Rotating chairs around a spline??

[ArchiMiles]

Hey, I’m using CA version 10 on a Mac M4 chip.

Anyway, I remember a long time ago there was a way to rotate (chairs in a theater setting) around a circle or spline. 

Attached is what I would like to learn how to do, but mathematically sequential and spaced.

Thank You.

Not sure if you mean V10 (which is really, really old now) or X10 (which is still old), but you might be able to do it with the transform/replicate dialog.  You can place a current point at the center of the arc and then set the number of copies, using a relative rotate angle, and then select "about current point".

 

The other way you could do this is use a distributed path.  This in my opinion might be better because then you could adjust them much easier later if needed and a path could be an arc, spline, or any other shape you need.
