Cross Sections: Creating, Annotating, and VolumesThis workbook contains exercises to creating and annotating proposed cross sections as well as computing end-area volumes along a design corridor.
In prior versions of our products, cross sections depicted an accurate representation of our modeled design as we all are generally accustom to. In the past, our cross sections tended to “drive” the design. With the advent of the OpenRoads Technology the cross sections now represent a “byproduct” of our proposed design model where the design 3D model now “drives” the design of our project.
Course DescriptionThis workbook contains exercises teaching how cross section sheets are created, annotated, and earthwork volumes are computed.
Skills Taught Create cross sections along a previously designed corridor.
Annotate proposed cross sections with Offset and Elevation.
Compute end-area volumes between sections.
Navigate Unsuitable Material, Classifications, Volume Exceptions, and other end-area volume settings.
Generate end-area volume reports including Rock and MDC.
Getting Started
This course is appropriate for any of the Bentley Civil software applications powered by OpenRoads Technology including...
Power GEOPAK or GEOPAK
Power InRoads or InRoads

Dataset UnitsBoth Imperial and Metric versions of the dataset are available. Throughout this practice workbook Imperial values are specified first and the metric values second. The metric values are enclosed in square brackets. For example: 12’ [3.4m]
Training Workspace - IMPORTANT!This OpenRoads training course uses a specific “training” workspace. The workspace includes the necessary standards including feature definitions, design standards, civil cells, and more.
The workspace can be downloaded from the link below:
Setting Up the Training Workspace (MXROAD users skip to the next section)
In this section, you will start the software and create a new user to utilize the training workspace. Selecting the proper workspace is very important within OpenRoads. This workspace contains the civil standards you need to complete the training exercises.
1. If the Civil Training Workspace is already installed, open the software as the Civil_Training user and skip to Exercise 1, otherwise continue and follow the steps below.
2. Download and install the workspace as directed in the READ ME.pdf file included with the dataset.
3. Start the GEOPAK, InRoads, Power GEOPAK, Power InRoads, or PowerCivil software.
4. Create a new User Configuration File
a. On the File Open window, click the drop-down menu for the User.
b. If Civil_Training already exists: Select the Civil_Training and skip to Exercise 1.
Start the MXROAD Software with a Workspace (For MXROAD users ONLY, others skip to the next section)
In this section, you will start the software and create a new user to utilize the training workspace. Selecting the proper workspace is very important within OpenRoads. This workspace contains the civil standards you need to complete the training exercises.
1. Unzip from the Training data set the Civil Training Workspace to C:\Bentley Training\...
2. Browse to the Civil Training Workspace User Configuration folder C:\Bentley Training\Civil Training Workspace\User-Configuration
3. Open the Civil_Training_Imperial.ucf [Civil_Training_Metric.ucf] file and ensure that the ’_USTN_PROJECT ‘ variable is set to the location where you installed the Civil_Training_Workspace. In this example, C:\Bentley Training\Civil Training Workspace.
4. Copy the Civil_Training_Imperial.ucf [Civil_Training_Metric.ucf] User Configuration file to the default Bentley MXROAD installation location depending upon the computer operating system…
For Windows XP: \Documents and Settings\All Users\Application Data\Bentley\MX V8i (SELECT Series 3)\Workspace\Users...
For Windows Vista or newer: \ProgramData\Bentley\ MX V8i (SELECT Series 3)\Workspace\Users...
5. Start the Bentley MXROAD software.
6. If the ‘Tip of the Day’ window appears, click OK to close the window.
8. Populate the Reference Attachment Settings as shown.
:
Hint: Live nesting will automatically give access to the 3D model aswell as the existing terrain dgn file.
9. Select OK to attach the reference file.
10. Dismiss the References dialog.
11. Fit View to review the project location.
12. Zoom in towards the bottom of the project to see the beginning of the alignment.
Hint: Pressing the F8 Function Key will toggle black background to white and toggle on the level override symbology. This is setup as part of the Bentley-Civil workspace. Pressing F8 again will revert back to original settings.
13. In the MicroStation pull down menu choose File > Save Settings to save the zoomed area.
14. Open the Level Display Dialog, Enable the Target Tree, and verify all levels are enabled.
Hint: Turning off a level at this stage will also turn it off in the created cross section Design Model. For a component to be displayed in the proposed cross section Design Model, the level must be turned on in the 3D model before creating the sections.
If any level settings are changed, select File > Save Settings so the changes will be remembered when cross sections are created.
1. Fit the view and then zoom into the bottom of the project to review the design.
2. Select the Create Cross Sections tool from the Corridor Modeling task menu.
3. Following the heads-up prompt, locate the alignment by selecting the red centerline alignment (GeomCL).
4. Select Preferences button from the bottom of the Create Cross Section dialog.
5. In the Preferences dialog select the preference named Sheet ‐ w/o Grid.
6. Select Load.
Preferences are predefined settings stored in the active XIN settings file for all three products (GEOPAK, InRoads, and MX). These preferences will be used for creating, annotating and computing end area volumes on proposed cross sections.
