Preface The information contained in this document is intended for any and all CAD work completed for The Port of Tacoma, internally or by outside contract. The basis of developing the CAD Standards & Procedures is to maintain consistency throughout the drawings for the Port of Tacoma. This helps the CAD Department immensely in managing the plans and providing well managed plans to port personnel and consultants for future needs. All consultants that provide plans to The Port of Tacoma need to adhere to these standards. Drawings that do not comply with these CAD Standards & Procedures may not be accepted. The CAD Department is responsible for creating, managing, implementing, and providing the CAD Standards & Procedures for all of the Port of Tacoma’s consultants that provide plans to the Port of Tacoma. The Port of Tacoma currently uses AutoCAD Map 3D Release 2008, but we require all of our drawing to be saved in AutoCAD Version 2004 “dwg” format to correspond with those that have older versions of AutoCAD. This is a dynamic document that will change as the CAD Department evolves in response to customer needs, available resources, and technological growth. Consultants are responsible to stay informed and ask for the latest revisions of the CAD Standards & Procedures when they work on new projects for the Port of Tacoma. Every effort has gone into these CAD Standards and Procedures to ensure that they are basic and easy to follow without creating a large amount of extra work for CAD Technicians, Engineers, and Architects to comply. The Port of Tacoma CAD Department is committed to providing their customers & clients with the highest standards and best practices. Your suggestions are an important part of that commitment.

Chapter 1 – Plan Files 1.1 Requesting & Submitting Plan Files

The Port of Tacoma currently uses AutoCAD Map 3D Release 2008, but we require all of our drawings to be saved in AutoCAD Version 2004 “dwg” format to correspond with those that have older versions of AutoCAD. Drawings submitted to The Port of Tacoma by outside contractor must be saved in this format. Consultants may request copies of existing CAD data from the Port of Tacoma. CAD data is provided for the convenience of the recipient only. This data has been gathered from a variety of sources, and it may or may not conform to current CAD standards set forth by the Port of Tacoma. Also, the data may be incomplete or may not accurately reflect current conditions. The Port of Tacoma makes no representation as to the completeness or accuracy of the data. Consultants should keep in mind that CAD data may appear to be accurate because it is computer-generated, however, its appearance does not guarantee that the data truly represent existing conditions. 1.2 Accepted Drawings & File Formats

CAD drawings that consultants submit to the Port of Tacoma must be accurate and conform to the current CAD standards, even if data that the Port of Tacoma provided to the consultant was inaccurate or did not conform to the standards. Record Drawings for projects must be provided to the Port of Tacoma in ALL of the following formats:

1. DWG – These drawings can be used in CAD and we can make modifications to them in the future if we need to. (Version - AutoCAD 2004)

2. PDF – This is a standard format that everyone can see using Acrobat Reader.

These drawings need to be formatted to print to a ½ scale set on 11X17.

3. TIFF – These drawings can be loaded into and seen by using our internal Drawing Viewer. Size: Ansi-D (22x34), Black & White.

4. 1 Full-Scaled hard copy set (ANSI-D, 22x34) & 1 Half-Scaled hard copy set

(11x17). Note: This can be in place of the TIFF Files. It is recommended that all other planning phases are sent this way as well after the Bid Set is approved. This is at the Project Manager’s discretion. The Port of Tacoma shall validate all CAD data and other materials that the consultant submits. If submittals do not conform to the CAD Data standards, the Port of Tacoma can reject the submittals from the consultant. The consultant is responsible for making revisions to the materials to make them conform to the Port of Tacoma Standards.

Port of Tacoma CAD Standards 11/1/2007 1

1.3 Media Types

For hard copy sets of plans that are submitted to the Port of Tacoma, bond paper is the requirement. Bond paper is easier to scan and take out into the field if needed. 1.4 Plan Archiving

The Port of Tacoma will keep copies of the Bid Sets and Record Sets for all Projects in the formats that are listed above in section 1.2. 1.5 File Naming Convention

All project drawings that are issued to the Port of Tacoma should be provided to in the following manner. The following are examples of how project drawing files should be named.

