Civil symbols provide the geometric representations of Civil objects placed in the model. You can modify the geometry and parameters of the symbols. The symbols are delivered as 2D symbol files for trenches and ditches.
Symbol icon bitmap files are also delivered for graphical previews that appear in the Catalog task and in properties dialog boxes.
You can use any shape consisting of four straight lines forming a closed contour as the symbol.
The symbols and symbol icons are delivered to [Reference Data Folder]\SharedContent\CrossSections. The symbols are also bulkloaded into the catalog. For more information, see Trench Cross-Sections Workbook.
You can associate different materials to the trench wall, footing, and slab components. Follow the steps listed below:
First, create a separate contour for each component.
Next, provide a group name for each contour.
Label each edge of the contour as shown below:
1 - Top
2 - Bottom
3 - Web_Left
4 - Web_Right
Then, merge all groups into a single group under the Simple Physical representation of the symbol.
Finally, use the GroupType settings to associate each group to a group type: Leftwall, Rightwall, Footing, or Slab.
For more information about symbol naming conventions and symbol representations, see Symbol 2D User's Guide.
Each civil symbol cross-section must have a representation named DrivenDimensions in the respective 2D symbol file of the cross-section containing Width, Depth, and InsideDepth parameters. The example defines the DrivenDimensions for a U_Shape trench cross-section.
Define the three new dimensions using the Place a Dimension Between Two Elements or Key Points from the Distance Between command. For more information, see Symbol 2D User's Guide. You can select the points or the lines. The new dimensions are shown in red in the graphic below.
Name the new dimensions with respect to their attribute names in the catalog. For more information, see Trench Cross-Sections Workbook.
Group the new dimensions to define a new representation named DrivenDimensions.
