borders, drawing templates, module and component options, etc. in a specific configuration. The Configuration Editor application was provided to manage these configurations.

The 2004 Edition (and v3.0) provides full project support. In these versions, the configuration data has been moved into the project structure. The Configuration Editor has been replaced by the Project Administrator application, which in addition to providing utilities to create and manage projects, also provides the same functionality that was previously available through the now obsolete Configuration Editor application.

This project implementation provides full integration support between Bentley’s Process and Instrumentation (P&IW) suite of products and Bentley Plant Design (PDW) products.. These applications now share the same central project data repository.



HOW ARE PROJECTS CREATED?

Projects are created using the Project Administrator application. When you create a project you will be asked to specify the desired project mode (as explained above), the Database Type (MS Access, MSDE, Oracle, or SQL Server), the Base Schematic Project Template and the 3D Model Units.

The Base Schematic Project Template contains what was previously used by the P&IW suite of applications as the base project data and project standards used to create a project. The 3D Model Units selection provides Imperial, Metric, and Mixed Metric options and indicates which set of 3D configuration data files will be used to create the project, thereby giving the project a units designation.

The Base Schematic Project Template files used to build the project are copied from your ..\Plant\Base directory when you create a project. The 3D Model Units selected indicates the configuration data files that will be copied from your installation’s ..\Bentley\Plant\Config directory to create the new project.

Note If you are currently using AutoPLANT v2.01 and have created custom configurations, you can use these to create 2004 Edition projects with the Project Administrator. The Project Administrator displays configurations in its navigation tree under the Configurations folder. Project Administrator reads the CONFIGS.INI file in your ..\Config directory to determine the configurations displayed. If you have custom configurations that you want available, you should add group records for these configurations to CONFIGS.INI. You can then create a custom project from any of your custom configurations by simply dragging the custom configuration folder in the navigation tree into a project root directory.

The Project Administrator’s Tools menu provides access to a set of project tools that execute wizards to simply these processes. A brief description of these wizards is provided below.

NAME DESCRIPTION

Project Document Upgrade Wizard

The Project Upgrade Wizard provides a streamlined dialog interface that enables you to take an existing set of AutoPLANT documents created in AutoPLANT v2.01 or earlier and import them into an existing AutoPLANT 2004 Edition project database.

Project Type Conversion Wizard

The Project Type Conversion Wizard will enable convert an existing Central mode project to a Distributed mode project or vice-versa. This wizard will only work on Central and Distributed projects initially created using SQL Server or Oracle database types (i.e., you cannot convert a Distributed project that was initially created using Access or MSDE database types).

Project Export Wizard

The Project Export Wizard enables you to select one or more documents (including all) from a project and create an export package, which may then be imported into another existing project using the Project Import Wizard. This wizard will include all of the information needed for the documents to exist in another project in the export package.



Project Import Wizard

The Project Import Wizard is provided to enable you to import documents contained in an export package created with the Project Export Wizard into another project.

The Project Export Wizard creates an export package zip file that contains the documents that were selected and all of the data associated with those documents. The export package will also contain any other data (configuration data, specs, etc.), that was selected when the package was created.

PROJECT OBJECT MAINTENANCE TOOL

The Project Object Maintenance Tool may only be started via the Bentley > Plant > Project Tools > Project Object Maintenance Tool selection in your Windows Start menu.

When you first start the Project Object Maintenance Tool, you will then be required to select a project that you want to modify. Next, the standard AutoPLANT Login dialog will display prompting you to login to the system.

The project implementation in the 2004 Edition provides the concept of project objects. The value of these objects is used to form relationship between the components in the current drawing as well as across all drawings in that project.

For example, LineNumber is one of the project objects defined in the default project implementation. New LineNumber values may be added to a project using the Project Object Maintenance Tool, or via the Component Preferences control while in a Bentley AutoPLANT application. A component may not be placed unless you have set a value for LineNumber in the Component Preferences control. This will associate the active LineNumber to the component when



it’s placed, thereby forming a relationship between that component and the assigned LineNumber. Any components placed with the same LineNumber value will be related.

This tool was designed to provide a central location for a Project Administrator to manage AutoPLANT project relationship values (e.g., LineNumber, Unit, Area, Service, and Document) on a project-by-project basis. In general, the workflow for AutoPLANT was designed to enable a project administrator to create all of the project relationship object values that will be used on a project at the start of the project outside of AutoCAD. This workflow method provides the Project Administrator with control over the values for these properties on a project-wide basis. It also enables designers to simply select from the provided list of values when creating their models.