1.5a Project files representing one sheet of a drawing set

• Single Drawing DWG Examples: E2086-E1.dwg • Single Drawing PDF File Examples: E2086-E1.pdf • Single Drawing TIFF File Examples: 6301-00_000E1.tif 1.5b Project files with multiple sheets in a project drawing set

• Project Drawing File Examples: E2086.dwg • Project Drawing PDF File Examples: E2086.pdf • “Tiffs are to be in single sheet format only”

1.6 File Drawing Naming Structure

• DWG & PDF Files

Example - Single Sheet Drawing: E2086-E1.dwg, E2086-E1.pdf

E2086 = Represents the Project Number E1 = Represents the Sheet Number (Sheet #1 of the

Electrical set)

Example - Multiple Sheet Drawing: E2086.dwg, E2086.pdf

• TIFF Files

Example: 6301-22_000E1.tif

6301 = Represents the Drawing Number 00 = Represents Drawer Number (This is going away, so we

can use 00 for now) 000E1 = Represents the Sheet Number


1.7 File Folder Structure

Here is the structure of the Project Drawings Folders as it is stored on the server. Drive:\

\Main CAD Folder \Main Project Folder

\Project Name Folder \Drawing Phase (I.E Bid, Construction, Record, Permit, etc)

\Drawing Format \Files

Example: L:\PTac Cad\PTac Proj\E2086\Record\PDF\E2086-E1.pdf For large projects, subdirectories may be created to separate out the drawing disciplines, such as Civil, Electrical, Survey, etc. 1.8 File Size

Every effort must be made to reduce file size of drawings. It is the responsibility of the consultant to organize project drawing information coherently and-maintain reasonable file sizes. Major contributors to excessive file sizes are unreferenced blocks, Overlapping lines, and redundant line work and hatches. Files should be PURGED before submittal to remove unnecessary data and reduce file size. Unreferenced or Nested Block = A block that is hidden or unused within a drawing. Redundant Lines = Lines that have no meaning or that are on top of other lines. 1.9 Project Plan Phases

30% “An estimated 30% of drawing completion.” Plans retained at Project Manger’s discretion.

60% “An estimated 60% of drawing completion. “ Plans retained at Project Manger’s discretion.

90% “An estimated 90% of drawing completion.” Plans retained at Project Manger’s discretion.

Bid Set Must be provided to the Port of Tacoma’s Cad Department in the accepted Formats. “The Set of Drawings that go to Bid signed off by the Chief Engineer and Consultant”

Construction Set Plans retained at Project Manger’s discretion. “Plans that are Issued for construction.”

Conformed Set Plans retained at Project Manger’s discretion. As-Built Set These plans are the final markups. They should be updated by the

consultant to establish “the Record Set”. Record Set Must be provided to the Port of Tacoma’s Cad Department in the

accepted Formats listed in Section 1.2. “The Record Set of drawings contains all signatures, redlines, clouds, and edits updated within the plans so that they are now part of the document.”


Chapter 2 – Sheets 2.1 Sheet Size Formats

There are only two sheet size formats that shall be used and accepted by the Port of Tacoma, for hard copy drawings that are provided by an outside contractor, consultant or A/E firm. These plans should be provided on bond or coated paper only.

• Full scale size = 22x34 (ANSI D) • ½ scale size = 11x17

2.2 Sheet Designation

The following list consists of the drawing disciplines for the project sheets at the Port of Tacoma. Sheet Designation Discipline Description A Architectural B Geo Technical C Civil D Demolition E Electrical F Fire Protection G General Notes H Hazardous Materials I Interiors L Landscaping M Mechanical O Operations P Plumbing Q Equipment S Structural T Telecommunications U Utilities V Survey/Mapping W Civil Works Z Contractor/Shop Example: This example indicates that this is Sheet 1 of the General Notes.


2.3 Sheet Legend

A sheet legend must be provided in order for the Port of Tacoma to accept the drawings. A sheet legend for the project drawing set must be listed on the Cover Page or the 1st page of the General Notes. 2.4 Sheet Designation Limitations

• The sheet designation should be limited to only 5 characters. There is no need to have more than 5 characters within a sheet designation.

