|Free form jewelry design|
Meet aesthetic, form and production requirements for intricate jewelry designs.
I have been using Rhino since 1998. After first using it for 3D rendering work, since 2003 it's been a key part of my rapid prototyping business, which covers mostly jewelry. Rhino has been the best companion for years.
However, one area I have always struggled with in Rhino is with free-form jewelry designs. In the past, I have rented a seat of Maya to design these projects with subdivision surfaces, make all my tweaks to the design while still in Maya, then export a NURBS, bring it to Rhino, and work with the model as a piece of immovable geometry.
Recently, I needed to create a branch-shaped ring with hearts in place of leaves as a gift to my wife. I had modeled a similar ring in the past using my previously described workflow, but rather than renting a seat of Maya to do the redesign, I decided to try to complete the whole project inside Rhino 4 using T-Splines.
The solution: T-Splines
I had done production work in the past using T-Splines to make free-form surfaces, and liked how easy it was to edit them, but this was my first time using them in manufacturing. I was pleased with the results. I was able to build a smooth and continuous surface that I could easily edit to cope with aesthetic, design and fabrication issues. The whole modeling process took me six hours.
