Yeah that would work, but I was thinking even with the idea I gave there are too many steps and typing involved, something with less steps, like if you had that 'define variable' or 'reference' button beside each input box (x, y, z) as a small button and once pressed you can pick that edge mentioned previously and the length value would be placed in the input box.
But then as you implied, how many times would we use it, just thinking out loud.

Keep up the good work
