Gross Area Boundary


#1

Does anyone know how Revit determines that a wall is an exterior wall when creating an area plan? From a few tests in Revit I’m assuming it has something to do with walls that have been completely enclosed. Would it be possible to pull this information from Revit to create Gross Area Boundaries in Dynamo?

Here’s a related post about getting all of the wall lines on a level. Thanks in advance.
