An engineer has come into a set of InRoads Cross Sections and drawn a line in each section to represent a bedrock layer in the ground. Can you extract these graphics to create a DTM for a bedrock surface?
We need to add a surface to the cross sections first, then we can extract the surface to create the physical DTM with triangulated features. The features will be a transverse line at the stations represented in the cross section set.
1. Add all the graphic line into a selection set in MicroStation.
2. Go to Evaluation > Cross Section > Add Surface to Cross Section
3. Next we need to extract the graphics to create the physical surface from the cross section surface. Go to Evaluation > Cross Section > Cross Section to Surface.
You now have a DTM generated from the manually drawn graphics in the cross sections.
