Jewellery Technical Drawing Guide — Views, Dimensions, Materials, Notes
A technical drawing is a legibility contract between designer and CAD bench. What every technical sheet must include (views, dimensions, materials, stone spec, notes), what to leave out (marketing copy, mood text), and the three convention differences between Indian and Western jewellery drawings.
A technical drawing is a legibility contract
Between the designer and the CAD bench, the technical drawing does one job: transfer intent without ambiguity. If it succeeds, the CAD operator retopologises against it in an afternoon. If it fails, you get 3-4 revision cycles and a piece that doesn't quite match the render. Here's what makes a technical drawing legible.
What every jewellery technical sheet must include
- Views per jewellery type — Ring: Front + Top + Side. Necklace: Front. Earring: Front + Side. Pendant: Front + Side + Back. Bangle: Front + Top + Side. Bracelet: Front + Top. Brooch: Front + Side. Emit only the required set; extra views clutter.
- Dimensions on the correct axis — inner diameter on the front view of a ring; band width on the side view; shoulder taper on the top view. Every dimension has one correct home. ISO-style: extension lines, arrow-tick terminators, numeric mm value.
- Material spec block — metal karat, hallmark stamp position, plating (rhodium / rose / oxidised) if any, finish (high polish / satin / brushed).
- Stone spec table — primary stone (type, cut, shape, size, count, setting method), secondary stones (same fields), meena zones for Indian pieces.
- Design notes — 2-4 short lines on manufacturing considerations. Wall thickness constraints. Casting warnings. Assembly order. Anything the CAD bench should know but the render doesn't show.
- Design code + revision — RH-001-v3 style. Traceable across the atelier's file system.
What to leave OUT
- Marketing copy or client-facing prose — that belongs in the design brief, not on the drawing.
- Moodboard imagery — separate document.
- Colour renders — the technical drawing is either the multi-view (colour) OR the line drawing (black-on-white). Pick one per sheet.
- Prices — BOM lives on its own sheet, updates as gold rate moves.
Three Indian vs Western convention differences
- Meena zone hatching — Indian drawings often show meena colour zones with hatching or a small colour patch. Western drawings assume plain metal unless otherwise specified.
- Foil-back notation — Kundan / Polki drawings must note "foil-backed setting, chaton depth Xmm". Western prong / bezel drawings don't need this.
- Karigar assembly note — Indian drawings often specify assembly order for pieces with jaali panels and stringing (Rani Haar, Aad). Western drawings don't (assembly is inferred from the piece).
Facetra's technical-drawing pipeline
Facetra generates the views + dimension callouts + material and stone information block automatically from a confirmed multi-view. Two style modes:
- Render mode — colour multi-view with dimensions overlaid. Client-facing lookbook.
- Line drawing mode — CAD-office thin black outlines on white with dimensions overlaid. Engineering handoff to Rhino / MatrixGold / JewelCAD.
