ArchiCAD and Revit seeems to be the flavour of the month.
But i beg to differ. It only benefits developers who have their own inhouse architects, engineers, estimators and builders that can work collaboratively from start to finish or a partnering arrangement between the builder and architect where warm and fuzzing feelings are exchanged early in the piece.
Pretty 3d pictures can also be generated.
Otherwise its a waste of time and resources.
I'll stick to AutoCAD LT thanks.
