A client required 3D models of several different roller chain assemblies for use in advertising graphics. Creating one complete roller chain assembly was enough of a challenge due to limitations of Draft->PathArray that must be used for the chain components [ viewtopic.php?f=3&t=18024 ]. Also, determining the center distance and number of links for given sprocket tooth numbers is not a trivial problem. As a result, a spreadsheet was created to calculate all of the key dimensions and to iterate on the center distance until an even number of links was achieved.

Re: Roller Chain Parametric Design
Nice example on how different workbenches and tools can be used in a single task. I didn't test it and i don't remember if i did that in the past. But i did remembered this thread:

Maybe you could try the macro to see the results it produces!
