@brrbtr said: having some trouble getting doors and windows to properly cut into walls The bane of my newbie life! You watch the tutorial: the SU master Rectangles the opening, PushPulls it into the wall until it meets the far side. Voila! Perfection. You try it. Your Rectangle won't PushPull except in the wrong direction. Or it freezes up half way in. Why? The two sides of the wall aren't perfectly parallel. (Close isn't good enough.) Solution: use the oFFset tool to lay out your floor plan. Perfection without effort. There's other geometry in the way. Harmless-looking lines on the far side, for example. Also, use Camera/Standard Views/Top to look inside your wall.
