I'm new to this software (Home Designer Suite 2017). I'm finishing the basement, and I'm not sure if I should draw interior walls along the perimeter inside the concrete foundation. The drawing shows a dotted line there and objects seem to snap to it, so I'm wondering if the stud wall is automatically added for me. What would experienced users recommend as the best way to represent a stud wall with drywall just inside the foundation wall?