• Besides the first letter in the sheet designation, the rest of the sheet designation should be limited to only numbers. No use of letters, symbols, or other characters in the rest of the sheet designation.

2.5 Sheet Set Manager

Using the Sheet Set Manager and Publish Commands in Single Document Interface Mode (SDI) The Sheet Set Manager in Autodesk® Land Desktop is a major leap forward in terms of creating, organizing, and annotating entire sheet sets. To accomplish this, the Sheet Set Manager takes advantage of the enhanced Publish command, the new mtext fields, and an enhanced sheet set organization tool. Because other Autodesk® products also include these new features, they were designed with a multiple document interface (MDI) in mind. Autodesk Land Desktop 2005, like earlier releases of the product, supports only single document interface (SDI) mode, and therefore some features are not available. To make full use of these new AutoCAD® 2005–based features, Autodesk encourages Land Desktop 2005 users to implement Land-enabled Autodesk Map® 2005 software, which is automatically installed with Land Desktop and runs in MDI mode. This document describes the MDI-based features that are not available or have only limited functionality in Land Desktop. Autodesk Civil Design 2005 Sheet Manager and Autodesk Land Desktop 2005 Sheet Set Manager are separate features. Although similarly named, the Sheet Manager in Autodesk® Civil Design is completely separate from the new Sheet Set Manager in Autodesk Land Desktop. The two features are not integrated, but sheets (layouts) from the Civil Design Sheet Manager can be used and managed in the new Sheet Set Manager. In SDI mode, the Sheet Set Manager Open command is visible but, when selected, does not open the drawing. Drawings should still be opened using the normal Open command from the command line or from the file pull-down menu. Note that the Sheet Set Manager open functionality is available in Land-enabled Autodesk Map 2005. Publish to Web command is limited. In Land Desktop 2005, the Publish to Web command is limited to publishing content from the currently open drawing only. If you attempt to add any other drawings in the “publish to web” command, they will not be included in the final output. 2.6 Sheet Set Protocol

Sheet sets are recommended to be developed for project drawing packages that are given to the Port of Tacoma. If a Sheet Set File is generated for a set of project drawings, the Sheet Set File must be placed in the same directory as the main DWG Files. A sheet set should be developed, so that each drawing sheet is setup ready to plot in the paper space environment at half scale.


Chapter 3 – Titleblocks

3.1 Titleblocks

All Drawing Files submitted to the Port of Tacoma should have the standard Port of Tacoma titleblock. This titleblock will, and should always reside within the Paper Space of each drawing. Each titleblock has attributes tags that are what makes up the records of each drawing. These attribute tags on each titleblock need to be filled out completely in order for the drawings to be accepted by the Port of Tacoma. Consultants are responsible to stay informed and ask for the most current Port of Tacoma Titleblock & Coversheet. 3.2 Parts of a Title Block

• Drawing Number (EP#) = A drawing number is needed for each project. (Contact Cadd Specialist to get number – Brian Archer 253-383-5841 #221)

• Sheet Designation = Sheet Designation Letter (See section 2.2) and the number of that sheet set.

• Sheet Number = Number within a drawing set. Example: (1 of 20) • Project Number (E####) = the Project Number • Phase = Drawing Phase: 30% Set, 60% Set, 90% Set, Bid Set, Construction Set,

Record Set, Survey Set, As-Built Set, Etc. • Geographic Location = Terminal, Rail, or Intersection Name, Location of Project • Project Description = Main Project Title • Title = Discipline Description IE: (General Notes, Structural, Electrical, Utilities,

Mechanical, Survey, Civil, Etc.) • Address = The address of the location of the project • Datum = Horizontal & Vertical Datum defined by the Port of Tacoma • Parcel # = The Port Parcel Number • Drawing Scale = A scale should be designated by sheet or put “N/A” if bar scales or

various scales are used on a sheet. • Township/Range/Section = The Township, Range, Section put forth by the Public Land

Survey System (PLSS) and the U.S. Geological Survey (USGS) • Approved = The Port of Tacoma Chief Engineer’s Signature for approval. • Checked By = The Consultants Plan Checker’s Initials and Date of Initials. • Project Engineer/Date = The Consultants Project Engineer’s Initials and Date of Initials. • Chief Engineer/Date = The Port of Tacoma Chief Engineer’s Date of Signature. • Printed By = This is automatically generated and is setup this way within the titleblock.

