This command assigns the elevations of the selected points,
inserts, lines and polylines to the elevations defined by the
specified grid (.GRD) or triangulation (.FLT, .TIN) file. For lines
and polylines, additional vertices are added to model the surface.
3D Polylines cannot have arcs, so any arcs in the original 2D
polylines are converted to a series of chords. This command is
useful to "drape" objects onto a surface and to easily update them
if they are moved to a different location on the surface later by
executing the command again.
