I'm trying to add a simple cut to the end of a break line to indicate to the shop where the break line should be located. As you can see from the pic's, it's not always consistent. The issue seems to arise on all parts where a relief is present. As the code and pic's show, the bend line is projected onto the sketch, but sometimes the bend line start/end points are placed randomly out in space. Any ideas?
Thank you,
Eric...
