What are the various ways of going about making some tank tracks. I have the dimensions that I need, but, cant think of how I would make the pattern repeating around an enclosed path. Is there a way of making one of the track parts with tread and a way of having the drive wheel drive it, in 3D, and then repeat it around a rounded rectangle. Does it need pivot points on to go around the corners? If so, how? I presume there are a million and one different designs for this. Would be nice to be able to animate it at a later date too.
