Total wall area in room

I want total area of room without door and windows…

I stared with get room boundary and with ray bounce from corner point of boundary check the room height to bottom of next floor.

then I extrude boundary to this maximum point for create surface. Now I have wall area of each room but door and windows …
I am looking for boolean function my surface wall and door and windows…

Or is there another way?

Rhythm package: room.doors and (or sth like this). Then you can extract areas of all doors/windows in room and do some calculations.

Do you have a subscription account at Autodesk? If so you’ll probably want to try the Roombook Areabook Buildingbook addin for this kind of operations.
