Before you Begin

This training session will utilize the sample workspaces provided in the OpenRoads products to facilitate loading of necessary libraries used in the exercises. You may use Bentley Civil Imperial or Bentley Civil Metric workspaces as appropriate to the supplied dataset.

For information, the configuration loaded above and beyond the civil settings are:

Sample node and conduit feature definition libraries

CIVIL_CONTENTMANAGEMENTDGNLIBLIST > $(_USTN_PROJECTDATA)/dgnlib/Sample Drainage FeatureDefs*.dgnlib

CIVIL_CONTENTMANAGEMENTDGNLIBLIST > $(_USTN_PROJECTDATA)/dgnlib/*Conduit Library.dgnlib

The utility libraries also contains the levels, element templates and additional line styles needed for utilities.

MS_DGNLIBLIST > $(_USTN_PROJECTDATA)/dgnlib/Sample Drainage FeatureDefs*.dgnlib

MS_DGNLIBLIST > $(_USTN_PROJECTDATA)/dgnlib/*Conduit Library.dgnlib

Cell libraries are loaded by virtue of the civil workspace wildcards. The utility cell libraries are collocated with the road/site libraries.

Note for MXROAD users only:

The data supplied includes MXROAD projects, in metric units, which have been created using the “Tutorial” project settings file. When the classes ask you to open a design file (.dgn), MXROAD users will first need to open the existing project in the appropriate data folder, by selecting the MX project file (.mmd) as usual. The appropriate design file can also be selected on the MX Project Startup dialog:


If you do not have the “Tutorial” project settings file installed, then you can create a new project instead, using your default project settings file for metric units, and choose not to overwrite the model file.


Lesson 1 - Importing an existing Drainage Project

Course Description

In this lesson, we will review the location and function of the Subsurface Utility Engineering tools and review the data which will be used for a start point of our utilities model. This reference data consists of an existing ground surface, and surfaces designed in a road or site workflow.


Open and Review Base Files

1. Instructor will guide you which product to use and the exact path of the data.

2. Open …\Lesson 2\Design Centerline.dgn


3. DGN files contains:

a. In 2D model:

i.Geometry for a road design project

ii.Corridor for the road main line.

iii.Site type design elements for a side road and a pond

b. In 3D model

i.Existing ground terrain.

ii.Proposed surfaces for the roads and pond. In this case, these elements are OpenRoads corridor and site elements but they could be terrain model surfaces as well.


Review Subsurface Utility Engineering Tools

1. The Subsurface Utility Engineering tools are located in the top menu.

2. They are also located in Task Navigation, which is where we will reference them in remainder of this document.


3. Subsurface Utility Engineering is a task workflow, thus when opened you see the complete Subsurface Utilities toolset but also a collection of other tools from MicroStation and OpenRoads to provide complete workflow coverage. The highlighted panels below are the Subsurface Utility Engineering tools. The remainder are MicroStation or other OpenRoads tools.

4. Subsurface Utility Engineering Menu

a. Project > Import - import of drainage networks from various sources.

b. All other tools in menu are same as description in task navigation below.


5. Subsurface Utility Engineering > Components tasks (left to right)

a. Place Node - Creates a node structure. Example, catch basins, manholes, valves, etc.

b. Place Link Between Nodes - Creates a link (conduit) between two nodes.

c. Extract Utilities from Graphics - Creates links (conduits) from graphical elements. Graphical elements may derive from survey operations, geometry constructs or MicroStation workflows. Example use cases are:

i.Create models of pressure lines such as water or gas lines, existing or proposed.

ii.Create drainage networks from surveyed nodes and pipes.

d. Utility Feature Manager - used to configure the filters used with Extract Utility From Graphics command

6. Subsurface Utility Engineering > View tasks

a. Top row left to right

i.Open Profile Model - same as OpenRoads command - used to open profile of utility links.

ii.Open Cross-section View - same as OpenRoads command - used to open cross-section view.

b. Second row

i.Element Symbology - Used to configure resymbolization settings used in Analytic View

ii.Tool tip Customization - used to configure user defined tool tips which are shown when cursor hovers over a feature.

iii.Flex Tables - opens the Flex Table Manager where flex tables can be managed and opened.

iv.Utilities Properties - Opens the Utility property panel. Properties are also available from context toolbox.


c. Third row

i.Network Navigator - provides ability to step through components of a utilities network for review.

ii.Queries - Provides ability to define custom queries against the utilities data.

7. Subsurface Utility Engineering > Tools

a. Model Builder - Manages 2 way data link between a Subsurface Utility model and a spatial database

b. Publish Utility I-model - publishes an i-model of only utility features with user selected attributes.

c. User data Extensions - allows custom attributes to be managed and applied to utility features

d. Compact Database - allows compaction of data, which can become bloated if many deletions are made. Note: compaction occurs automatically (with prompt) at prescribed intervals.

e. Synchronize Drawing - Will synchronize the dgn elements to data. Not often needed as this is automatically managed. But in some rare circumstances it may be necessary.

f. Clash Detection - finds clashes between utilities and any 3D features. Clashes are marked with a conflict node which can be managed and reported like other nodes.

g. Selection Sets - Allows creation, and reuse, of repeatable selection sets for reporting, editing or any other purposes.


