Hi all, Someone just asked this, and I thought it would be useful to share the answer with everyone: why don't Booleans work on "rooms" created with the Room Builder tool (but they work on regular Walls)? Answer: Room Builder creates a Group of Wall objects. Since Booleans only work on individual objects, simply Ungroup the "room" you built (this will result in individual Wall objects), and Boolean away! Hth, Dany
