Creates a multi-layer wall between two points.

        1.   (POINT) first wall point
        2. * (POINT) next wall point (Alt+1-symmetry, Alt+2-alignment)

Description:
This command creates a wall between two points. The wall must first be
selected from the pull-down graphic walls library using the \setmw command. If
during the current work session you have already selected a wall type, this
will remain the default wall type whenever you use this command.
Pick the first point of the wall. From this point the system will "stretch"
an elastic wall to the current cursor location, while you pick subsequent
points. You are prompted for additional points until you enter a new command.
Each additional point creates another wall segment connected to the end of the
previous one. The wall corners are resolved by the system.
NOTE: Only if the current point meets the first point, will that corner be
resolved.
The line connecting the previous point to the current cursor position is known
as the "base" line. It represents the first defined surface of the wall unless
the alignment of the axis has been changed.
Symmetry
When working with asymmetrical walls you may find that the wall, as it
appears, is "inside out," i.e., the external surface is where the internal one
should be. By pressing the Alt and 1 keys together (Alt+1) you will be able to
"toggle" the symmetry of the wall about the base line.
Alignment
Should you find that the alignment of the wall is unsatisfactory, press the
Alt and 2 keys together (Alt+2). This "toggles" between three alignment
options:
1. First surface aligned with base line, the default.
2. Last surface aligned with base line.
3. Center line of wall aligned with base line.
NOTE:Walls must be created on the horizontal plane only.