Each time the sheet is printed it will capture the user’s name. • Port Address = It’s automatically generated and is setup this way within the titleblock. • Revisions = Any revisions done or asked to do by the consultant. (All revisions shall be

clouded and depicted by a triangle with the revision number inside it.) • Port Logo & Address = The Port Logo and Address is automatically placed within the

titleblock. • Engineers’ Stamp = Washington State Board Registered Professional Engineer or

Chapter 4 – Drawing Environment 4.1 The Two Drawing Environments

There are two distinct working environments, or “spaces,” in which you can create objects in an AutoCAD drawing. These are represented by the Model (Model Space) and Layout Tabs, (Paper Space). A drawing can have several Layout Tabs or just one layout within it. These Layout Tabs are within the Paper Space views of a drawing. There are several benefits to switching between Model space and Paper space to perform certain tasks. Use Model space for creating and editing your drawing model. Use Paper space for composing your drawing sheet, defining views, and plotting.

4.1a Model Space

Model space is AutoCAD’s working mode for developing the drawing. The drawing is always drawn in model space and at full scale (1:1). Any additional items that help define the drawing data such as details, schedules or sections must also be drawn at full scale in model space. This information then can be scaled to fit within a sheet in the paper space view.

4.1b Paper Space

Paper space enables you to take the drawing that was drawn in model space and create a variety of views for plotting at different scales. Each paper space layout represents a sheet to be plotted at a designated scale. Viewport/s are created in paper space and scaled to fit at certain scales on the sheet. General project graphic elements such as titleblocks, legends, key plans, plan titles, vicinity maps, and sheet specific notes should be drawn or inserted as blocks within paper space.

4.2 Layouts

A drawing can have Multiple Layout Tabs or just one layout within it (Unless you are using Land Desktop). These Layout Tabs are within the Paper Space views of a drawing. Multiple Layout tabs within a drawing. 4.3 Layout Viewports

You can create a single layout viewport that fits the entire layout or create multiple layout viewports in the layout. When you create a layout, you can add layout viewports that act as windows into model space. In each layout viewport, you can control the view that is displayed. Once you create the viewports, you can change their scale size by using the “viewport scale control” within paper space. This “viewport scale control” will determine your plot scale. Plot Scales will already be set-up within the Port standard drawing.

• Viewports shall be created on layer “Defpoints” or some other, preapproved, non-plotting layer.

4.4 Drawing Rotation for Plotting

If you rotate a drawing in model space for design purposes, you must rotate it back before submitting it to the Port of Tacoma. Drawing rotation for plotting purposes must be setup by using the “mvsetup” command. This must be done within a viewport in paper space.


4.5 Drawing Units

The Port of Tacoma’s standards for drawings should be setup in Decimal Units. The Insertion Scale should be set in feet. AutoCAD Drawings should be setup in the following manner:

MLLW TO NAVD 88 SUBTRACT 2.67' MLLW ELEV.-2.67'=NAVD 88 ELEV.


Chapter 5 - Layers 5.1 Industry CAD Standards for Layering

The Port of Tacoma follows two major Industry CAD standards for layer naming conventions. Why the 2 standards? These Layering Standards are the most commonly used standards in the CAD Community. Every effort has been made by the Port of Tacoma to evaluate current and past plans received by consultants to discover the most commonly used layering methods and apply those to our standards while complying with industry standards as best as possible. 5.2 NCS/AIA Layering Standard

This standard is setup primarily for Building Architecture. The NCS (National CAD Standard), AIA (American Institute of Architects) standards are to be used for Architectural, Interior, and Facility Management Drawings.

