Sets or resets the height attributes for subsequently created multi-layer
walls of the current type.
(A nested command.)

        1. (NUM) height of wall (z1,z2) <n n>

Description:
This command sets or resets the height attributes for the current multi-layer
wall type. The two heights (z1, z2) are heights above the start and end points
respectively. Any wall subsequently created will be assigned these heights.
Multi-layer walls may have a constant height, or you may vary their height
from the start to the end points by assigning different values to z1 and z2.
