Geometry Intersects Gives Empty Lists (3). Why? (In 47, out 44)

including half of the Wall?

No, the whole wall which seperates the rooms.

Thats why i want to create ONE solid from all the rooms. All the walls i need would be in that solid.
This is whis give my Curves an offset. My (Room) Solids will overlap so i can create ONE big Solid i
can use to create the new boundary.

Basicly this, but because the Room.FinishBoundary node doesn’t allways get all the boundaries (Curves) / seems not to allways work i tried it with Solids.

Edit
This is working for me again except for this still

Hmmz
