There is a free version of this library that has fewer models, materials and scripts. I recommend getting the free one first to make sure it works satisfactorily on your computer. Then, if you want the extra models, materials, and scripts, you can get the paid version. Also, you may wish to look for my YouTube channel WebdunceTV as I will be uploading tutorials about how to use this library there as soon as I can.
This paid jewelry CAD library contains...
51 Gems, 19 Gem Cutters, and 19 Gem Outlines
87 Jewelry Materials
4 Python Scripts
7 Grasshopper Scripts
Xtra Objects
Miscellaneous
NOTE: This kit is for windows computers ONLY. It doesn't work on Macs. Also, it is for Rhino6 and Rhino7 ONLY! As computers can vary, I recommend getting the free library first to make sure it works on your computer to your satisfaction and then if you want the extra models and materials you can get the paid library.
