Using Adobe Illustrator, how can I evenly distribute a group of objects along an arc?
Have you tried using the making two instance of an object (e.g., a circle) and then going to
Object > Blend > Make to make a Blend?
You can modify the spacing and orientation via
Object > Blend > Blend Options.
You can attach it to a path by selecting the Blend (the one you made previously) and the path and going to
Object > Blend > Replace Spline.
