Point contained in linked room

Hi there all

So I am trying to attatch roomnumbers to all of my windows, so that the window tells which room it belongs to. But of course all of my rooms are in a linked file and not the facade model im working on.

But because windows always outside rooms, they dont show within bounding boxes or other room nodes and especially not linked rooms. Therefore I have tried attaching points to the windows, that the room could pick up. But It does not…? Any suggestions?

What about someting like this? :slight_smile:
