Problem with Skeleton
 

I have made a Skeleton with three bones and after, with IK Handle Tool join the two end bones. But I want rotate them supporting the distance between(among) both last bones.

thank you...

explain what you mean more clearly, the image you attached doesnt go any way to explaining what result you want.

I think he meant he want to rotate everything around that green line between the first and the last joint ***

i understand that ur problem its about bone rotate so bone not in the same line u have to use just move transport when ur setup ur bone

um, pole vector constraint?
