Subtracting one list of points from another

Hi everyone!

I'm started using GH this week and I'm trying to use it to describe a wooden frame. Right now I have two lists of points and I'm trying to subtract one list from the other, essentially creating a list containing only the points that don't appear in both lists.

Apologies for what is probably quite a straightforward procedure but I've been stuck for a while now!

Thanks in advance, Ollie

Just to show everyone what it's for, here's an image!

I've set up a screen that has vertical slats at random intervals (set within a domain of approx 940-1560mm) and regular vertical support elements. I want to cull the vertical slats that are too close to the vertical supports. The worksheet has become something of a monstrosity due to my lack of experience with data management, any tips on how I might have better approached this would be much appreciated, ta.
