Also is there a way for when I move the interior walls that it doesn't change the exterior walls?

I have tried several other packages and have had the same problem and am curious if I would with HDP? I flip houses, the house is already built and the sheetrock is up and finished, so I go in and measure the rooms with have inside to inside dimensions, none of the other package let you layout a room based on the inside to inside measurements. Is it possible with HDP? If so what do you have to change for it to function in this manner? Thx
