Cancels the 3-dimensional model of all multi-layer wall entities leaving
2-dimensional multi-layer wall entities.

      if 3D multi-layer wall arcs exist:
         1. (Y/N) keep 3D display of arcs ? <y>
      if 3D "irregular" multi-layer walls exist:
         2. (Y/N) keep irregular 3D display ? <y>

Description
This command cancels the 3-dimensional projection of multi-layer wall
entities, i.e., walls, arcs, and openings.

The 3D model may be recreated by executing \mw3d (all walls) or \wal3d (single
wall) again.

After using this command, all 3D multi-layer wall arcs that have been changed
(by sectioning, projection, etc.) from their original attributes will be
restored with their original attributes when the \mw3d command is executed.
Similarly, 3D irregular walls will also be restored with their original
attributes.  You are therefore asked if you wish to keep 3D wall arcs and 3D
irregular walls (if such exist in the model).

Initially, every 3D wall element possesses six faces.  If you execute any
operation on the wall, such as sectioning, which causes it to have more than
six faces, the wall becomes an "irregular" solid.

If you reply `y' to these two prompts, all 3D walls except "irregular" or arc
walls will be cancelled.
