Hello, fairly new to Mastercam. Using X5, we have a left and right (opposite) part. Anyways, some guy wrote a program for the right part (solids), and all the coordinates are fine, posted fine, no problems. Then he mirrored, or flipped the part, to make the left part. However now, my x and y (tool, graphics) axis are both going negative. When I verify the part, it looks fine, however when I post it, and run it, it seems everything is shifted to the left. I'm sure there is an easy fix, I just don't know it. I think it has something to do with the WCS, and like I said I am new, and actually was never taught on solids, but am winging it, until now. Any sugestions please?