The capability to add new project object values is also provided within AutoPLANT applications via the Component Preferences control. This option was provided for those organizations that may want an alternate workflow method. It is expected that in the near future AutoPLANT will provide security settings that will enable a project administrator to control whether or not this functionality is visible to designers within AutoPLANT's Component Preferences control.

This tool is also the only place where a document may be deleted from a project. Deleting a document will delete all of its associated component records and relationships from the project database.

SUPPLEMENTAL APPLICATIONS AUTOPLANT CLASS EDITOR


AUTOPLANT CLASS EDITOR

A module is defined in Bentley AutoPLANT as a set of files that define the components that may be placed when the module is loaded in the PIPING or ISOMETRICS applications. PIPING and ISOMETRICS share module and component class configurations. The following modules are provided with your software.

+ Carbon Steel (default)

+ Cable Tray (PIPING only)

+ Conduit (PIPING only)

+ HVAC (PIPING only)

+ Ductile Iron

+ High Purity

+ Instrumentation

+ Lined Pipe

+ Plastic

+ Tubing

+ Victaulic

The AutoPLANT Class Editor is a tool that enables you to manage these modules on a project-by-project basis. The procedure to start the Class Editor is provided in the next section. The three sections that follow give a brief overview of Class Editor operation and the files involved in this process.

The Class Editor (CE) works hand-in-hand with the Project Administrator application. As noted in the description on project tools earlier in this chapter, a project is created by copying a set of template files based on the units you specify in the project creation wizard. By copying these files into the project, the source template files are preserved and should not be modified. By this same context, a module and its associated component script files should not be modified. The intent of the system design is for you to use the Project Administrator to create your projects, then use the Class Editor to create/modify the module and component scripts and methods for that project. All modified files are stored in your custom project directory structure, therefore, maintaining the integrity of the shipping version files.

When you create a new drawing in PIPING/ISO, and select a project, the system will search your custom project directory path for custom version of all files first. For example, if you used the Project Administrator to create a project named MY_PROJ, then used the CE to modify the drawing script for a gate valve in your MY_PROJ project; CE will save the modified gate valve script within your MY_PROJ project directory structure. When you create a new drawing in PIPING/ISO, and select the MY_PROJ project, then attempt to place this gate valve, the system will search for the gate valve drawing script in your MY_PROJ directory path first, thereby using



your custom script to place the gate valve. If the system does not find a custom file for any component placement, it will use the original source file.

PROGRAM START

The procedure to start AutoPLANT Class Editor (CE) is provided below. This application can be launched from the AutoPLANT 3D menu/toolbar, or from your Windows Start menu.

1. Select Class Editor from the AutoPLANT 3D menu, or select Bentley > Plant > Tools > Class Editor from your Windows Start menu.

The remainder of this section provides an overview of Class Editor operation. Refer to the on-line help for a more detailed explanation of every available feature and function.

GETTING STARTED

When the Class Editor first loads it reads the AT_PROJ.DBF file to get a list of projects in the last active project’s root directory. For example, the figure above shows the Class List dialog that opens when CE reads the project list from the provided sample project root folder.

The project drop-down list enables you to select the project under the indicated project root folder that you want to modify. When you select a project, the navigation tree will automatically be updated to reflect the modules and associated components available in that project. You can also



open an entirely new Class List for a different project root using the File > Open Project Root command.

When a project is selected from the list, CE locates the project’s MODULES.INI, then extracts the module group records into a temporary database, CE.MDB. From the data in this temporary database, CE creates a navigation tree to enable you to view/configure the module and its component methods. The modules defined in MODULES.INI are denoted by the symbol in the navigation tree.

Each module’s main directory is defined in its MODULES.INI record. This tells CE where the component class, methods, ports and specification search criteria control files are located. These files define the components available in the module.

A component is defined by its class record in the file CLASS.INI. In general, a component class defines the Basic Script methods or functions executed to associate intelligence and draw the component. Several components may be assigned to the same class, which defines the base methods that apply to all components assigned to that class. For example, all valves are assigned to the same parent class, which enables you to assign a set of methods that are common to a number of components to a parent class, then assign this parent class to each of these components instead of repeatedly assigning the same methods to all of these similar components.

