I have not worked with chief architect or ArchiCAD as of yet. I am working with AutoDESK architecture 2008 at the moment. How different or similar are they?
The local architect in town is using archiCAD. It is very powerful and not limited to 15 floors like I was told that chief architect was (don't know if that is true).
I also work with AutoCAD, and Inventor (both 2008). I am wanting to get ahold of solidworks, but don't have access to it through work yet.
