[#1]

I downloaded this toilet toilet stall accessible and need the wall/door to appear black when cut in plan view, how do adjust this in the family type?

[#2]

One possible solution is this:

• Family 1 is a detail component, with a filled region with solid black.fill.
• Family 2 is the model family that you show in your attachment.
• Load family 1 into family 2. Place and constrain family 1 as required.