5.2a NCS/AIA Building Features

The U.S.-based National CAD Standard (NCS) is a system for organizing and classifying drawing-centric building design data. Drawings that will follow the NCS/AIA CAD Standards are to include all of the following building features:

A. Building Architecture

• Interior and Exterior Walls • Interior and Exterior Windows • Interior and Exterior Doors • Ceiling / Floor Grids

B. Building Structural Plans and Details C. Building Electrical Drawings D. Building Mechanical Drawings E. Building Plumbing Drawings F. Casework or Millwork Drawings G. Details and Room Numbers H. Furniture & Equipment Drawings I. Building Plumbing Drawings J. Building Sections, Details, & Schedules K. Parking Lot & Site Plans and/or Details (Only 5ft out from building)

5.2b NCS/AIA Layering Organization

The NCS layering system is based on the AIA CAD layer guidelines, with the layer names organized as a hierarchy. You can select from a number of options for naming layers according the level of detail required. There are four defined layer name data fields: Discipline Designator, Major Group, two fields for Minor Group, and Status. The Discipline Designator and Major Group fields are mandatory. The Minor Group and Status fields are optional.

Discipline Designator: Disciple Designator denotes the category of subject matter contained on the specified layer. It consists of a two-character field, with the first character the mandatory discipline character, and the second, an optional modifier.


Example: A Architectural

Major Group: Major Group is a four-character field that identifies a major building system.

Example: A-WALL Architectural, Wall

Minor Group: This is an optional, four-character field used to further define the Major Groups.

Example: A-WALL-FULL Architectural, Wall, Full height

A second Minor Group field can be used to further delineate the data. Example: A-WALL-FULL-TEXT Architectural, Wall, Full height, Text

Status (Phase): Status is an optional single-character field that distinguishes the data contained in the layer according to the status of the work or construction phase.

Example: A-WALL-FULL-N Architectural, Wall, Full height, New work

5.2c NCS/AIA Discipline Designations

The following is the computer-aided drafting layer naming convention used for Architecture, Interiors, & Facility Management at the Port of Tacoma. These standards are taken from the AIA and NCS Standards. Discipline Designator Discipline Description A Architectural C Civil Engineering & Site Work E Electrical F Fire Protection L Landscaping M Mechanical P Plumbing S Structural

*GEN General Reference Items

It is very important that the Discipline Designator the Port of Tacoma has established is followed when naming layers. Layers are organized alphabetically and this provides an adequate way of grouping layers. For more information regarding Major, and Minor Groups for this layer naming method, please see the CAD Layer Guidelines Manual. An AIA manual can be obtained from the address written below. For more information about NCS, visit www.nationalcadstandard.org. The American Institute of Architects 1735 New York Ave., NW Washington, DC 20006-5292


5.3 APWA Layering Standard

This standard is to be used for all applications outside of Building Architecture as described in section 5.2. The APWA (American Public Works Association) Standards are to be used for Engineering, Civil, Survey & all other Drawing Disciplines other than Architectural. The APWA layer standard is based on four-part layer names to allow the user to control layer display and status through the use of wild card characters. Each part name describes a particular characteristic of the entities contained in that layer. The first part of the name is the Discipline Designator that the objects are associated with. The second part name describes the type of object to be drawn. The third part describes the state of the object and the fourth part of the name represents the AutoCAD entity that is being used.

It is very important that the Discipline Designator the Port of Tacoma has established is followed when naming layers. Layers are organized alphabetically and this provides an adequate way of grouping layers.

5.3a APWA Discipline Designations

The following is the computer-aided drafting layer naming convention used for Engineering, Civil, Survey, Public Works, & All Other Drawings not associated to Building Architecture at the Port of Tacoma. These standards are taken from the APWA Standards, and review of past drawings issued to the Port of Tacoma.

Chapter 6 – Blocks 6.1 Blocks Creation

Here are some industry standards that are adopted by the Port of Tacoma for block creation. These standards need to be followed by contractors & A/E consultants submitting drawings to the Port of Tacoma. For Utility Blocks within drawings use the APWA Standards for blocks; however, Most of the blocks in the current APWA Standards were not created on the “0” layer and were not drawn to scale, so these blocks were redrawn by the Port of Tacoma and a block library has been established by the Port of Tacoma. The names of all the blocks have been developed to match the (APWASYM2 and APWAWAT2) standards. The following are the standard rules for creating, storing, and using blocks: 1. All blocks will be created on the layer “0” and defined on layer “0”. NO EXCEPTIONS!

