Here's the scenario, I get a solid works part from a customer and I do my normal routing of making the bend radius reflect the punches we have and change the k factor according to our brakes. It's a no brainier 95% of the time but every now and then when I change ting it alters the dimensions of the part, enough to be out of tolerance. This is the first time I've experienced this in SW2012 but I must note that the part was drawn in a previous version. I have seen this in 2011 though. Any thoughts as to why this would happen?
FYI the part was originally created as a sheet metal part, not an extruded base converted to SM.
