I have built a basement plan and now want to replicate the perimeter of the building on the ground floor and will do also on the 1st & 2nd floors. When I try to add a wall over an existing it highlights itself red as if it's forbidden for some reason. I have altered the elevation heights for the basement many times, including negative, positive and zero amounts, nothing seems to work. I have reviewed the users guides and the video tutorials. Need help please
