You can create 3D models with Python Script. Python can be used all over Rhino3D in many different ways. Oval cabochon rings can be created programmatically much faster than you could do it manually.

- Just set the ring parameters in the ellipse_cab_params.json file. - Run the ellipse_cab_ring_builder.py file with the Rhinoceros 3D Software.

Rhino uses Python version 2.7. No need to download and install any python interpreter on your computer.

I believe that I can develop a set of tools to assist people in automating basic 3D modeling procedures. My plan involves creating many mini-programs. I hope that individual customers can choose the products they need to meet their requirements, and that bulk purchases can still be made at a reasonable price.
