‘Vector | Points | Cull Duplicates’, AKA CullPt
Of course, it’s not quite that simple when the points are in separate branches… Which is why posting your GH code/geometry is so important.
P.S. You’ll need to flatten your list of points to cull the duplicates, then use ‘Closest Point’ on the original tree to find the closest point from the culled list.
