Hi all.

I have random rocated lines.

I have to sort these along the curve and choose every '5n’th lines, like 0, 5th, 10th…

Cause I couldn’t find the way to sort curves along curve, I was going to make intersecting points of the curve and lines >> use ‘sort (point) along curve’ >> pick every 5Nth points using ‘member index’ >> pick lines that intersecting with the 5Nth points.

But the problem is I cannot use MEMBER INDEX for the point list.

What I have is this kind ▼

and I don’t know how to use MEMBER INDEX for this kind of list.

I think I can use it only for this kind of list ▼ , if the items are 1,2,3…

- How can I change the list type (1) to (2)?
- Is there anyother better way to solve this problem?

Thank you so much!
