Cutting Arc Walls

You can cut square or rectangular openings into an arc wall by editing the elevation of the wall. See Editing the Profile of a Wall.

1. In either a 3D or elevation view, select an arc wall.
2. Click Modify | Walls tabModify Wall panelWall Opening.

   The Rectangles tool becomes active.

3. Sketch rectangular openings in the arc wall.
   
4. When finished, click Select panelModify.

As you sketch the openings, permanent dimensions appear. If the wall has a top constraint set to a level, dimensions appear from both the top and base constraints. If the wall has a top constraint that is explicit, dimensions appear from the base constraint only.
