That corner on the far left looks like it’s not being culled but is, because it’s very close to another point. (you also happen to have a number of duplicate points.)
Hi Ethan, thank you, this is a great way of doing it! Can you suggest any other way of doing this without using the curve evaluation angle? The angle doesn’t always work for me, as sometimes on other curves I get corner points showing up as 0 degrees.
Another idea using the Cull All option of Cull Duplicates…
You can input some tolerance if your goal is to remove those two very close points on the left.
