Anemone – Closest Point from Curve to Curve

Grasshopper
, , ,

I need a proper Anemone pattern for “walk through a list of curves while passing a changing point forward”, using Repeat mode.

I have a list of 51 vertical curves, evenly spaced at 3 mm in one direction (already ordered).
I also have one point on the first curve.

My goal is to create a sequential closest-point propagation:

  • Take the point on curve 0

  • Find the closest point on curve 1

  • Use that new point to find the closest point on curve 2

  • Repeat this step-by-step until the last curve

I appreciate any support!

Done. Also noticed a duplicated Curve and fixed that.

Your curves were not sorted.

Thank you. Also i had to set the end loop on record mode. Otherwise it always gave me one point as output.

Heres everything cleaned up, if anyone else got the same problem:
