When exporting gbXML in order to get room volume information you must goto
settings, room and area settings, and check Compute room volumes.

We are trying to export to IES from Revit Systems. When we do we lose room
objects and openings. Is there a procedure or documentation for performing
the gbXML export that would help? Are these known issues or are other users
more successful?
