When I add a new First Floor of 1-1/2" this sets my original floor to the Second Floor. The problem is I didn't insulate the floor of the attached garage or the porches. On the Layout for my floor plan, it wouldn't show the garage and porches on the same Layout as the "actual" first floor because the actual first floor is now the second floor. If HD Pro isn't able to do detail this insulated floor I'm working on that's fine. I've been extremely impressed with the program and understand some of the non-standard details are probably better managed in the full version of Chief Architect.
