This may be a dumb question but it's driving me bananas! Is there some way to disable the feature self-snapping option when editing? For example, I'm trying to snap the endpoint of line to another line (moving it a very short distance) and the endpoint snaps to itself rather than the edge of the other line unless I zoom in to a ridiculous scale like 1:20. Why is snapping to itself even an option? Is this a snapping tolerance issue?
