Use the commands of the Reference Line and Plane hierarchical menu to modify the Reference Line position and the direction of selected Walls. By default, this menu is at: Edit > Reference Line and Plane.
This command moves the reference line without changing the Walls’ position on the Floor Plan
Doors and Windows remain unchanged (unless you also check the following box):
Note: Modifying the reference line location here has no effect on Complex Profile Walls.
Edit Offset: Check this box, then enter an offset distance (if any) of the reference line from its defined location. A positive number moves the reference line toward the center of the Wall core; a negative number moves it away. (The Wall itself does not move.)
Offset is not available if the reference line is at the Center or Core Center.
