Hello, please let me know if I’m missing something that was already stated!
The popViewer is fine for looking at a POP to see point indices and normals, but the display options dialog from the POP itself doesn’t seem to do anything when turning on any of the Guides & Markers. I noticed a circle pop had 12 segments, and 13 points, but 14 vertices. So I wasn’t able to see where the 14th vertex lies on the POP itself using the regular display options.
