Using Roadway Data for Finished Ground Surfaces

Key Concepts

■

If you want to import top surface points, datum points, or custom

point codes, then you must first define these points. From the

Cross Sections menu, choose Templates

➤

Edit Template, and then

reprocess the cross sections.

■

When you import top surface data or the datum data into the

drawing, both ditch and match slope points will be imported.

■

Point codes can include centerline points, ditch points, bench

points, catch points, and so on.

You can also create a 3D grid of the roadway by selecting Cross

Sections

➤

3D Grid. Then you can use the point information in that

grid for creating the finished ground surface. Process the grid data by

using the 3D Faces option. The following illustration shows a 3D grid

of a road.
