Closest points from sets of curves

I hope this image is self-explanatory. I can't Flatten because I need to keep points in their indexes so I can use these indexes later on. But I am having a hard time making Crv CP search for all of the curve in each main branch for each point. Help?

Hello,

Thank you for the reply, but still not resolved. The unflatten command is indeed good in what comes to mantain data structure. The problem is that CrvCP didn't work as expected. I attach an image and a .gh . For each bright blue point, there should be a closest dark blue point on a curve of the same branch index - that is, in an immediately lower z-value.

I've made some improvements over the last file, but still doesn't work. (the improvement are regarding culling the top most curves and bottom most points)

Hello,

I think you want to find the closest point of curves in below level from points of current level..

I attach a solution.. but I recommend that you need to exclude points in bottom level of center area..

I used Tree8 components for using sort within related distances..

Abbondio, that works perfectly, but doesn't give me "Curve Closest Point", which I need because of the t parameter so that I can Shatter them afterwards.