2. All blocks color should be set to “bylayer”.

3. All blocks lineweight should be at “0.00”.

4. All blocks will be created with a “reasonable” Architectural snap set, depending on the drawing discipline. Smaller snap sets will be allowed for 1-line and system flow diagram drawings. (Architectural - “1/8” typical & Engineering - .25 typical)

5. All blocks will be defined with insertion points at the object snaps of the object. Typical Snap locations for blocks are the center of the object or the lower left corner.

6. All attribute text styles will follow the text style standards of this manual.

7. All new blocks will be saved by creating “wblocks” of the new blocks and will be stored in the appropriate block (symbol) library. All blocks will be stored in a library located in an appropriate folder on the server under the symbol group for which it belongs.

8. All blocks will be organized and placed in one drawing file so that they are easy to maintain.

9. Blocks will be named using a method similar to our file naming convention, or an Industry standard. Utility blocks will use the APWA Standard unless the standard has not developed the block.

10. Dynamic Blocks are not used at this time due to the variances that you can have within a dynamic block.

6.2 Port of Tacoma Blocks

The Port of Tacoma has developed blocks within a ‘Master Drawing.dwg’, as well as maintained the blocks within individual drawing files to create a block library. It is recommended that consultants use these blocks for consistency within drawings for the Port of Tacoma. If you need access to these files please contact the Port of Tacoma’s CADD Specialist (Brian Archer @ 253-383-5841 #221). For any additional blocks that you may need or use within your drawings, please forward individual drawing files of your blocks and a list describing each block to the Port of Tacoma. After review, the Port of Tacoma may adopt these new blocks within their CADD Standards.


Chapter 7 – Linetype Standards 7.1 Linetype Standards

Linetypes are used in drawings to delineate lines for clear identification. They can be used on any layer. Complex linetypes for mechanical drafting can have letters imbedded in the line to show the function of the line or pipe it represents. The “ltscale” or “linetype scale” will be determined by the individual for best representation of the linetype text. “ltscale” of “0.25” or “0.5” will be used rather than “0.23” or “0.497” respectively. The existing Linetype definitions that are packaged with AutoCAD are sufficient for most of the Port of Tacoma CAD Department and its customer’s needs. These Linetypes are the industry standard and are recognized as the standard in this document. The standard AutoCAD linetypes are stored in the “acad.lin” file. Some additional linetypes along with the APWA linetype standards have been added to the “acad.lin” file and renamed as “(Most recent date) - ptac.lin”. This will be the standard linetypes used at the Port of Tacoma. Examples of special linetypes showing the purpose of the mechanical lines are shown on the next page. They are stored in the “071025 - PTac.lin” file.


7.2 Major Linetypes


Chapter 8 - Text Styles 8.1 Text Styles

The Port of Tacoma Standards for naming text styles is to match the font style that is being used in Uppercase. For Example: If you want to use the font “romans.shx”, you will name your text style “ROMANS”. All of your settings will be set to the default. See the diagram below. The only exceptions to this rule are: Standard = The Port of Tacoma uses the “simplex.shx” font typically for this style. TITLE = This style now uses the “Arial“ font set to “Bold” instead of the “hmf1.shx” font,

and is mainly used within the Port of Tacoma TitleBlock. The existing Text Style definitions that are packaged with AutoCAD are sufficient for most of the Port of Tacoma CAD Department and its customer’s needs. These Text Styles are the industry standard and are recognized as the standard in this document. They should be left at a Height of “0” so that AutoCAD can prompt for a height when the text is entered into the drawing. By leaving the standard text style height at “0” you can change the text style height to what you need when prompted, therefore not having to create multiple text styles using the same font.

