Hi Revit-community,
I've been trying to export a gbxml-file from a multi-apartment project to perform an energy analysis in an external program. I defined rooms to create the energy model and the overall model looks good. But for my staircase the ceiling opening does not produce "air" as the analytical surface but instead "interior", same as the ceilings. I defined a room for the opening on each floor (floor surface to next floor surface).
Does anybody know how to solve this issue?
