Resample a Grid of Points

I have a grid of points (that represent a surface), an I have ordered them using the Sort Points component. These points currently occur every 0.5 meters, but I want to essentially "resample" them to get a point every 2 meters. I tried using the Cull Pattern component, but, while it chooses a point every 6 points or so, it is only doing this in one direction.

This seems easy, but I can't seem to figure it out. Any tips would be appreciated. Thanks!

Is it a rectangular grid? or at least some pattern?

I would put every row in a separate branch and  then choose every 6th item

Hi Lily,

use Flip and Cull again.

Cheers, Peter

Peter,

Awesome, this works! I see your using Cull Pattern (instead of Cull Nth), that works much better.

Thanks for your help, much appreciated!
