I have a circle touching the intersection of two guides. I want to rotate this circle through 20° and create a copy, and repeat this 16 more times.
Figuring that I want the rotation angle to be exactly 20°, I thought I'd enter the value in the Rotation dialog. But then the circle rotates about its own center, even when I use the rotation tool to place the center of rotation on the path. Apparently the Rotation dialog resets the center of rotation.
Looked like an obvious task...
Don't bother, I found it: all I had to do is alt-click after fixing the center of rotation!
Familiarize yourself with Transform Effect (Effect>Distort & Transform>Transform).
Thanks for the tip, jet!
