Data tree question

hi all,
could anyone shed some light on this question:
I have a tree that is the product of and intersection between two families of 18 curves,
I would like to arrange the tree into 18 branches with 18 items into each one,
It doesn´t really mind that the branches include null elements,

Thanks in advancequestion.gh (14.5 KB)

You could use Trim TreeorShift Paths, BTW in the case items in each branch is 14.

thanks, HS_Kim

I am afraid that the problem is focused on how the curves intersect one to each other.
what I am really want is to transform all of these curves in polylines, then I have intersect them in order to get the points and in this way transform them.
I can see that the arrangement is not approptiate to do that,

any suggestion?

thanks again
