Filtering points with Z value

I have list of points (like 100 or something like that) and I want to filter all the the points which have 0 as Z value.

I found an old thread about the same issue ( ), but unfortunately I can’t figure out what components they are using in the solution.

Could somebody tell the names of these components so I can find them in Grasshopper? Thank you.

here’s a recent example Sort the edges of a surface by z coordinate
