Of late, I see all bend lines, all the time. In parts, in assemblies (but not drawings) - they're everywhere! I've tried ticking Hide All Types under View, but that does not help. I've looked in the Sheet Metal options, but nothing relevant is there. Sketches are not shown (not that it matters).
How can I NOT see bend lines at all times?
Are you sure those are bend lines and not tangent lines?
