why it is different ??

Flip direction of 4th curve. Directions of 3 and 4 don’t match

Thanks your reply,

(1) circle direction

so …
no matter what the direction is, the reslut is the same.

ps.
but if I chage the click-1 & click-2 to the right half of the circles,
the result will be at the right half site.

so it still confuse me.
