Circular path

a while asked if had messed scripting paths in photoshop. got little response. anyway persevered hope of creating circle. kicks, understand (i must out more). turns out there isn't info out there on subject it's not possible create true circle bezier curves. i've had , i've managed circular approximation paths.

this second attempt. first on semi circle basis 2 points - circles looked oval. better feel.

enjoy!

turns out there isn't info out there on subject it's not possible create true circle bezier curves.

is indeed?

the ellipse tool (constrained) seems create decent crircular path , if pasted above , rotated cannot notice misalignments.