Chapter 9 - Dimension Style Standards 9.1 Dimension Styles

“Dimension Styles” are a named group of dimension settings that determine the appearance of the dimension. Each style depends on the drawing type, drawing scale, and application. The contractor and A/E consultants will need to follow the Port of Tacoma set of standards. This will represent the dimensioned object or objects in the clearest form possible for the Port of Tacoma while staying within the industry standard for dimensioning. The text that goes along with the dimensioning should always be linked with the dimensioning and never exploded. This assures users the ability to modify dimensions knowing that the text will be updated as well. Dimension style colors will always be set to “bylayer”. All dimension variables will reside on the same layer. If a dimension resides on a layer named “GEN-DIMS”, then the dimension line color, extension line color, and dimension text color will also reside on layer “GEN-DIMS”. All Dimension Styles will have the Text Color set to “White” for best clarity when printing. This is already setup within the Port of Tacoma standard Dimension Styles. The only modifications a contractor or A/E consultant may do to a standard Port of Tacoma dimension style may be with the leader line in that they may adjust a dimensions leader to Loop or have an arrow, etc. depending on the drawing needs. Also the contractor or A/E consultant may adjust the dimension text location if it does not fit within the dimension callout. The dimension styles will all be located within a default drawing setup file or titleblock that includes all of the other Port of Tacoma CAD Departments standards such as (Layouts, Linetypes, Variables, Text Styles, Etc). The drawings system variable “dimscale” should always be set to “1” since the dimension styles are already set up. If a drawing requires multiple views using multi-size dimensions, then a different dimension styles will be used accordingly for each view. Below is an image depicting a list of the Port of Tacoma Dimensions that are within the Port Titleblock Drawings.


Chapter 10 - External References 10.1 General XREF Information

The following are required when using external references:

1. Xref drawings should follow the Port of Tacoma’s coordinate system so that when inserted, an xref drawing will align with the base drawing. Insert external references (xrefs) at (0, 0, 0) no exceptions.

2. Xrefs will only be used when necessary.

3. Xref drawings will be in an appropriate folder structure set by the Port of Tacoma, with a maximum of 1 subdirectory.

4. Only full path attachments of xrefs may be made. No overlays. 10.2 XREF Folder & File Structure

1. Naming convention for Proposed XREF Items [Proj. No.]-X-[APWA Discipline Designator][Sequence 01 -> 99 (if needed - 4 character limit)] Example, assuming the Project Number to be E4301: E4301-X-SD.dwg – Storm Drain Design Base / Reference file E4301-X-SD01.dwg – Storm Drain Design Base / Reference file (assuming a series of files is needed – 4 character limit). 2. Naming convention for Existing XREF Items [Proj. No.]-XEX-[Discipline Designator (same as Layers)][Sequence 01 -> 99 (if needed – 4 character limit)] Example, assuming the Project Number to be E4301: E4301-XEX-SF.dwg – Existing Site Features Base / Reference file E4301-XEX-SF01.dwg – Existing Site Features Base / Reference file (assuming a series of files is needed – 4 character limit).


Chapter 11 – Plotting 11.1 CTB Files

The Port of Tacoma is currently looking at different option for CTB Files. For now, consultants can use their own CTB files.


Chapter 12 – AutoCAD & Files 12.1 Lisp & Script Files

Lisp and Script files that are used on project drawings submitted to the port are used at the contractor or A/E consultant’s discretion as long as these files do not alter the CAD Standards set forth by the Port of Tacoma. These files may be submitted along with the record drawing files as long as there is clarification on how they are used. 12.2 DGN Files

DGN files are MicroStation Design related files, and are not accepted or supported by the Port of Tacoma. For contractor’s or A/E consultants that use MicroStation, they must convert the drawing files to DWG format before submitting electronic files to the Port of Tacoma. 12.3 Database Files

Database Files that are linked to AutoCAD geometry must accompany the drawing file and reside in the same folder as the drawing file itself. 12.4 Drawing Components

A “block” is a collection of AutoCAD objects which are grouped together to form a symbol. It is treated as one entity and is stored inside the AutoCAD drawing file. An “attribute” is text information that is stored within a “block”. For example, an equipment number can be an “attribute” of a “block” symbol for a piece of equipment. That number can be extracted out to a data file for drawing information or edited, without disturbing the integrity of the “block” symbol. A “wblock” is similar to a block in that it is treated as one entity. A “wblock” differs in the fact that it is stored outside of the AutoCAD drawing file as a stand-alone drawing for insertion into other drawings. A “slide file” is a snapshot of a block that gives the viewer a quick reference to that block. “Slide files” have a “*.sld” extension.
