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

Bentley MX ROAD

PowerCivil for {country}

Dataset Units

Both 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]

Prerequisites

This class assumes that you have a working understanding of templates, including Testing End Conditions. These topics are covered in the Templates - Using and Editing class.


Build a Multi-slope End Condition

In this section, we will ….

Launch the software in the Bentley-Civil Workspace and open the class template library.

Build a Multi-slope End Condition targeting the Active Terrain.

1. Launch InRoads, GEOPAK, or MX (or their respective Power versions).

2. Open the Templates.dgn file in the appropriate workspace:

User: examples

Project: Bentley-Civil-Imperial [Bentley-Civil-Metric]

Interface: Bentley-Civil

The Bentley-Civil workspace is delivered with the software as a fully configured environment ready for immediately use in a production environment. All Bentley Civil training uses this workspace. To use this workspace, the User and Project Settings in the MicroStation File Open dialog must be selected as described above.

Note: the datafiles can be installed anywhere. This book assume the files are in C:\Bentley Training\End Conditions\.

3. Open the Create Template dialog by clicking Tasks > Civil Tools > Corridor Modeling > Corridor Creation > Create Template

The Create Template dialog opens the Template Library designated by the CIVIL_ROADWAY_TEMPLATE_LIBRARY environmental variable:

1. In the Create Template dialog File menu, select Open


2. Browse to and select the project template library in the class data folder: Defining Side Slopes.itl [Defining Side Slopes - Metric.itl].

Note: Unless the CIVIL_ROADWAY_TEMPLATE_LIBRARY workspace variable is changed, you will have to open the project template library manually every time you open the software.

The templates we create are not just about geometry. Corridor Modeling gives the components and points a longitudinal dimension; they become the permanent model which has a very long shelf life and gets passed to many people. The components and 3D linestrings need to have valid Information Modeling value. In this class we will build Templates with 1) good geometry and 2) good Information Modeling.

Create a Multiple-Slope Solution targeting the Active Terrain

1. Right-click on the template library object, click New > Template.

2. In the new template name, type Cut and Fill.

Create the Cut_1:2 End Condition Component.

e. Select a Point Name of CUT.

The Point Style should automatically be set to Grade_CutLine

f. Provide a more descriptive Point Name (type Cut_1:2 or Cutline w Ditch (whichever seems more clear to you or your team)).




The final daylight point is placed and the component is “drawn” to the new cursor position, awaiting the next point. Note that the drawn length is irrelevant to the engineering since the End Condition is Infinite box is set.

Test the Template





5. Verify the template solves only during the final 50% Cut segment

Add Parametric Constraints to the Ditch Geometry so that it might be Controlled by Corridors

Ditch geometry varies not only from project to project and from ditch to ditch within a project, but may often vary along the length of the ditch. An oversized ditch takes up a lot of width. Defining Parametric Constraints on the Ditch Points allows shrinking or expanding the ditch to meet minimum hydraulic requirements while taking up the least amount of footprint. Corridors can adjust these Parameters station by station.

1. Double-click the DITCH_FORESLOPE point.

2. In the Point Properties dialog

a. Type Ditch_Foreslope_Slope for the Slope Constraint Value.


b. Type Ditch_Foreslope_Width for the Horizontal Constraint Value.

c. Click Apply.

d. Close the dialog.

3. Double-click the DITCH_BOT point.


a. Type Ditch_Bottom_Slope for the Slope Constraint Value.

b. Type Ditch_Bottom_Width for the Horizontal Constraint Value.

c. Click Apply.


5. Double-click the DITCH_FORESLOPE point.


a. Type Ditch_Backslope_Slope for the Slope Constraint Value.

b. Type Ditch_Backslope_Width for the Horizontal Constraint Value.

c. Click Apply.


We will not do so here, but if you think the interior berm might vary along the corridor, Parametric Labels may be added for the DITCH_TOP point.


Copy, Rename and Prepare the “Full” End Treatment

1. Right-click on the Cut and Fill template, click Copy.

2. Right-click on the Cut and Fill template, click Paste.

3. Right-click on the new Cut and Fill1 template, click Rename.

4. Type Fill and Cut with Ditch.

5. Double-click it to make it the Current Template.

6. Delete the 50% Cut component (right-click on it, select Delete Component).

Drag in the Cut Ditch and Test

1. Click on the Cut Ditch Interior template, drag it into the Fill and Cut with Ditch template.

2. Make sure the hinges merge.

3. Test the template.


Priority Conflicts

1. If the Priorities were typed in as per the workbook’s instruction, an occasional result of a merge will occur here: component having the same Priority:

If you do not get this dialog, Test normally. Verify that the template solves as intended.

2. If you get the Priority Conflict dialog, click OK to continue.

3. In the Test End Conditions dialog, click the Check Priorities button.

The End Condition Priorities dialog lists all the Points with End Condition Components with identical priorities.


4. Click Edit.

The Fix Priorities dialog lists all the components starting from the point and their priorities.

