Hi, I'm attempting to create curves from hair cards (polygons). I was able to do this for a single card, but I'd like to be able to procedurally achieve the same result with all cards.

How can I end up with only the side edges of a polygon remaining? At this time I had to manually delete the undesired edges then use a fuse node to end up with a single curve.

If there's a better way to generate curves from polygons, please let me know. Any input is appreciated, thank you.
