Vaulted, Cathedral & Pyramid Ceilings — RoomSketch3D

Add a vaulted ceiling in RoomSketch3D: drag a rectangle over the area — it snaps to your walls — pick a two-slope cathedral, a single-slope shed, or a four-sided pyramid, set the eave and ridge heights, and watch the room, its walls, and its hanging lights rise into the real sloped shape in 3D.
