I’m developing a new line of necklaces and need precise, production-ready CAD files that a casting house can pick up without extra re-work. You’ll be interpreting my sketches and reference images, refining the proportions, adding stone seats where required, and delivering clean, watertight models suitable for 3D printing and lost-wax casting. Please base your proposal on the full workflow—from initial concept translation through to final, manufacturing-ready files. Let me know the software you prefer (Rhino, MatrixGold, ZBrush, etc.) and the file formats you will supply. I’ll share inspiration boards and technical specs once we start, so be prepared to iterate quickly on dimensions, tolerances, and clasp mechanics. Include a detailed project proposal that shows how you tackle modelling, revisions, and final quality checks; past examples are welcome but not essential if your plan is clear. I aim for a smooth hand-off to production, so accuracy, attention to surface finish, and logical file organization will be key benchmarks for acceptance.
