Please…

Today I have spend hours trying to make this work (I finally did). But it is still baffling that I am required to use 9 components when I should be using 1 for such a simple task. Maybe I am just not good at data managing, or maybe GH isn’t good at it…I collapsed the problem into this simple example.

I have a grid of points, organized in horizontal branches, and I want the tree to be organized in vertical branches, do some operations, **and then be able to go back to the horizontal branches structure.**

I first tried a geometrical solution, using point in curve. Going back to the previous structure required a different approach using` Create Set`

and `Member Index.`

This approach proved its limits when the points are superimposed over one another.

I then tried a data management solution, looking through old threads on the forum. At first it did not work, and I was stunned for a long time, because it should have worked… but of course, `Insert ItemS`

**(mind the “s”)** does not work with multiple indices, or at least not as one would expect. I revisited an old thread of mine where I noted this, but the solutions provided there did not work with this case.

Hopefully `Sort List`

made it work.
