Help using dials for an interactive wrench

Thanks for the reply, Steve.  I actually had found that one in my search.  I worked out how to make a dial work for the ratchet, but the problem I'm facing is the "changeover" from one rotation point to a different one, ideally without the user having to do anything other than the click and drag they're doing.

What I want to do is make a dial of a group (the whole ratchet), and then make a dial of another group within that group (the handle),set a trigger that says when dial A reaches X degrees, "turn on" dial B.  But you can't "nest" dials, and I don't know if there's any way to accomplish this goal of letting the user interact with it to get the desired result.
