This command allows you to assign elevations to one or more
polylines. The command also affects lines, arcs, circles, inserts
and points as well as polylines. The elevation can be assigned by
entering the value or by picking an existing object or text entity
that has the desired elevation. Note that this will change 3D
objects to a single target elevation (making it a 2D object) as
well as changing elevation values of 2D objects.
