Hi, I'm migrating from “3d Max” to “Houdini”.

I have created this asset(image), where the chairs are copied using the copy node, and bunch of manipulations to a curve's points.
I want the chairs to be able to dynamically rotate around their shaft.

I have managed to do this for a single chair, using the “RBD Hinge”.
but I can't seem to figure out how to do this for the copies of the chair.
I want each chair to be able to rotate separately from the others (if I throw a sphere at them for example).

In the documentation reference I have found this node(DOP) called “copy data” but I'm not sure this is what I need, and if so, how to use it.

*.hipnc file is attached.

Any suggestions?
Thanks
Noam
