I use both Solidworks and Cimatron. I find that Cimatron has the best design for a CAM package. The other guy here uses Mastercam X and I'm able to get toolpaths out quicker. I just wish the translators were free like every other CAM package. Find it kinda sad I have to use iges or step files. But other than that I think the guys at Cimatron are tweaking out all the bugs and adding alot of flexibility with it.
