What CAD technology an OEM jewelry manufacturer utilizes

Ask the supplier which application it uses and whether it can work with your design files; there is no single CAD program that every jewelry factory uses. Rhino with jewelry-focused plug-ins, MatrixGold, JewelCAD, and 3Design are examples of tools encountered in jewelry design, but a software name does not prove that a supplier can edit a particular model or prepare it for production. Request confirmation of the native file format, any required plug-ins or version, and whether the supplier will provide an editable source file or only an export such as STL. If the supplier’s system differs from yours, agree on a test file before commissioning the full model.

Do not assume that a factory can open or edit a file simply because it works in a related CAD program. Compatibility can depend on the application, version, plug-ins, and whether the file is native or exported. A neutral-format file such as STL can transfer surface geometry, but it is generally a mesh rather than the original parametric design history, so editing may be less convenient. STEP can carry solid geometry between many CAD systems, but the receiver should confirm that the file imports correctly and retains the details needed for the job. Send a representative file and ask the supplier to verify dimensions, openings, stone seats, and other critical features before design work proceeds.

A CAD model describes intended geometry; it does not by itself ensure that a cast part or stone setting will match every modeled dimension. Casting, finishing, material behavior, and the selected setting method can affect the finished part. Ask the supplier which dimensions are critical, what process allowances are applied, and how those dimensions will be checked on a sample. For stone settings, communicate the actual stone measurements and shape rather than relying only on a nominal size, and confirm how the seat and setting are assessed. Agree on acceptable variation for the specific design with the manufacturer before approving production; do not use a generic tolerance as a substitute for process-specific review.

A render helps review appearance, proportions, and presentation, but it cannot confirm that a physical part fits, feels, or functions as intended. A resin or wax-like prototype can reveal issues such as scale, wearability, and visible construction, depending on the material and method used. It is not automatically equivalent to a finished metal piece: casting, finishing, and setting can change the final result. For complex geometry, close-fitting components, or intricate stone layouts, ask whether a physical sample is appropriate and what it can validate. Record approved dimensions and design changes so visual approval is not mistaken for confirmation of every production detail.

File ownership and permitted use should be agreed in writing rather than inferred from payment for a sample or production order. Clarify whether the buyer receives the editable native file, a neutral export, or only a rendering; whether the supplier may reuse or adapt the design; and whether third-party plug-ins or licensed assets affect transfer. Also specify when files are delivered, how revisions are documented, and whether the agreement covers confidentiality and production rights. These terms depend on the parties’ contract and applicable law, so obtain clear written terms before sharing commercially sensitive designs or placing an order.

A digital model revision does not automatically require new tooling. The cost impact depends on the production route and on whether the change affects a physical mold, pattern, die, fixture, or other production aid already made. Changes to dimensions, part construction, stone layout, or assembly may also require a new prototype or additional engineering review even when no dedicated tooling is involved. Before approval, ask the supplier to distinguish design labor, sample charges, and tooling charges in the quotation. Set a revision cutoff for production and require written approval of any change that affects the sample, tooling, schedule, or quoted price.
