This is a simple video tutorial that wants to show how making a 3D CAD of a globoidal cam.
I've made this because it's happened that I had to drawing it but I wrong in something and there were more interference in the rollers paths.
So I've been intrigued by the argument and I looked for some video on the web but I've found only demonstration videos. So, with the help of a little literature, I reached the goal and I've done the tutorial.
