So, every rigid body have a reference point around which rotation is free (RP1-RP5).
Free rotation of the rigid bodies around their own axes.
But, all rigid bodies rotate around the reference point RP6.
I have attached an article to show you why I need two reference points.

I want to assign two reference points to a rigid body in Abaqus.
To assign the first point I used the constraint Rigid body.
What constrain can I use for the second point?
I try with coupling constraint, but I think it takes too long simulation.
Sorry for my enghish!
