Make Overexcavate Surface From Existing/Design
Surfaces
The Initialize Overexcavation Surfaced dialog box shown here allows
the user to select which surface model to overexcavate and to enter
in the depth value for the desired adjustment. Use the Min
Existing/Design option to set the overexcavate as the minimum of
the existing and design surfaces. If a single surface is selected
the value entered will be applied to that surface only. The
resulting surface of Make Overexcavate Surface is stored in a
triangulation file that is named with "-ox" appended to the current
drawing name.Prerequisite: Existing and/or
