I am looking for best and seamless solution to turn door and window family to non-room boundary opening so the room family takes into account sills and small setback area around those elements and includes it in total room area.
I don't want to use wall openings, non-wall based families or manually place room separation lines to overcome this issue. I have found out that if the room separation line is placed on a top of the wall revit will correct room boundary so it coveres this small area but I am currently working on some large residential projects so we are talking about thousands of doors and windows to be manually modified one by one.
It looks like the ideal solution would be to embed the room separation line within the window or door family so its distance from the internal face of the wall can controlled i.e. by using parameter. I guess it is not possible to do it traditional way but would this be possible to acheive for example by using some clever API?
