Is this the same problem I’m talking to you about over on this thread?

How to modify the dimension of cuboid which is created by bounding boxes

Don’t use the wall.orientation node, just use the families rotation given it is in the wall, then use that to rotate the bounding box. You will need to find the point halfway up the height of the box, and halfway away from the wall to place the box at that point, then rotate around that point. I’ve built it for you, as it looks like you’re not quite sure which nodes to be using here. From here the rest is mathematics based on the door parameters I think. bounding boxes.dyn (34.0 KB) [doors]

I’d suggest just focusing on one solution ideally…
