Firstly, this model looks terrific. Unfortunately, patterning along a curve is not accurate to how a real chain works. In a real chain, the distance between links is measured in a straight line between centers. When you pattern points along a curve in Creo, by contrast, the distance is measured along the curve. The point-to-point distance will thus be slightly less than what you specify. If your sprocket is very large, it will be hard to notice, but with a small sprocket, it adds up quickly and produces incorrect results. I am still trying to figure out a general solution to patterning points along a curve such that the point-to-point distance is specified, and not the distance along the curve. Any ideas welcomed. I'll post back if I figure it out.
