How can I find faulty Room boundary?

[m.knutsson]

Hi,
I'm working with en IFC-model and Revit can't find all Room boundaries and I'd like to see exactly where the problems are in the model so that we can get them fixed. I don't know how to show this!?

We've got a Coordination View set up in our Revit template that has only Room Bounding categories turned on (Walls, Curtain Walls Columns, etc)
Also turn on all the sub-categories under Room as well as Room Separation Lines (under the Lines Category). We set the RS Lines to Line Weight 20 and Magenta so they pop out.
The darker blue areas indicate where there are overlapping Rooms
To diagnose, you can start drawing extra RS Lines through the middle of those areas until you've isolated a Room by itself.

Then, you'll need to figure out why it's not Bound
