hmm. I hesitate to add yet another discussion of an offset curve problem, but this one crashes with a zero offset on a simple circle. works on other curve shapes. I would expect behavior to be to simply ignore the zero offset

Weird! The zero offset is extremely slow too (18.5 secs.!?) while positive and negative values give instant results. [zero-offset-bug_2021_Jul9a] zero-offset-bug_2021_Jul9a.gh (8.6 KB) P.S. But only with circles? A different closed curve works much more quickly, though 0 offset still slows it…

[2021-07-09 14_25_58-Number persistent data] That’s an incredibly small number… actual 0 gives no problem.

hmm. numbers generated from a straightforward series command

I’m pretty sure series component is doing only what you asked it to do… check, you’ll see its inputs have already not-simple numbers. Do as Joseph just said ^

Good eye Richard, thank you joseph. but just for a head scratcher, here is the series command, there is nothing there to cause an issue [series] series.gh (3.7 KB)

thanks guys, got a flat spot on my head beating it against the wall on this one.

[image] markz: there is nothing there to cause an issue You are right. This is a Round-off error - Wikipedia . Any number is written in binary, base-2 numbering … but displayed as decimal, base-10. Decimal 0.3 is 0.01001100110011001101 in binary, that have a periodic part, so it has lost s…
