Description

This command updates the height of an existing multi-layer wall or arc.

Specify the new height of the wall.  The currently set values will be
displayed.  Specify the height at each extremity of the wall.  If the two
values are dissimilar the head of the wall will be sloping except in wall arcs
which will assume the last value to be equal to the first.  Specify if you
wish to change an individual wall or all walls.  If you select to change a
single wall, indicate the wall whose height is to be changed.  You are
prompted to indicate another wall to update until you enter another command.

If the wall or arc is already displayed in 3D, it will immediately be amended.
If it is still in 2D, its database will be updated and the new height will be
seen when the wall is given height.
