Grouping curves that have different z coordinations into branches

Hello everyone, first of all I would say I have little experience on Grasshopper.

I’m trying to sorting curves that have the same Z coordination (basically sorting curves that are on the same level into branches). I’ve tried to extract Z coordination data then I evaluated them for dispatching the data, but it seems like the data out put was correct only the first branch. Does anyone has suggestions sorting these curves?

Thank you.

Hi @kian.jansuwan,

welcome to this forum.

Often it is convenient to post the geometry you are working on.

To branch your data according the z value there are several possibilites, here are 3: (11.0 KB)

Hi Baris,

Thank you for your helps, the picture attached showed the curves that I want to group them by their Z coordination, anyway I uploaded the picture again here.

The image is useless to Grasshopper.

3. Attach minimal versions of all the relevant files

P.S. Member Index can be extremely useful for this problem.

If you dont reply directly to an answer you have to tag the person with an @ , otherwise he will not get noticed about your reply.

If you cant understand the generic examples provided it is even more suggested to post the actual geometry.
