How to connect two bones to one knob (scissors hand)?

Hi everyone!

I have a problem connecting robotic hand with scissors using bone tool. Everything works just fine but I cant attach bottom blade of the scissors. I want it to be connected to the middle bone just as the top one and that it will move with the whole hand as I would drag it.

I tried to find the solution and I couldnt find any. Maybe you can help me? Do you have any advice how to do it? Or maybe some tutorial that I couldnt reach? Thank you in advance!

It seems there can be only one pivot point per symbol. If you made a circle at the end of the arm, that could be linked to the elbow, and it could also be linked to the two blades. That might get you want you want.

Connecting the bone to a shape usually makes the shape be a symbol, but in the case where you're connect from the same location to another shape, it seems to not work. If you make the three parts be symbols before you connect them as bones, the connecting works ok.

But, if they are all on top of each other it can get confusing, and you end up connecting the bone from the wrong one. So, make the three parts away from each other a little bit, make them be symbols, and then use the bone tool to connect the two blades to the wrist joint.

Once you have done that you can Command-drag (control-drag on Windows I guess) on each blade symbol with the Selection tool, to move the two blades into place.

All joints are already symbols, to be exact, movie clips. Now I have something like this:

1. When I drag the line the whole arm moves around (also scissors)
2. When I drag scissors they are moving aroud the "elbow knob"

What I need them to do is that they would stuck on its place and be connected to the last circle instead of the middle one. I thought maybe pin would help but it just pinned the whole thing to the backround.
