I have this rows of points called "start' and "end". From the "start" group I want to instance a Curve Line whose start point uses index 1 and another Curve Line who uses index 2 and so on with the other Curve Line that will be instanced on this group. After this Curve Lines are instanced on the "start" group, I want its End points to be located on the points of the "end" group.

My problem in here is I can do that but with only one Curve Line. I want to make sure I can create limitless amount of Curve Lines which start and end points are located to this limitless amount of "start" and "end" points.

  • $\begingroup$ That's OK, but the people working on answering the questions here are trying to keep the information compact. Basically, this question is just a variation of your original problem, but technically identical. If the questions are tweaked so long that a really clear answer can be given, it will increase the usefulness for visitors who have similar problems. Maybe it would be good if you try to specify your question again, so that we can really help you to answer it specifically. $\endgroup$

It depends a bit on how it's most convenient for you to sort the indexing, I think.. but here's an example, assuming your groups of start and end points are independently indexed 0-N..

enter image description here

  • The curves are instanced on the start points, and their instance-indices captured
  • After being Realized, the Endpoint Selection of the curves is moved to the 'end' group of points, keyed by the captured instance-index.
