I have a series of polylines, deconstructed to their control points. I wish to find the point with the lowest X and Y value, and display text there, in this care a text showing the area for each polyline.

I imagine sorting in two rounds makes sense. The highlighted point has first lowest Y point, then from remaining two points with identical Y points, the lowest X point.

Thank you! It seems to work, but what I don’t understand is that it seems to remember if the polyline was flipped/mirrored and refers to the point in relation to that transformation, which is odd. So bottom left becomes top left if I have mirrored that polyline before. I’m using a geometry pipeline if that makes a difference.

So you sorted the list of points taken from the polyline, took a subset of the top two points and sorted the X value, retrieving the top value, right? Could you explain the This & That gate part?
