There are some helical gear generator plugins for Fusion that I highly recommend! They handle this for you, and can do some cool stuff like adding desired amounts of backlash, or tell you the diametral pitch of each gear to make setting them the correct distance apart nice and easy. Their main disadvantage is that none of them are parametric, which may be a deal breaker depending on what you're doing. The method you show can be parametric if the base gear profile is, so that may be a huge win!
I definitely prefer knowing how to do it *without* the plugin, even if I end up using a plugin later to save time, because it takes the black-box mystery out of it, so I appreciate this kind of tutorial over something like "Step 1: install a plugin" I think you could put the tangent formula directly in as the expression rather than needing to use a separate calculator? I'll have to test that sometime. Still useful to see it demoed explicitly with the external calculator though And if my math is right, you could even "cheat" by parameterizing the other gear in terms of the other gear's angle by multiplying by the ratio of gear sizes, or ratio of number of teeth (but I'm new to all this gear stuff, so who knows)

hadn't yet heard ocular pat-down in a cad tutorial.
nice.
This was helpful and concise. Thanks for sharing!
Recommend the plug-in. Saves soo much time.
