yesterday
I'm using ArchiCAD 29 and I created a custom window (it's not a standard library window). When I place it in a wall, the wall opening appears in the right spot, but the window itself stays far away from the opening, displayed as a green ghost with a jagged outline. It never snaps into the wall.

When you create a custom window from slabs, set the slab reference plane to the bottom of the slab with the height at zero.
Everything above zero will be inside the wall.
