OK, I am new to Chief Architect, and I am sure there is a simple way to edit this, but I am lost in finding it. I am starting a new remodel project by building the existing plan. The exisitng structure has 84" high exterior walls, 4/12 roof slope with cathedral ceilings, however, the top plate elevation is locked at 109 1/8" and I cannot find how to change this to the required 84". I have the ceiling heights set to 84" and the default 1st floor set to 84", but the sections and elevations are still showing the higher plate height. Any help appreciated.
