Hello Jared, I am E. R. Robbins. I am presently attempting to use CA for planning a major remodel. The first floor is on a slab and we want to install a bathroom. Ceiling height is 10', so we can raise the floor level where we want the bathroom by 2' in order to allow plumbing inside and above the slab. Do you know of a way to make this happen? My efforts have resulted in all sorts of things happening with foundation, framing and roof levels.
