So I've turned off SoftPlan's tendency to automatically offset the small dimensions (Thanks for that tip, Bill).
I go to offset them myself, and when i try to add a pointer it freaks out about where it's attaching. Well, I don't really need the little arrow so I figure I'll just use an arc.
I put in an arc, and the small dimension snaps back onto the dimension line.
What's it trying to do? I can move the small dimension again, but it's kind of annoying. I guess I can draw the arrow first, but I end up having to tweak them in tight spots then. Is there a reason it would snap the dimension back when a line or arc is drawn nearby?
