2 Ways to Hollow Out a Signet Ring in Rhino 3D

Hollowing a signet ring isn't just "cut out the middle" — get the wall thickness wrong and it's either too heavy or too weak.

I cover two approaches: scaling a copy down with consistent clearance using CAGE EDIT for the bottom curve, then Boolean Difference to cut it out — or, from the top view, drawing a box and using Boolean Split with Show to set thickness directly.
