21/10/2018 - Final CAD Design - Stone Settings

So, just to add more stress to this whole project, we have to document our entire CAD process for the final cocktail ring.
Because it's such a massive task, I can only really write short notes rather than detailed prose instructions.

Anyway, here we go, my first session on the final design was whilst manning my stall at a craft fair.  Very glad I decided to buy Rhino for my laptop.

Emerald cut stone = 10x8mm, 6mm depth
Trillion cut stones = 4mm, 2.6mm depth

1mm claw cross-section, 0.2mm circle inside to position claw
Use "mirror" command to copy round stone

Another 8 circles, 1mm inside
Side view, move inner circles down to bottom of stone

Join top & bottom circles with straight line.
Use "sweep 1 rail" & "cap" to create solid claw.  Top with 1mm sphere.

The setting I've described above, was actually mark 2.  My first design (below left) was far too solid and heavy, so I re-did it with wire only.

This design also went out the window when I found it didn't fit well on the shank.
And so mark 3 (below) was born.
