The most difficult part is maintaining the connection between the spheres. Using a transform on a cylinder is really messy because you need to scale, rotate, and translation the center of each cylinder for each animation frame.

Note that if you arrange the Transforms properly the "hub" sphere is always at the origin of the hierarchy that contains the 4 spheres and cylinders.
I do not want a line, I want a cylinder or extrusion—think Tinker Toys. I think what you are saying is there’s a good use case for Extrusion, or a different definition of Cylinder? That is all I’ve been asking for all along...
There may not be a ‘hub’ in the final product.
Thanks,
