I just spent half an hour carefully creating a diagram. Then repositioned one line to which many other lines were attached, and everything went wonky. Undo did not restore my original. I have a mess now.
I was right then and there ready to ditch Omnigraffle.
Searching online I found a way to disable magnets for newly created lines, but how do I disable them for my current diagram so that I can attempt to correct it?
I’m using Omnigraffle 7.7.1 for Mac.
