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.
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.
1. Right-click in the Current Template window or click the Add menu and select Add New Component > End Condition.
1. Right-click in the Current Template window or click the Add menu and select Add New Component > End Condition.
2. In the Current Component frame:
a. Type Cut_1:4 for Name.
b. Set the Feature to Grade_Cut.
c. Set the Priority to 2.
d. Set the Target Type to Terrain Model.
e. Set the Terrain Model to <Active>.
Place the Cut_1:4 Point
1. Click on the Hinge point.
This merges the starting points of the two end condition components, forming an End Condition “tree”. Solutions are sought for each “branch”, starting with the branch with the highest Priority (having the lowest number). The component “rubberbands” indicating it is ready for the next point in the component.
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
1. Click the Test button.
2. In the Available Targets list, click <Active>-Terrain Model.
3. Click the Draw button.
4. Move the cursor in the Current Template Window.
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.
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.
Create a Solution that Adds a Cut Wall when it Encounters a 2D Wall Feature
In this section, we will ….
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.
1. Right-click on the template library object, click New > Template.
2. Rename the new template Cut Wall.
Create the End Condition Component that Seeks the Wall Feature.
1. Right-click in the Current Template window or click the Add menu and select Add New Component > End Condition.
2. In the Current Component frame:
a. Type Cut Wall for Name.
b. Set the Feature to Grade_Cut.
c. Set the Priority to 3.
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.
Note that vertical delta of 0.01. Exact Vertical faces cause challenges in terrain triangulation routines and should be avoided.
i. Right-click to Finish adding to the component.
5. Test the template.
6. Save the Template Library.
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.
Create a Solution that ties into the terrain at the Right of Way Line
In this section, we will ….
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.
1. Right-click on the template library object, click New > Template.
2. Rename the new template Forced ROW.
Create the ROW Solution. First, add the End Condition Component seeking the ROW horizontal location.
1. Right-click in the Current Template window or click the Add menu and select Add New Component > End Condition.
Note that this Component will not show up in the final model: choose Names and Feature Definitions that “self-document” their purpose.
c. Set the Priority to 2.
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
1. In the Dynamic Settings dialog,
a. Ensure that the Apply Affixes box is clear.
b. Select a Point Name of HINGE.
The Point Style should automatically be set to Grade_Hinge.
c. Select the Precision Input Mode of xy=
d. Type 0,0 and click the Enter key.
The Hinge point is placed and the component is “drawn” to the cursor, awaiting the next point.
2. In the Dynamic Settings dialog, we want to infinitely seek and place a point if we find the wall feature:
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.
1. Right-click in the Current Template window or click the Add menu and select Add New Component > End Condition.
2. In the Current Component frame:
a. Type Cut_At_ROW for Name.
b. Set the Feature to Grade_Cut.
c. Set the Priority to 2.
d. Set the Target Type to Terrain Model.
e. Set the Terrain Model to <Active>.
We have just instructed our component to target the active terrain above the 50% slope (= steeper than 50%).
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.
2. In the Current Component frame:
a. Type Cut_to_ROW for Name.
b. Set the Feature to Grade_Cut.
3. In the Dynamic Settings dialog,
a. Ensure that the Apply Affixes box is clear.
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.
6. Test the template.
Create the Cut_1:2 End Condition Component.
1. Right-click in the Current Template window or click the Add menu and select Add New Component > End Condition.
