wonder what it’s meant to do?? i mean where is it used???

This is for nothing.
It was created for a student who calculated the gearbox whithout geometry.
At least we designed his math output in real geometry…

great!!! 3D to support equations :D
I must say its pretty well detailed….

It’s great to see a complex engineering model here. We can all learn from the student’s effort and learn a little more about power transmission.

excellent job! This is the kind of models that I like to see. A+++++