CE extracts the information in each module’s CLASS.INI, METHODS.INI, PORTS.INI, and SPECKEY.INI files into the temporary database to build the navigation tree for each configuration. Parent class records are depicted in the navigation tree by the symbol, while individual component class records are noted by the symbol.

UPDATING THE CONFIGURATION FILES

As you make changes to the module and component configuration files, CE stores these changes in the temporary CE.MDB database. The File > Save option may be executed at any time during a CE work session to update the project configuration files with changes that have been stored in the CE.MDB database. If you modified one of the provided files (i.e., a gate valve placement script), then CE will save the modified version of this file in your project directory structure, thereby maintaining the integrity of the provided file in its original location.

Since a temporary database stores all of your changes during a CE session, you can play around with the program, then exit without saving to keep your original system intact while experimenting with the Class Editor application.

SUPPLEMENTAL APPLICATIONS SPECIFICATION GENERATOR


SPECIFICATION GENERATOR

The Spec Generator is a stand-alone application whose primary function is to generate specifications for use with Bentley's latest AutoPLANT and AutoPIPE applications. These catalogs and specifications are created in Microsoft Access MDB database format. This file format allows for a catalog/specification’s component tables to be stored in a single file with multiple tables.

When designers build a model, the set of components and size ranges available is determined by the active specification. All catalog and specification information is stored in an MDB (MS Access) database. The Spec Generator is used to build this database and assign unique IDs to each component in the specification, which is required by the latest AutoPLANT applications.

In addition to its primary function of generating specs, the Spec Generator is also a Catalog Editor. Use it to add to the set of records contained in an existing catalog, or edit existing catalog records. You can also define the types of input allowed in certain fields, add new tables to an existing database, delete fields from existing tables, and a variety of other customization features.

The Spec Generator may be launched from your Windows Start menu by selecting Bentley > Plant > SpecGen > Specification Generator.

Note Refer to the Spec Generator on-line help for a complete description of every available feature and function. This help also describes the process of updating your previous AutoPLANT version specs to work with v3.0

SUPPLEMENTAL APPLICATIONS SPECIFICATION GENERATOR


WHAT IS A CATALOG?

A catalog is a Microsoft Access database that contains a rich selection of component records from which manufacturer specific specifications can be created. Bentley provides several sample working catalogs of tens of thousands of components from which manufacturer-specific specifications may be produced.

WHAT IS A SPECIFICATION?

A specification is a Microsoft Access database that is basically a subset of a catalog. Specifications can be edited or modified to suit unique requirements, and any number of specifications can be created. In addition to the sample catalogs, Bentley provides several sample specifications for Imperial, Metric, and Mixed Metric units. The Spec Generator program enables you to build and customize the database specifications used with particular projects or clients.

HOW DOES IT WORK?

If you have used previous versions of the Spec Generator, you will appreciate the simplicity of the new program architecture. This architecture is based on a working method generally more familiar to piping designers, the spec sheet. A spec sheet is generally broken into component sections as illustrated in the figure from a spec sheet below.

The Spec Generator uses this working method to generate specifications from the selected catalogs. You basically add a section for each component type you want included in your spec, define the constraint, or query used to extract the selection set of records from the catalog(s) for each section, and then build the spec based on these constraints. This architecture also simplifies the update process, by enabling you to review/modify each component section individually. If you need to make a change, simply modify the constraint for the desired section, then rebuild the spec.

SUPPLEMENTAL APPLICATIONS 2D TO 3D CONSISTENCY CHECKER


2D TO 3D CONSISTENCY CHECKER

The AutoPLANT 2D to 3D Consistency Checker is a tool that enables items in AutoPLANT P&ID to be compared with equivalent components in AutoPLANT PIPING and EQUIPMENT.

Note You must have AutoDesk’s Volo™ View Express installed in order for this function to work.

There are two main user interfaces that may be used to perform consistency checks:

2D TO 3D CONSISTENCY REPORTER

The 2D to 3D Consistency Reporter is an application that enables you to select a project, perform consistency checks, graphically review the consistency check results, and generate printed reports of the results.

The application is launched by selecting Bentley > Plant > Project Tools > 2D to 3D Consistency Reporter from your Windows Start menu.

SUPPLEMENTAL APPLICATIONS 2D TO 3D CONSISTENCY CHECKER


AUTOPLANT 2D BROWSER ACTIVEX CONTROL

The AutoPLANT 2D Browser ActiveX control is a control that may be docked in an AutoCAD/AutoPLANT session or in any other application that supports embeddable ActiveX controls. This control enables you to perform consistency checks, and graphically see the consistency check results.

