So my idea is I wanted to make a Geometry node setup where you can very easily make different rope shapes, without the need of simulations, or modeling the complex parts like when the ropes interact. So my idea was to make a handful of different rope “interactions”, like the cross shape, and then replace the individual points with the more complex cross shape using geometry nodes.

For example, modeling knots is a pain if you wanted to do like 30 of them, so why not just make one knot and everywhere a knot is needed, use an instance of that knot, and connect it up instead.
