[Closed] Changing referential of animation

Greetings gentlemen,

I have an animation that could be described as follows :

A moves while B is still. (B is the referential)

Now I’d like to have the relative animation of this, but with A as referential (B moves while A is still) like a car turning around its wheel

Knowing that, after some time B has its own animation, is there a way to change the referential of this animation ?
