well, so far, I've only used picasoft and dental softworks, as they were bundled with the mills we bought. we were told that fits were superior using hyperdent, and that these cams were a waste of time, and their result seems to confirm it. now, my boss is dead set on getting hyperdent. unfortunately, they don't work with most of our mills but future ones will be. so, is there a big difference between typical cam software and sum3d/hyperdent in milling accuracy? I'm guessing sum3d and hyperdent are about equal in function?
