For a customer i need to make some flat-patterns of step files. The most parts is not a problem, but these two are a pain in the ass!
One is a round cone (ø508 with 12mm height difference), and the other one is a chain box. With the convert to sheetmetal function i cannot get a proper flat pattern with the right reliefs. Both files you can find in the attachment. There is a bit hurry with these products!
