Make User-Defined Surface
Function
This command makes a surface from the entities on the layers defined as
user-defined targets in the Define Layer Target/Material/Subgrade
command. The purpose of user-defined surfaces is for modeling surfaces
besides existing ground and design. The drawing needs to contain
entities that represent the elevations of the user-defined surface. For
example, the user-defined surface could be for alluvial soil and the
drawing has contour polylines for this surface.
There is a dialog to select which surface to make. The surface is
stored in a triangulation file that is named after the current drawing
name with the user-defined surface name appended.
This user-defined surface can be applied to Takeoff routines by running
the Set Active Surfaces command.