The control is launched by selecting 2D to 3D from the Piping or Equipment menus.

The non-user interface parts of the system for which you may be interested are the 2D-to-3D mapping tables that reside in the project database. These tables enable you to customize the mapping of 2D items to 3D according to his/her specific needs.

SUPPLEMENTAL APPLICATIONS SCRIPT EDITOR


SCRIPT EDITOR

AutoPLANT provides an intuitive and highly functional script editor to create/customize BasicScript function and component drawing scripts. The Script Editor highlights keywords, commands, etc. to simplify the script construction process. You may elect to use this editor, or one that you are already more familiar with to create your basic scripts.

PROGRAM START

The procedure to start Script Editor is provided below. This application can be launched from the AutoPLANT 3D menu/toolbar or from the Windows Start menu.

1. From your Windows Start menu, select Bentley > Plant > Tools > Script Editor to start the Script Editor application. This editor highlights standard Basic language data types, controls, functions, and comments to simplify the editing process.

2. Context-sensitive help is provided for most standard Basic language elements by simply placing the cursor within the element you need help on and then pressing the F1 function key. For example, select File > Open then open the VALVES.EBS file from your ...\MODULES\BASE\PIPING\DRAW directory. Scroll down the file and move the cursor into one of the standard Basic elements, which will be highlighted in blue as shown below, then press F1 to display its help.

SUPPLEMENTAL APPLICATIONS SCRIPT EDITOR


3. This functionality is also available for the AutoPLANT API Extensions to the Basic language. Most of these extensions are easy to identify within a script because they start with the string “at_”. For example, select Edit > Find and type at_Component_getPoint and then press Find Next. Move your cursor anywhere within this function call, then press F1 to display its help as shown below.

DEBUG MODE

The Script Editor can also be placed in debug mode by enabling the Debug Mode check box in PIPING’s Drawing Preferences dialog. If this switch is enabled when you execute a PIPING component placement command, the drawing scripts that are executed will display in the Script Editor to enable you to step through each statements that is executed to draw the component.

This switch should only be enabled when you are modifying or customizing PIPING component placement or function Basic script files.

SUPPLEMENTAL APPLICATIONS DIALOG EDITOR


DIALOG EDITOR

The Dialog Editor provides an intuitive graphical user interface to create/customize AutoPLANT compatible Basic dialogs that may be used in your Basic scripts and functions. These dialogs can be inserted directly into custom scripts created with the Script Editor.

PROGRAM START

The procedure to start Dialog Editor is provided below. This application can be launched from the AutoPLANT 3D menu/toolbar or from the Windows Start menu.

1. From your Windows Start menu, select Bentley > Plant > Tools > Dialog Editor from the AutoPLANT 3D menu or toolbar to start the Dialog Editor application shown below.

This application can also be launched directly from within the Script Editor by selecting the Edit > Insert New Dialog command. This command will start the Dialog Editor, enable you to define a new dialog instance, then exit the Dialog Editor and automatically insert the Basic statements that define the dialog instance into your script in the Script Editor.

You can also modify a dialog that is already defined in a script by simply selecting the statements that define the dialog in the editor, then selecting the Edit > Edit Dialog command. This will display the dialog instance in the Dialog Editor. When you have finished modifying the dialog, select File > Update to update the dialog statements in the script. Then select File > Exit and Return to close the Dialog Editor.

SUPPLEMENTAL APPLICATIONS AUTOPLANT DRAWING FLATTENER


AUTOPLANT DRAWING FLATTENER

The AutoPLANT Drawing Flattener is a standalone application, which must be purchased and authorized separately. AutoPLANT PIPING/RACEWAYS provide a set of commands in their Drafting Tools > Hide Viewport submenu that contain a minimal subset of this functionality on an individual drawing/viewport basis.

The Drawing Flattener enables you to create flat DWG file that corresponds with a user-selected model layout stored in the source drawing (DWG file) with a user-defined scale. The drawing layout is a rendering of the flat drawing in the view only and cannot be edited. The Drawing Flattener creates AutoCAD 2D entities for the flattened drawing enabling you to edit the result. Therefore, you will see the creation of lines, arcs, circles, etc. in the flattened output.

