This feature is so beastly. I'm excited about the helical options.

I had modified your previous spurgear to create helical and double helical gears with succes but I will forget about it now. https://cad.onshape.com/documents/b2236b83a162927a010c44da/w/393fc9b07175c601b500777f/e/d14706e745f09bf9149599ec

Your spurgear featurescript is really a great job. Many thanks for all the work !!

 I am trying to get the bevelgears also working with a part of your function, It is not an easy job but I  am learning.
