I am working on a remodel that has an existing cathedral ceiling with different height side walls. One end of the cathedral is an exterior wall and the other end is a wall that we are going to take out and put a beam in its place because the ceiling height on the opposite side is 8'-0". I am new to Chief Architect and am having trouble with getting the 3D show the cathedral ceiling correctly. I separated the room with a room divider so that I could show the cathedral. We are going to use beams and posts for supporting the load bearing walls that we are removing. I am attaching pictures below of the existing space and my model. Does anyone have any suggestions?
