I've searched and searched to find a way to do this (have found Marionette routes - but that seems a sledgehammer to crack a very small nut). I want to duplicate a 2D object (a symbol that contains a circle) a fixed distance apart, prob. about 14 metres, along a 2D irregular polyline - it's for a wiggly line of trees and I'm just using it to visualise how it looks and may feel.
Bonus points for doing this to a random, or fibonacci distance.
