Rotating Gear and Pinion

grabcad

As part of trying out something new, I created this rotating gear and pinion. The challenge here would be to have them rotate with respect to each other. So, wrote a script in AutoCAD for that.Now, according to the value of the same, both rotates. The design is quite simple and the challenge is just the adjustment here of the teeth.P.s. The video does not belong to me, I am not the maker of the video, the video only has been attached as the reference by which I created this design.
