How to write a jewellery CAD brief that gets it right the first time
The details that separate a smooth, one-revision project from an expensive back-and-forth — with a checklist you can copy.
A CAD model is only as good as the brief behind it. The most common cause of extra revisions isn't the designer — it's a brief that left key decisions unstated. Here is how to make yours unambiguous.
Lead with references, then explain the deltas
Images communicate faster than paragraphs. Attach two or three references, then say clearly what you want to keep and what you want to change: "this setting, but a wider band and a bezel instead of prongs."
Pin down the measurements that drive everything
- Ring size or internal diameter.
- Centre-stone dimensions and shape (or carat and cut).
- Band width and thickness / profile.
- Metal and finish, since they affect wall thicknesses.
State the deliverables and the destination
Tell us what you need to receive (for example STL for casting plus a render) and how the piece will be produced. A model destined for micro-pavé is built differently from one going straight to a printer.
Flag the non-negotiables
If there is a hallmark to leave room for, an engraving, a comfort-fit interior, or a stone you already own, say so up front. These constraints shape the geometry from the first pull.
Your copy-paste checklist
- Category and 2–3 reference images.
- Key measurements (size, stone, band).
- Metal, finish and setting style.
- Required deliverables and file formats.
- Any hard constraints (engraving, existing stone, budget).
Fill those in and your quotation comes back faster, tighter and far more likely to land in a single pass.