Note: Once the predefined Preferences are loaded, the end user should only need to modify items in the General tab. In the event the project requires custom cross section locations, the Custom tab allows for a multitude of settings to accommodate many different scenarios.
9. Select Apply to create the cross sections into a new DGN Drawing Model entitled Proposed XS.
It will take a few cross sections to be created. A status bar appears in the lower right corner showing the progress.
In this section, we will learn how to use the Cross Section Viewer.
1. Select the Cross Section Viewer tool from the Corridor Modeling task menu.
2. Verify the Cross Section Model setting is set to Proposed XS.
3. Set the Zoom Factor to 0.75.
4. Set the Movie Mode Time to 1.0 sec.
5. Select Run to automatically scan through the cross sections.
Hit the Esc key on your keyboard to exit the movie mode.
6. Select Cross Section 10+50 by clicking on it in the list and notice how the view updates to the selected cross section station value.
7. Press the Up and Down Arrow keys on your keyboard to step through the Cross sections in the list.
8. Close the Cross Section Viewer application.
Note that the Cross Sections are displaying an ‘X’ at each of the Crossing Features such as Centerline and Edge of Pavement. The Features must be displayed for them to be annotated, but they can be displayed at a size much smaller or using a different point symbol.
8. Using the Shift or Ctrl key on your keyboard, select all of the Crossing Features that begin with GeomCL so that they will be annotated on the cross sections as shown below.
These crossing features will be annotated with their offset and elevation as defined on the Features > General settings.
9. Expand the Segments folder and select Annotate on the left hand side of the dialog.
10. Select all of the Crossing Features that begin with GeomCL so that they will be annotated on the cross sections as shown below.
These segments will be annotated with their slope as defined on the Segments > General settings.
11. Select Apply to annotate the cross sections in the selected DGN Drawing Model labeling offsets, elevations, and slopes.
Hint: The cross section annotation labels are automatically made part of a MicroStation Graphic Group. Additionally, only the selected Features are labeled.
12. Close the Annotate Cross Section dialog.
13. Select Settings > Drawing Scale.
14. Change the setting from 1"=10' to 1"=20'. The text size is increased appropriately.
15. Return the setting back to the original setting of 1"=10' when complete.
The unsuitable material definition is added to the table at the bottom of the dialog.
11. In the End-Area Volumes dialog, complete the Classifications settings as shown below.
Note: The Cut and Fill Factor placed on the Existing Ground surface is overridden by the Compaction/Expansion leaf where Cut and Fill Factors are applied on a station range basis.
13. Define the Volume Exceptions and Added Quantities for the bridge span at stations 38+00 through 70+00
a. Select Volume Exceptions leaf settings on the left of the dialog.
b. Set the Start Station to 38+00 and the End Station to 70+00 and click Add.
c. Select Added Quantities leaf settings.
d. Set the Start and End Stations to 38+00, set the Type to Fill, enter a Volume of 11250 and a Factor of 1.2, and then click Add.
e. Set the Start and End Stations to 70+00, set the Type to Fill, enter a Volume of 3750 and a Factor of 1.2, and then click Add.
14. Select Apply.
This will complete the following five tasks when processing.
Compute end areas.
Compute volumes between sections.
Label cross sections with computed values.
Display cut and fill areas on the cross sections.
Generate a quantities report that can be formated with Style Sheets.
Create the Mass Haul diagram.
Note: When the volumes computations are complete, the Bentley Civil report browser will open when the toggle is activated. The report browser allows the designer to review the end areas as well as computed volumes for all surfaces.
15. In the Bentley Civil Report Browser, select Tools > Format Options and change the Precision of Linear and Area Units to 0.12, also change the Cubic Units precision to 0.
16. In the report Browser, change to the Volumes.xsl report available on the left.
17. Scroll down to station 38+00 in the report and notice the Added Fill of 11250, the Cut/Fill Factors being applied, and the Guardrail components being ignored.
18. Dismiss the Bentley Civil Report Browser.
19. Dismiss the End-Area Volumes dialog.
20. Pan over to the right side of the cross sections to locate the generated Mass Haul diagram.
Optional: Re-run the End-Area Volumes using a Forced Balance of Cut applied to station 54+00 and Fill applied to station 150+00. This will
create a Mall Haul Diagram that forces the bridge span to have a cumulative volume of zero.
You can delete the previous annotations and Mass Haul Diagram as they are placed on 2 distinct graphic groups. This will need to be done before running the End-Area volumes tool again.
DescriptionIn this exercise we will reference another Terrain Model in the design model, create a new cross section model that contains all surfaces, and compute the End Area Volumes.
3. Select the End Area Volume tool from the Corridor Modeling task menu.
4. Make sure to set the Cross Section Model to Substratum Cross Section on the End-Area Volumes dialog, and ensure that all 3 surfaces are checked on to compare (including Limestone).
Why is it that the Substratum Cross Section includes a Limestone surface and the River Road Cross Section does not?
Answer: The model containing the Limestone surface was referenced to the End Area Volumes.dgn after the River Road Cross Sections were created and before the Substratum Cross Sections were created.
