Hello, I´m using ADT and have the following problem: I have a wall that has two kind of wall styles on top of each other (lower concrete and upper lighter structure). When I insert a window or a door into the wall it "sinks" only into the other wall style, the other is not edited. The result is that the window or the door doesn´t show in the other wall style (in 3D). Is there a way to do this so that adding a door will affect on both wall styles? Pekka ps. English is not my native language in case the question is difficult to understand...
