Having the same issue here with room calculate constructed a 16x8 room only figures the ceiling no wall drywall. it will get the door window trim even hinges and locks but no wall drywall or paint 4 - 4x8 sheets that is simple enough to see it is just the ceiling. there response to me was. I can do all floors or area and subtract what I don't need. in 3500 sqft as built all floors doesn't make cense at all and if the room was surrounded by 3 walls I would have to subtract. hope there is a fix for that soon.
