I'm trying to set up a notch for TDC. the turn over is 2" but it needs 2 5/8" notch to go through the roll former. In the connector dialog the seam cut back doesn't change anything. I can change the turnover to 2 5/8 but the part will be 5/8 too long. same as with other connectors like 1" Tap you have to cut the lock seam back further to allow clearance to bend it or form it.
