Command Overview

Generate a digital terrain model (DTM) wireframe from a series of strings. This command has the following capabilities:

Choice of full object input and/or individual strings and points
Ability to create dtm attributes from input data attributes
Optional creation of spur strings to avoid plateaus on ridges and valleys
Optional automatic best-fit DTM plane in addition to world and view plane options
Automatic nesting of boundary limit strings

Boundary Strings

Care should be exercised when creating a DTM using view coordinates rather than world (XY) coordinates.

For example, if the plan view is in use, but the view direction is set to a significantly different orientation, unexpected results can occur. For this reason, if you have configured a view direction with this type of deviation from the world plane, particular care should be taken in the definition of inner/outer limit strings.
