Description
Creates 3D solids by thickening surfaces, their faces, faces of 3D solids, regions and wire entities by specifying the thickness value.
The following wire entities are accepted: lines, polylines, circles, ellipses, arcs, helices, splines.
Note: If you thicken a multi-face surface of several adjacent
                    faces of one 3D solid/surface, then the corresponding faces remain adjacent on
                    the opposite side of the new 3D solid(s). This differs the DMTHICKEN command
                    from DMEXTRUDE.
            Note: When a wire entity is selected, a circle with the radius
                    of the specified thickness value is swept along the wire.
            Options
- SIngle side
 - Adds the thickening in the specified direction.
 
- Both sides
 - Adds thickening in both directions.
