Distribute objects along a path in Illustrator
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.
If these objects are identical, you can make a "scatter brush". This solution is not panaceum and needs tweaking if you want to have specific number of elements or elements exactly on both ends of the shape. Anyway it's quite flexible :).
