When adjusting pSquared decimals, to avoid tiny closure loops when dropping below closed curve tolerance, it seems to be better to close a gap, rather than spread crossed curve ends. Two mirrored curves, unjoined may be better, which would require slight modification to the script. Maybe an unjoined checkbox?

Made a "pringle" and half Sphere solid with loft.

ps, Keyshot has Windows explorer thumbnails of .bip files. Didn't someone request .3dm thumbnails?
