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.
