Commenting post 222: Yes, definitely the BIM world is a world where each of the player tries to pull all the customers in his nets. IFC, which is probably the best thing we have at the moment, is usually badly implemented, and in several cases (Revit for example) is supported only by external plugins. And gbXML seems to me a solution developed by the BIM providers to be unharmful to them (it is basically an export format, not made to carry all the information the model has, and certainly not made to import anything serious)

Although there is a lot of talk about that on the net, one of the things less implemented there is without a doubt interoperability, define sets of common standards, etc. I also think working with multiple applications and developing trustable workflows between them is a very important key. For me Blender (or sketchup, or any "fast" modeling app) is a fundamental part of the process (modeling in FreeCAD is slow and therefore can limit your spontaneity) but FreeCAD is another fundamental part (because of parametric modeling and complex data model). And there are other parts of the system too. The trick is to make all this works seamlessly and reliably together...
