Cutting Openings in Floors, Roofs, and Ceilings

Use this procedure to cut an opening in a roof, floor, or ceiling (for example, to accommodate a chimney). You can cut openings in the faces of these elements, or you can select the entire element to make a vertical cut.

1. Click By Face or Vertical.

   Where is it?

   • Architecture tabOpening panel
   • Structure tabOpening panel

   Use the By Face option when you want the opening to be perpendicular to the selected face. Use the Vertical option when you want the opening to be perpendicular to a level.

2. If you chose By Face, select a face in the floor, ceiling, or roof. If you chose Vertical, select the entire element.
