Attached please find an IFC file with two curved walls and a door in each wall (the corresponding Revit Architecture 2012 file is too big to attach here even though it only has four objects). It looks like one of the openings doesn't line up with one of the doors in the exported IFC file. I've looked at the IFC file in Tekla Structures, BIMSight, and have verified the errant opening position programmatically.
thanks, Chuck