5. Change the Priority of the Cut Ditch Interior to something other than 1, 2 or 8.

h. Set the Target Type to Terrain Model.

i. Set the Terrain Model to <Active>.

Place the non-seeking Clear Zone width Point









2. In the Dynamic Settings dialog, we want to go horizontally to the full Clear Zone width, without seeking:

a. Clear the Check for Intersection box.

This disables the Place Point at Intersection box.


c. Set the Do Not Construct box.

d. Select a Point Name of DNC.

The Point Style should automatically be set to Draft_DNC (DNC is old term meaning Do Not Construct).


f. Type 18,0 [6,0] and click the Enter key.

The non-constructing point is placed and the component is “drawn” to the new cursor position, awaiting the next point.


g. Note that the line segment is not drawn from the Hinge to the DNC. This is due to Do Not Construct setting on the DNC point.

Place the Point that Targets the Ground in Cut

1. In the Dynamic Settings dialog, we want to target the ground, but only in a limited range:





e. Select a Point Name of CLEARZONE_CUT.



f. Select the Precision Input Mode of dl= (delta).

g. Type 0,3 [0,1] and click the Enter key.

h. Right-click in the Current Template Window and select Finish.

The “surface segment” runs directly between the HINGE and the CLEARZONE_CUT point.

i. Test the template.

The template should solve to the Clear width only between “level” and a 1:3 Cut slope.

Create the ClearZone_Fill End Condition Component.


This is identical to the ClearZone Cut solution, with the exception of the seek direction.

The Point Style should automatically be set to Draft_DNC (DNC is old term meaning Do Not Construct).


f. Type 18,0 [6,0] and click the Enter key.

The non-constructing point is placed and the component is “drawn” to the new cursor position, awaiting the next point.


g. Note that the line segment is not drawn from the Hinge to the DNC. This is due to Do Not Construct setting on the DNC point.

Place the Point that Targets the Ground in Cut

1. In the Dynamic Settings dialog, we want to target the ground, but only in a limited range:





e. Select a Point Name of CLEARZONE_FILL.

The Point Style should automatically be set to Grade_FillLine.

f. Select the Precision Input Mode of dl= (delta).

g. Type 0,-3 [0,-1] and click the Enter key.

h. Right-click in the Current Template Window and select Finish.


The “surface segment” runs directly between the HINGE and the CLEARZONE_FILL point.

i. Test the template.

The template should solve to the Clear width only between a 1:3 Cut slope and a 1:3 Fill slope.


Create a Solution that Adds a Cut Wall when it Encounters a 2D Wall Feature


Create a Cut End Condition that draws a Wall when it encounters a 2D Wall Feature

Add a Wall Shape to the Wall Solution

Assemble a Template that solves for Cut with and without a wall feature

Wall, when used along a Corridor, tend to be intermittent features. We will build a cut template that ties into the active terrrain at a (maximum) slope if it does not find a 2D wall feature. If it does, it will draw the (maximum) slope to the horizontal location of the 2D wall feature and then draw a near-vertical wall face segment to the active terrain.


2. Rename the new template Cut Wall.

Create the End Condition Component that Seeks the Wall Feature.



a. Type Cut Wall for Name.



d. Set the Target Type to Feature Definition Horizontal.

e. Set the Feature Definition to Struc_WallPerch.

We have just instructed our component to target the horizontal location of any feature with a Feature Definition of Struc_WallPerch.


Place the Hinge and Wall Perch Points








2. In the Dynamic Settings dialog, we want to infinitely seek and place a point if we find the wall feature:





e. Select a Point Name of WALL_PERCH.

f. Set the Point Style to Struc_WallPerch.



i. Right-click to Finish adding to the component.


3. Test the component.

a. In the Available Targets list, click Struc_WallHoriz-Feature.

b. Click Draw.

c. Move the cursor and observe that the slope ends at the horizontal location of the feature.


Create the End Condition Component that Seeks the Active Terrain.



a. Type Cut Wall Face for Name.

b. Set the Feature to Structure_Wall




We have just instructed our component to target the Active Terrain.

3. Place a point at the Hinge point, ensuring a merge.

4. In the Dynamic Settings dialog, we want to infinitely seek and place a point at the active terrain:






e. Select a Point Name of WALL_TOP.

f. Set the Point Style to Struc_WallTop.

g. Select the Precision Input Mode of dl=

h. Type 0.01,5 [0.01,3] and click the Enter key.

Note that vertical delta of 0.01. Exact Vertical faces cause challenges in terrain triangulation routines and should be avoided.




Add a Wall Shape to the Wall Solution

End Condition Components cannot be closed shapes, but closed shapes must be used for volumes purposes. In this next section we will add a previously-created wall shape to the Wall End Condition.

1. Review the Wall Shape template in the Components folder.

2. Move the WALL_TOP point and observe the results.

3. Double-click the Cut Wall template to make it Current and Editable.

4. Click on the Wall Shape template and drag it into the Cut Wall template.


5. Make sure the WALL_PERCH points merge.

Next we need to have the Wall Structure top be controlled by the End Condition point.

