Modify Wall Reference Line

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
The Modify Wall Reference Line command brings up the following dialog box:
Edit Reference Line Location: Check this box, then use the controls to move the reference line of the selected Walls without changing the Walls’ position on the Floor Plan.
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.)
