wireframe-under-surface("wus")

See this command in the command table.

To access this command:

Surfaces ribbon >> Operations >> DTMs >> Solid Under DTM.
Using the command line, enter "wireframe-under-surface"
Use the quick key combination "wus".
Display the Find Command screen, locate wireframe-under-surface and click Run.

Create a closed wireframe which surrounds the volume underneath the "Upper DTM" and above the "Lower DTM".

This command checks that surfaces are fully intersecting. If not, a vertical sheet is added where a full intersection isn't possible, projecting upwards or downwards to the intersection with the opposing surface. As such, output volumes from this command are always watertight.

Displays the Volume under DTM screen. Follow this link for more information and an example.
