Hi All,

I’m new to the forum, although I’ve been using it a lot to learn how to use grasshopper, I’m hoping I’ve posted in the right section.

This time unfortunately I couldn’t find an answer to the problem I’m trying to solve, hopefully someone can help me.

I have a series of “main” curves defined by several segments (curves).

These are not drawn in a specific order.

I’m trying to:

- reorder the curves so that these follow the main curves, starting from the bottom to the top (ordering based on the Z direction could also work but not ideal)
- group the curves into sub-groups, so that I could select say 30-40-50…100% of each curve starting from the bottom.

I’m attaching some screenshots which hopefully help understanding what I’m trying to achieve.

I’ve tried to join the curves together and shatter them but with no luck.

I’m not sure if there’s a grasshopper component that does this.

Any help would be much appreciated!
