When you do this, the program stores the position of the trim relative to the Wall base. So if you lower your Wall the trim will also go lower.<BR /> You can do one of two things:<BR /> 1. Undo the Trim and then Trim the Wall again with the Roof. In this case you will have to redo it if you place the Wall to another location vertically.<BR /> 2. Use SEO, which creates an associative relationship between the Wall and the Roof that cuts it. In that case when the Wall is relocated vertically, the cut will update on the new location of the Wall ans Roof relative to each other.
