It would be great to have a parametricly driven Planetary Gear generator ADD-IN. The idea is to be able to specify the outside diameter of the Ring Gear, the Gear Ratio we are trying to attain, and then have the software calculate the tooth count on the remaining planet and sun gears to achieve the desired gear ratio. I would like to be able to set a constraint on the outside diameter of the ring gear, tied to whatever it is driving.