6. Right-click the top front point of the wall shape, WALL_TOP1. Click Add Constraint > Vertical.

Note: any point dragged in that has a name duplicated in the Current Template will have a suffix added to maintain unique point names.

7. At the “DB: Select Parent Point, RST: Exit” prompt, click the Wall_Top point.

8. Set the Vertical Offset to 0.

9. Click OK.


The wall shape should adjust with wall face component. Note that the shape is always showing when it should be dependent on the end condition success.

We need to make the Wall Shape component a child of the Wall Face End Condition. This way the wall shape will not show unless a cut wall is needed.

1. Double-click on the Struc_Wall component (the wall shape).

2. In the Component Properties dialog,

a. select Cut Wall Face as the Parent Component.

b. Click Apply.

c. Close the dialog.


Create a Solution that ties into the terrain at the Right of Way Line


Create a Cut End Condition that ties into the active Terrain at the Right of Way Line

Create a Cut End Condition component that ties into the active Terrain at 50%

Provide a Cut solution that ties in at 50% or at the Right of Way line if the ROW lines is inside the 1:2 Cut Daylight line.

Sometimes the allowable limits of construction lie within the steepest standard allowable slope. For example, tying in directly to the Right of Way line may be required when the 50% slope solution is exceeded. In this section we will build a template that

solves for a 50% cut slope, unless

the 50% cut slope lies outside the ROW line, then

it will solve directly from the Hinge to the surface at the Right of Way line

The way to solve for this, in End Condition logic, is:

Seek a solution where the ROW feature exists and the surface lies above the 50% cut line

If that fails, solve with a regular 50% cut solution.


2. Rename the new template Forced ROW.

Create the ROW Solution. First, add the End Condition Component seeking the ROW horizontal location.




a. Type Check_for_ROW for Name.


Note that this Component will not show up in the final model: choose Names and Feature Definitions that “self-document” their purpose.


d. Set the Target Type to Feature Definition Horizontal.

e. Set the Feature Definition to Geom_ROW.

We have just instructed our component to target the horizontal location of any feature with a Feature Definition of Geom_ROW. If the component fails to find a ROW line, there is no right of way line, the component and the component “branch” fail.

Place the Hinge and ROW_Horiz Points








2. In the Dynamic Settings dialog, we want to infinitely seek and place a point if we find the wall feature:




d. Set the Do Not Construct box.

e. Select a Point Name of ROW_at 1:2.






Now add the End Condition Component seeking the Active Terrain above the 50% line at the ROW location. If this component is activated it means that the ROW line was found. If this component fails to find the existing ground, then it means the surface is below the 50% slope threshold.



a. Type Cut_At_ROW for Name.





We have just instructed our component to target the active terrain above the 50% slope (= steeper than 50%).

Place the Hinge and Cut_ROW Points



b. Place a Point at the ROW_at 1:2 point.







e. Select a Point Name of Cut_ROW.


g. Select the Precision Input Mode of dl=

h. Type 0,2 [0,2] and click the Enter key.


Add a Component between the Hinge and the CUT_ROW Point.

Because the ROW_HORIZ point is set to Do Not Construct, neither End Condition will display because only one point in each is drawn. We will add a Component between the Hinge and CUT_ROW point.

1. Right-click in the Current Template window or click the Add menu and select Add New Component > Unconstrained.


a. Type Cut_to_ROW for Name.




b. Place a Point at the HINGE point.

c. Place a Point at the CUT_ROW point.

d. Right-click to Finish adding to the component.

4. Double-click on the Cut_to_ROW component.

5. For Parent Component, select the Cut_at_ROW component.

We want to make the display of the Grading component conditional on the success of the ROW solutions.






e. Type Cut_1:2 for Name.

f. Set the Feature to Grade_Cut.

g. Set the Priority to 5.

h. Set the Target Type to Terrain Model.

i. Set the Terrain Model to <Active>.




b. Place a Point at the HINGE point.

The component is “drawn” from the Hinge to the cursor, awaiting the next point.

c. Set the Check for Intersection box.

d. Set the Place Point at Intersection box.

e. Set the End Condition is Infinite box.

f. Clear the Do Not Construct box.

g. Select a Point Name of Cut.


h. Edit the Point Name to Cut_1:2.

i. Select the Precision Input Mode of hs=

j. Type 8,50% [3,50%] and click the Enter key.


k. Right-click to Finish adding to the component.

4. Test the template. Verify that it solves in all cut situations:


Cut - No ROW Feature

Cut at 50% with ROW to the outside of the daylight

Cut at the Surface at the ROW feature, inside the 50% daylight point.

Optional: to make this template more easily used at other “Maximum” Slopes (such as 1:1):

1. Edit the CUT Point and ROW_HORIZ points: Type Max_Slope for the Slope Constraint Label.

2. Verify by changing the value of the Max_Slope Parametric Constraint and Testing the template.