Review Context Toolbox for Subsurface Utility Engineering Features

1. The Subsurface Utility Engineering tools use the same heads up interface as OpenRoads. The commands we will use in the remainder of this document will emphasize the heads up prompting and context tool boxes.

2. If you select a link feature then the context toolbox adds additional tools to the context toolbox.

3. For node features Utility Properties is added to the context tools normally available for OpenRoads point features.


Release 1 Workflow

You may have noticed from the review of the tools above that there are no tools for performing hydraulic analysis. Release 1 (The original release with OpenRoads SELECTseries 3 Refresh) will be focused on 3D modeling and Subsurface Utility Engineering workflows only. As such, users will need to rely on existing tool sets for hydraulic analysis.

The workflow will be as follows:

1. Use GEOPAK Drainage, InRoads Storm and Sanitary, or MXROAD Drainage Design to layout the drainage (or sanitary) network.

2. Use the same tools or a Haestad product for hydraulic analysis.

3. Use GEOPAK, InRoads or MXROAD for annotation and plans production.

4. Import the gravity networks into Subsurface Utility Engineering for modeling.

5. Use the other Subsurface Utility Engineering tools for modeling of other utilities.


Lesson 2 - Import Drainage Projects

Course Description

This lesson contains information on importing a drainage project from a legacy format.

This lesson is applicable for importing from GEOPAK Drainage, InRoads Storm and Sanitary and MXROAD Drainage Design.

Skills Taught

Importing an existing Drainage Project


Import Drainage Project

In this section, we will demonstrate the process for importing and existing Drainage Project.

1. Open …\Lesson 2\StormDrainage.dgn. The road design information is attached as reference.

2. Start command Subsurface Utility Engineering > Project > Import. You will choose the import item which matches the running OpenRoads product.


3. Choose the file named …\Lesson 2\DrainageProject.*. The extension will vary based on product.


NOTE: For MXROAD only a second dialog is displayed. Check that the path to the Project Styles folder is pointing to the project's \styles folder, then click OK.


4. Once the project is imported, you will see the nodes and pipes in both 2D and 3D models.

5. You may wish to turn off the display of Design Centerline reference file in 3D so you can better see the storm water elements. You will notice the following:

h. If there is a feature definition found which matches the legacy library item name then the feature definition is assigned during import. Thus, our catch basins have a feature definition assigned.

i. Otherwise, the nodes and pipes are assigned active symbology.

j. Nodes and pipes are shown in plan space in 2D. This plan space and corresponding profiles are the normal editing areas.

k. Nodes and pipes are also modeled in 3D. Some edits can be performed in 3D.


Lesson 3 - Edit Storm Drainage Model

Course Description

In this lesson, we will explore some methods for editing data in the storm drainage network. The workflow to imagine here is that we have imported the drainage data, which will be field verified and then corrected as needed. We will explore some common edits that might be required when field verifying model data such as:

Skills Taught

Correct a pipe size

Correct a top or invert elevation

Correct a feature definition

Move a node and pipe


Editing Storm Drain Model

In this section, we will edit an existing Storm Drainage Model.

1. Open …\Lesson 3\StormDrainage.dgn. The appearance of the file has been adjusted a bit by turning off some features.

2. Change a pipe feature definition: Select one of the pipes in plan space. Open Quick Properties

3. There were no matching Feature Definitions found when we imported so the pipes have none assigned. In the Feature Definition property, choose Storm Sewer/Storm Sewer Circular RCP. Note that you can multi-select several pipes to adjust feature definition.


4. Once the Feature Definition is assigned, go back to quick properties and notice that we now have access to all the pipe sizes defined for Storm Sewer Circular RCP. When we changed thee feature definition the pipe size was set to the closest matching size in the feature definition table. Experiment with changing the sizes. Note that you can multi-select several pipes to adjust feature definition.

5. Move a node: Select the node which lies in the middle of the intersection.

6. The center dot manipulator can be used to move the node. Using this manipulator and Civil AccuDraw, reposition the node to about station 150+00 [45+70] and offset of 36ft [10.7m]. Notice that we can adjust the top elevation at this same step:

a.You can type a known elevation

b.Or by press the ALT key, you can rule the node to a new surface. Press ALT, then select the surface.


7. The node and connecting pipes will update in 2D and 3D.

8. Using the arrow manipulators, adjust the rotation of the node as needed. You should notice that if Civil AccuDraw is still active then it will assist in getting a 90 degree rotation from the centerline.

9. Select the same node and choose Properties from the context toolbox. In the Quick Properties, you can also edit elevations.


