Sort lists by proximity

[BIMadmin]

Hi Nick,
I think I got what I needed from this post:

Closest point for given point sorting loop

Hi dynamo users. I stucked with idea of loop that can sort the points by distance but not from just one point: ->Starting with starting point and point collection,-> then find closest point to the starting then take the found one and repeat the search of closest one. Then sort it in found order. [image] I tried with loop while node after I created custom node that giving the closest point and rest of collection. Ty for help!.

I need to copy z coordinates from a list to another list based on the shortest distance.
