I have been working in Chief for about 3 months. When I am working with the exterior walls - specifically changing the wall types - I am continually having to adjust them to keep the interior measurement I need. As you can see in the added images, when I change the wall type, it shifts the wall by 1.5625 inches into the room.
1. Why does the change in wall type change the location of the wall and change the interior dimension?
2. Is there a way to prevent this from happening?
