Grading for the entire project is represented by one surface.
Modular Design
In the preceding exercise, you saw five design surfaces listed in Prospector, each
representing its own mini-design. The origin of these surfaces is as follows:
lots - Exterior
This surface is created from the feature lines used to grade all
the lots except those enclosed between Jordan Court, Madison Lane, and Logan

A polyline was drawn along the back edges of the lots and added to the surface
as an outer boundary. The surface was allowed to triangulate across the road and
interior lot areas. The following image shows the Lots - Exterior surface in 3D.
