MARCV                                                  Menu: Non-menu command
=============================================================================
Determines whether multi-layer wall arcs will display vertices or not.

 1. (Y/N) vertices on? <y>

Description:

This command determines whether multi-layer wall arcs subsequently
projected into the third dimension will display the vertices at the
junction of each arc segment.

The command also determines the display after using the following commands:

\mw3d
\uwasg
\updoz

In order to change the display for existing arcs, remove the 3D model
of the walls using \mw2d. Set this command to the required setting and then
recreate the 3D model of the walls using \mw3d.

NOTE:You should use this command immediately prior to giving height to the
     walls globally. If you use the \wal3d command on an individual wall you
     will be asked whether you wish to display the vertices for that wall.
     All subsequent uses of \mw3d will use this setting unless you reset the
     display of vertices using the \marcv command.
