Projecting Door Openings on Surfaces in 2D Using Bounding Boxes in Dynamo

Geometry

Hi everyone! I have created a topologic cell model from room boundaries in Revit. Then, I converted these room boundaries into a single surface without any overlaps. Following this, I generated bounding box cuboids around the doors in the model. My goal is to project door openings as curves onto the intersecting surfaces—essentially projecting the door bounding box boundaries in 2D onto the surface.

I followed these steps but encountered difficulties at a certain point. I would appreciate any advice on how to proceed further.

Can you show the whole graph so we can see where you’re projecting the door geometry onto the room geometry? What issues are you running into? Are you getting any warnings? We need more information.
