Take the planetary gear train shown in Figure as an example. If you are using this generator to create helical gears make sure to use the radial system, otherwise, you will have to divide the "Planet distance from center" by the cosine of the helix angle for it to be correct. The module has to be the same for all gears in each stage. Helical Gear Generator add-in for fusion 360, This generator doesn't generate the actual gears themselves, instead it generates their teeth count so you can generate them yourself.
