I am working in Home Designer Pro and have created the exterior walls in my design. When I select and create "interior walls" from my tools options, the wall draws and appears as an interior wall, but if I open up the wall specification box, it is an exterior wall. Same for doors that I drop into these walls, they are all exterior. I would appreciate any help or advise on what I may have done incorrectly. Thank you,
