I've got a part that I'm finishing up the programming that our previous programmer had been working on. It's a housing that gets cast and later machined. but for the cast stage our drawing has a bunch of surface profile callouts. I noticed the scans that he had were set to master. My understanding is that if you have a reference part that's fine, but to my knowledge we don't, just the CAD model. Would it be advantageous to change this?
