All I want to do is to create a sloped ceiling without worrying about roof etc. I was able to do this is another program by simply clicking on a wall and making a different height. I do mostly interiors, don't have to worry about the exterior for presentation of a room or closet area - or attic. Is there a simple way of doing that? I can be emailed at elainesdesign17@outlook.com - this is driving me crazy:):)
