Trimmed Planar Surfaces
A planar surface may be constructed from lines, arcs, splines, polylines, or
simply two locations, if the selected objects are closed and on the same plane.
The exterior shape of the 2D wire shape becomes the trimmed edge of the
surface. In this exercise, you create trimmed planar surfaces.
