A2Plus help. Engine animation with move tool

[dcapeletti]

Hi, I'm trying to model an engine with A2Plus. When I try to move the crankshaft to animate the mechanism, I can't get the movement to play properly. What I want is to move the crankshaft in a circular mode or a connecting rod, but when I do that some restrictions are broken.
What I need is to understand how to set the restrictions and how to make the engine move.

I've attached the file so you can try it out. Thanks
