In Europe (EU) when it comes to government, you are not allowed to say "You should use Revit or ArchiCad". There are some that does it, but if an office with other software are will make an offer, then they could appeal against the contract and probably will win in a court and then they will have to restart the process from the beginning.
I'm now working on a big (in swedish terms) housebuilding company and we are working in ArchiCad (architectural and construction drawings) and DDS Housepartner (production drawings & cutfiles for our internal precast production). And propably in a near future, we are going over to BIM in our bigger projects, and then our consultant are needed to deliver in formats that ArchiCad could read!
We have no plans to work with any kind of Autodesk products (or other softwares) in our firm or other, we get all we needed from ArchiCad, ofcause there are some functionality that could be alot better but what software doens't have bugs or bad working functions?
