Animation for 2 circle rotation

[Anonymous]

Hi guys!

I am trying to animation a smaller circle tangent to a bigger circle and the smaller circle rotate freely itself following the path of bigger circle and always a point tangle to bigger circle.

Thanks.

you can use two joints. One main that is in the middle of the outer circle, then another child joint that is skinned to the inner circle. Make both circle in the Center, then skin and move the child joint into place. Then you can rotate the main joint to rotate around the outer circle, and rotate the inner joint for any extra rotation/movement etc.

I found easy to do it, just draw a small circle in the center of big circle and set its radius equal to distance of center different of the two circle. Then create a locator on the on smaller circle. Parent locator to smaller circle and then use attach to motion path.
