Problem with Room.Boudaries

Hello everybody !
I have a big problem with the node “Room.Boundary”.
I have a room delimited by 6 walls but the node gives me 9 walls …
I don’t understand why.
Does anybody have an idea ? It’s urgent !Capture

Hello @hauvillec …thats the way room-spaces works in revit…you could try to croup them or join them

To clarify, it’s returning 6 unique walls 9 times. Bounding lines are tied to bounding elements but are individual curve instances. This just means that you have something “interrupting” a bounding element, causing multiple curves to be created.

If you click through the outputs of curve and compare them to the element list you’ll see exactly what walls are getting interrupted and where.
