Breaks a multi-layer wall or arc into two parts.

         1.* (IND) mwall to break

         3.* (POINT) breaking point
         4.* (Y/N) close wall ends ?

Description
This command breaks a multi-layer wall or arc into two parts at a
given point. When a wall is broken into two, the wall's slope is kept.
The break is always at right angles to the wall or radial to the arc.

If a three dimensional projection of the wall is displayed it will be
erased, but may be restored by using \mw3d (several walls) or \wal3d
(an individual wall).

Indicate and confirm the wall to be broken. Specify the point at which it is
to be broken. If the specified point is outside the wall, the system will
assume a point on a projection perpendicular to the wall from that point.

The wall end at the breaking point may be closed or left open.

You are prompted to indicate other walls to break until you enter
another command.

If the walls are not closed, the breaking point will be indicated
by a short help line.
