Knowledge Fusion :- A Beginner

[Pondering]

I am trying to get my head around knowledge fusion as a language (trying to stop myself from using GRIP)

I starting with something simple: - create equally spaced points along a spline.

I can select the spline, I can even create points on it, but not along it, they are all on top of each other!

I can't seem to get the hang of the child and nth rule.

Does some kind person have an idiot’s guide or an example?

Cheers in advance,

P.....
