We'd like a modern GUI update to Mac version of Archicad. For us this is pretty much the last hurdle stopping us from switching from Vectorworks.People say there are other priorities but you can say that about every version.The crazy thing is Revit's...
Is there a list of architects that use ArchiCAD in London?
I'm looking forward to reading people's experiences with TW2. Would I be correct to assume TW2 probably won't be available in the trial version of ArchiCAD 13?
Does Graphisoft or any ArchiCAD distributors hold conferences or road shows when they release a new version of ArchiCAD? If so, are there any in London, UK for v13?
What's the status of the Mac interface in v13? Has it been tidied up to be more Mac-like yet?
