Computer-Aided Design

Computer-Aided Design, or more commonly known as CAD, is the use of computer technology for the design of jewelry models as well as many other products.

CAD is an important industrial art and has been used extensively in many applications, including automotive, aerospace industries, industrial and architectural design, and etc. before finally being adopted by jewelery industry.

CAD is used to design lines, curves, and figures in two-dimensional (2D) space which are then used to create three-dimensional (3D) objects known as surfaces and solids. These objects often make up, in partial or whole, virtual jewellery model.

End product of CAD process, or “CAD-Model”, is a virtual product which can be viewed on a screen as if it were real. This involves viewing the object from unlimited number of angles and with incredible close-ups. CAD-Models can be made extremely accurate which allows custom jewellry features with incredibly high tolerances. With using CAD, controlling features such product weight, prong thickness, and etc. become only limited by other processes such as casting and not design. Furthermore, CAD-Models can be used to produce accurate presentations, known as “renderings”, as well as dimensional or other type of drawings of the final product.

Generally, CAD is followed by Computer-Aided Manufacturing, or CAM. This process involves the use of a CAD-Model to produce real jewellery models (patterns or cast) and making molds which are transformed into the final product using one of many manufacturing techniques.

Because CAD process can be lengthy and laborious, a sketch or a similar image of the final product to be produced prior to beginning CAD is a requirement as well as part of the Gold Tech process. Our CAD technicians use the sketch and client’s directions to produce CAD-Model to the satisfaction of the end-user.
