Add a true ceiling and create a false ceiling with offset

Add a true ceiling with the ceiling tool, then build a false ceiling by drawing a rectangle or offsetting a copy for a peripheral one.

2. If the ceiling sits too low, check the wall height by clicking the wall thickness (not the surface) and set the ceiling height to match.

3. For a false ceiling, select the ceiling, choose Create False Ceiling, then Add Extrude Shape, and draw a rectangle corner-to-corner with the Rectangle tool; Apply adds it.

4. For a peripheral false ceiling, use the offset command with copy to retain the original rectangle.
