Rewrote it and now you can dial the different diameters (why did i want to scale?)
Fixed the intersections but can’t find how to extrat the piece of ray between the teeth extremities…
But i have an offset problem for the outer gear (a difference in radius obviously)…
Went the radial way, easier to make the lines but intersections dont match, and can’t get the ‘every’ other gear yet culling.
