One Triangulation Surface Volumes

This command works similarly to the Grid-based one surface volume, but using a triangulation surface (.tin, .flt) file. It differs from the Two Triangulation Surface Volumes command in the same manner that the grid-based commands do, that is, it uses a flat reference plane as the second (final) surface instead of a defined triangulation surface file. Please refer to the Two Triangulation Surfaces Volumes for more details.

Note: the volume comparison of this routine uses the selected surface file as the base surface, and the target elevation plane as the finalsurface, so be aware that if your target elevation is set primarily below the surface defined by the triangulation file, it will report as cut, when in reality you may be filling above the target elevation plane to reach the defined surface.
