When you define a wall, you can use the command line to specify parameters:
Pick the beginning point
Pick next point [Side / Offset]
where:
Side = the location of the definition axis of a wall (upper, lower, central)
Offset = the distance from the lower or upper level of a wall
Note: When you define an element on the central axis, side and offset are not supported.
