How to pull individual points from a scan?

Not necessarily min or max points, but more like a sample of 15 points from a 1500 point scan...

Maybe something like this?

I made a random scan of a radius. assign variables. I forgot to add variables for nominal values, but the basic concept is there.

why doesn't the nominal show up?
