Hiya! The extremes (curve) component doesn’t work right. At least for this curve…
Bug or…?

Thanks, appreciate it!

Why you used yz plane ?
and i don’t understand why the curve is so far from grid center

my understanding is that extremes takes into consideration the Z axis of the input plane. i just wanted to show it doesn’t work right (if i manually draw a nurbs curve, it gives the expected result). Why do you think i shouldn’t use this plane if i want the left and right extremes?

what is the relevance of the grid center position relative to the curve?

No i just ask because if you draw the curve on xy plane you already choose your plane
Extremes points changed when the curve moved or rotated, i don’t know if what happened is bug or just you need steps to make it work

Hi guys,

I figured out that zoster’s curve comprises an arc-like and a line-like curve joined to each other. Then, I tried to use “Extremes” command for the line-like curve part of zoster’s curve. It was working fine. When I tried it on the arc-like part, it gave an incorrect result. I also tried to run the extremes command on another sample arc-like curve that I created. It gave wrong result again. So I concluded that it is probably a bug related to arc-like curves.

Note that I used XZ as the base plane in my experiment. Thus Y is our height.

Best,
Tolga
