How can you tell what is joined, and how can I unjoin them?
If I move something, it's always telling me it can't keep members joined, and half the time when I want to stretch the end of a beam, it will drag another member along for the ride (or give me constraint errors)
If I right click and select joined elements, it's showing up a pile of members that should not be joined to (and aren't even very close to) the original member.
