3D Entity by Surface Model

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.
