No wonder all the smaller AEC software firms out there are pushing OpenBIM very hard. If you think you need to convert an Archicad .pln into a Revit .rvt you're doing it wrong and essentially playing into the hands of Autodesk. We really need to stop with all that siloing going on. OpenBIM with IFC and BCF are the only way of going forward. Revit is a mediocre product in all categories, but that's the thing: People are using Revit since it somehow can do all the stuff a bit. Architects love Archicad because it's a software tailored to their needs and far superior to Revit in that domain, but if you're a consultant doing e.g. MEP work you will be probably not so happy. You still won't be while using Revit, but since "everybody" is using it at least you won't have to deal with OpenBIM and correct file workflows. Source: I'm an architect myself.

Yeah, IFC is the format I had experience with trying to coordinate between ArchiCAD and Revit. There's probably a better way to do it than the way we did it at least at first, because initially Revit imports the IFC with everything as a generic "object" family instead of windows, doors, ceilings, etc. which make it impossible to configure views to show the correct things. There are probably settings in ArchiCAD that fix this when exporting, but it takes experienced people on both sides. In the context of design projects that don't always have the most realistic schedule, it's just one additional hurdle to deal with that isn't there if everyone is using Revit.

  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.