10. Change pipe connectivity: For the two north south pipes, the model will be more realistic if we connect them to the side faces instead of the back face. Select the pipe, then using the dot manipulator, drag it to the side face. You will see a small orange plus sign when you get near the connection regions.

11. Select the pipe which crosses the street and connects to the node we moved.


12. Drag the handle on right and reconnect to next node downstream.


13. Review the 3D model at the node near intersection.

14. Change node Feature Definition: Select the node we moved and change the feature definition to Inlet C. Using this or other nodes, experiment with other feature definitions for nodes. You will see that a high level of detail is possible.


15. Note that when changing feature definitions a rotation edit might also be needed. This is due to differences in how the 3D cells in the libraries were created.


Lesson 4 - Add Storm Drainage Features

Course Description

In this lesson, we will explore how to add nodes and pipes to the storm drain model.

Skills Taught

How to place Nodes

How to place Links


PLACE FEATURES

In this section, we will show the placement of Nodes and Links in a Drainage Model

1. Open …\Lesson 4\StormDrainage.dgn

2. Start the Place Node command.

3. Select feature definition to CB#12 5X5 in the command dialog, as shown below.


4. The first prompt is to pick the reference element. This can be any 3D element in our model and is used to set the top elevation of the node. In this instance, the node needs to be placed under the curb of the side road. Pick the curb solid of the side road. You will note that you can forego the pick of an elevation source and define the elevation directly.

5. Then in the plan space, DP to place the node. Use Civil AccuDraw to place the node at station 0+65 [0+20] and offset of 14ft [3.65m].


6. The last prompt is to define the rotation.

7. Place a second catch basin along the side road at about station 1+30 [0+45] and 14 ft [3.65m].

8. While the command is still active, change the Feature Definition to Headwall A

9. At the prompt for elevation reference element, click Reset to allow entering a specific elevation.


10. Use 1071 ft (328 m) for the elevation and place the headwall in the pond.

11. Start the Place Link Between Nodes command.

12. Set the feature definition to Storm Sewer Circular RCP and size to 18" (450mm).


13. Follow the prompts and place pipes between the nodes placed above. Notice how the connection regions in the nodes control how the pipes connect.

14. Select one of the links in plan space.

15. On the context toolbox, select Open Profile Model.


16. Pick the view to show profile.

17. Select the pipe in profile and you can edit the slope and elevations of the pipe.

18. The pipe profile edits are reflected in the model.

19. You can also edit pipe slopes and elevations directly in plan view. Select the pipe and then when your cursor passes over the drag handle at the end of pipe, you'll see two additional manipulators appear.

a.The right triangle shaped manipulator allows editing of pipe slope from plan view.

b.The isosceles shaped manipulator allows editing of the pipe invert elevation.


Lesson 5 - Model a Utility Line From 2D Feature and Terrain Model

Course Description

In this lesson, we will create a model of an existing utility line by draping a 2D linear element on a terrain model. The utility feature might be a pressure conduit such as a water line, or represent a generic conduit such as ductwork or cabling.

Skills Taught

Creating utilities from graphical data

Viewing utility profiles


Model Utility From 2D Features

In this section, we will explore creating utilities from 2D features

1. Open …\Lesson 5\Surveyed Utilities.dgn. This is a 2D DGN which contains a terrain in a 3D model.

2. Start the Extract Utilities From Graphics command.


3. If you get a prompt asking to create a hydraulic model then answer yes.

4. We will start with modeling some water lines. Set Feature Definition to Water Line Ductile Iron and set size to that which matches the surveyed water line you will be picking.

5. First Prompt, use Selection Method.

6. Pick the one of the water line linear elements.

7. Reset to stop picking.


8. Select the existing ground terrain model for elevation basis

9. Enter -3.00ft [-1.0m] for the vertical offset (note that this is a negative value).

10. Since this is an existing utility line then a trench is not needed.


11. Water line is modeled

Notes:

We could have selected multiple elements at once in step 6 above.

Using utility filters, we could have extracted multiple features of different sizes and different feature type all at once.

If our graphic features were 3D, then the terrain model is not necessary. The user has option to use the 3D element elevations. This is covered in next lesson.

12. Select the Water Line (in 2D or 3D) and in context toolbox choose Open Profile Model


13. Open or select a view for profile display

14. The water line profile was created by drape on a terrain model with a best fit as the designated depth. Using best fit provides a smooth profile which is more true to life in most circumstances.


15. Select the profile (double blue lines) and open Element Information to review how the profile is computed.

16. At this point, the designer can change the profile in any of the ways allowed by the OpenRoads profile tools, including:

a.Edit the best fit parameters

b.Convert the best fit to a PI rule and then edit the result

c.Make a new profile and set it to active.

17. Using your knowledge of the OpenRoads profile tools, make a new profile for the water line and set it to active. You'll notice that the 3D model follows the active profile as expected.
