Need a small help with getting specific point (lowest z value)

Hi, I'm currently working with a closed curve I have from intersection with an extruded circle and a curved surface. As a result I have a curve wich control points are several hunderds that define it, but I'm trying to pin out the point with the lowest Z value, sorting doesn't seem to work for me. Any suggestions?

you have to decompose the point into its x,y,z values and sort with the z values
use the second input for your points

You want to find the lowest control point or the height of the lowest point in the curve? If it's the second one, use a bounding box and a box corners component.

it was the lowest point in the curve. Will look into this in the morning, thanks for the input.
