It's a Revit problem. Autodesk is known for hating on OpenBIM, since it threateans their hegemony. I've never heard of anyone saying everything went smooth when dealing with Revit + IFC. It's still not certified for IFC 4 and 2x3 support is lacking at best. True however, you need people who know what they are doing :) Btw I'm glad we have options in the market. Same as with browsers, OS, etc. Mono cultures are hurting everyone.
