I know you didn't ask me specifically

but we run gibbscam 2010 with volumill and 2.5D milling at work.
Allows us to use solidworks models and because of volumill, it actually provides powerful, time efficient roughing cycles. Youtube it, volumill kicks ass when you get it working lol
But I don't use it for anything else, the regular fast programmed roughing cycles generated by gibbscam and pretty well all other cam software out there are that of a level 1 machinist.
I still program 99% of our parts in G-code right on the machine, it's not necessarily as fast as cam for programming time, but significantly more efficient in cut, easier on the tools, easier on the machine, and way easier to modify/tweak.
