Creating a dummy room in roof opening area

Hello guys,

when you cut a roof with a dormer and try to place a room, the room boundaries are not correct. I tried to create a room with room seperation lines but no success.
There is already an article about that problem:

When I cut the roof with opening by area it works but it is not like dormer. The cut detail has to be a dormer.

My question: can we create a dummy room and ignore other references under roof with API?

Thank you!

You might have some luck in posting your question to the API forum Revit API Forum - Autodesk Community
