Oval Halo Setting Ring

Welcome to RhinoArtisan! In this tutorial, we’ll guide you through a complete, production-ready workflow to build an oval center stone setting with detailed rails, pavé accents, and carved galleries, finished with a classic shank. You’ll start by creating the oval gemstone in Gem Studio, extracting clean reference curves, and building a fully symmetrical design using offsets, arcs, blends, and curve optimization.

From there, you’ll construct the setting with Sweep 2 Rails, generate precise rails using surface extraction and controlled booleans, and refine/close the solid with merge operations and loft repairs. We’ll then place gemstones using curve-driven distribution and pavé tools, add prongs and cutters with manufacturing parameters, and finish with a custom basket for the center gem. Finally, you’ll carve elegant galleries using boolean difference and boolean intersect techniques for a clean, professional result ready for rendering or production.

📌 What You’ll Learn:
✔ Creating an oval gemstone (1.5 ct) in Gem Studio and extracting the Gem Curve
✔ Building a symmetrical halo layout using offsets, divide by segments, and tangent arcs
✔ Creating smooth transitions with Blend curves, joining, fillet corners, and curve fitting
✔ Enforcing perfect symmetry using Trim + Mirror Quad reconstruction
✔ Positioning the setting relative to the gem and ring size curve (US 6.5 reference)
✔ Building the main setting volume with Sweep 2 Rails and closed seam control
✔ Forming rails via structure surface extraction, splits, offsets, and boolean difference
✔ Repairing and closing geometry using merge edges and lofts for watertight solids
✔ Extracting isocurves and preparing curve networks for consistent gem distribution
✔ Placing stones with Gems by Curve and fine-tuning spacing and alignment
✔ Adding prongs and cutters with controlled diameters and clearances
✔ Completing center opening stones using Pavé + mirrored placement workflows
✔ Creating a custom basket for the center oval (6 claws + rail adjustments)
✔ Building a classic shank with editable profiles and trimming via boolean difference
✔ Carving clean galleries using extruded cutting curves + boolean difference/intersect

📢 Why Watch This?
✅ Learn a full setting workflow: design curves → build solids → rails → stones → galleries
✅ Master symmetry and curve control for clean, repeatable professional results
✅ Create watertight, manufacturing-ready geometry optimized for production
✅ Combine curve-based gem placement with pavé detailing and prong control
✅ Use RhinoArtisan booleans to carve refined galleries with clean topology
