Description:
This command modifies walls. You may stretch walls while breaking them or move
them while cutting or changing their length.
You are asked to select an option:
Option `b'will break an indicated wall. The break point may be located on the
wall axis (in which case the wall does not move) or remote from it. The latter
case will stretch the two parts of the original wall to the break point. (See
\break command.)
Option `c'will cut an indicated wall. You are prompted to indicate two cut
points  the start and end of the cut. When both points are located on the wall
axis the wall is cut but is not moved. When the two points are remote from the
wall the two parts of the original wall will be stretched to these cut points
and there will be no wall between the two cut points. (See \wcut command.)
Option `s'will modify the indicated wall end point. The new end point need not
be aligned with the wall. The wall may be stretched (or shortened) in any
direction. (See \wshrt command.)
