You can pin it to your PV control by using two distanceDim nodes: one from the start joint of the IK chain (upArm) to the PV control, and the second from the Pv control to the joint at the end of the chain (wrist). Then you just have to blend the distanceDimShape.distance values into the Uparm and Elbow tx with your elbowPin (or whatever it's called) attribute.

It's key that the three joints in your IK chain lie on x, y, or z axis plane. If they don't, the elbow will drift as you move around the PV.

Hope that helps.

Hi Crumbly,

Thanks for your hint, I got the blending idea. All is working fine.

Rgds,
