Good afternoon everyone. I'm new to mastercam. I have been using for about eight months. I was just wondering if you can save a mastercam x5 file back to x4 without lossing all of the toolpaths. I used gibbscam for many years and you can do this very easy. My friend is a good programmer but he doesn't have maitanance and he has x4 and when I send him an x5 file when he opens the file it defaults all of the toolpaths and he can't see any of my settings.