This application will operate with AutoCAD drawings (DWG files) only. The source for the application is DWG file(s) with layers, while the destination is DWG file(s) created according to the selected layer and scale of the drawings.

To start the flattener, select Bentley > Plant > Tools > Drawing Flattener from your Windows Start menu.

The Flattener main dialog provides a streamlined interface. The main dialog consists of a grid with columns that describe how each source drawing will be flattened, and a set of menu commands that enable you to configure these settings and additional flattening preferences. The display of the Log and Status areas at the bottom of the dialog may be toggled ON/OFF via the View menu.

The grid is where you setup the drawings to be processed by the flattener. Drawings are add/removed from the grid using the File > Add Files to List and Remove Files from List options. The drawing name will appear in the Source column.

SUPPLEMENTAL APPLICATIONS AUTOPLANT DRAWING FLATTENER


The Dest. Folder column indicates the location where the flattened drawings will be stored. This may be changed for drawings individually by double-clicking within the field, or may be changed for a group of drawings by highlighting the drawings in the grid, then executing the Group Edit Selected command from the Edit menu.

The Dest. Filename column indicates the name for the flattened output drawing file. You can modify this file name for each file individually by double-clicking within the field, or you can assign a prefix and/or suffix that will automatically be added to the actual file name via the Edit > Preferences dialog.

The Layout column provides a list of AutoCAD layouts that were created in each source file. Click within this field, then select the layout that you want to use to create your flattened drawing. If you add additional layouts to a file, you can use the Refresh Layouts for Selected command in the File menu to update the drop-down list of layouts shown for the selected files.

The Scale column indicates the scale that will be applied in the creation of the flattened output file. You can double-click within this field and manually enter a scale value, or leave the default Auto scale, which will use the source layout's last view port scale. The default value may be assigned for this field via the Edit > Preferences dialog.

The remaining commands in the menu are primarily provided to enable you to manipulate the column data in the grid. The only exception is the Edit > Preferences command, which enables you to set up defaults, and more importantly assign the hidden line removal parameters used by the application.

SUPPLEMENTAL APPLICATIONS EXPLORER/ID


EXPLORER/ID

EXPLORER, which may be purchased separately, is an interactive 3D viewer for large models and sets of models as shown below. You can load multiple models varying from thousands to millions of triangles in size and interact with them at a guaranteed frame rate.

EXPLORER supports multiple file formats via a plugin mechanism. As well as its own native file formats, AutoCAD’s DWG and DXF files and 3D Studio’s 3DS files are supported.

A range of navigating and viewing controls enable even the largest and most complex model to be explored with ease.

EXPLORER PROGRAM START

The procedure to start Explorer is provided below. This application can be launched from the AutoPLANT 3D menu/toolbar or from the Windows Start menu.

INTERFERENCE DETECTION MODULE

The EXPLORER ID interference detection add-on module may be purchased separately. It provides a re-sizable modeless tabbed dialog as shown below.

EXPLORER/ID PROGRAM START

The procedure to start Explorer ID is provided below. This application can be launched from the AutoPLANT 3D menu/toolbar or from the Windows Start menu.

1. Select Explorer ID from the AutoPLANT 3D menu, or select Bentley > Plant > Explorer ID > Explorer ID from your Windows Start menu.

2. All of the options provided with standard Explorer are available in Explorer ID. The only difference is that a Check Interferences option has been added to the Tools menu to enable you to perform interference detection in the ID module.

3. Open an AutoPLANT drawing then select Tools > Check Interferences to display the following dialog.



Explorer ID checks your model and shows you any areas where the models interfere or ‘clash ’ with each other. Explorer ID is a tabbed dialog box accessed through the Tools menu, allowing you to manage your test and results. From the Explorer ID dialog box you can set up your clash tests, view the results, sort the results and produce a report.

Managing a series of clash tests can get complicated, especially if you have a whole set of different layers you want to clash separately. The Explorer ID is designed to help you control these clash tests and leave an audit trail of clashes throughout the life of the project.

One simple but time-saving way it does this is by remembering the names of clashes throughout the project’s life so you don’t have to go through each clash every time you do a test to figure out whether it’s a new clash, or one you’ve already seen and approved.

The Explorer ID also allows you to assign a status to a clash and can update this status automatically, informing you of the current state of the clashes in the model.

You can set up a batch of clash tests that you could run overnight, every night and for each test, choose the objects to clash against, along with the options for the test. These batches can be saved as *.nwx files, independently of Explorer files.
