Technology Services

Working alongside bespoke designers and goldsmiths, CAD designers help turn hand-drawn jewellery designs into a three dimensional reality, however complicated or intricate. At Holts you can sit down with the CAD designer and discuss your ideas. Once the design has been agreed on, the CAD expert will then interpret your idea into a three dimensional object on a computer screen. The model is viewable from any angle on and any distance from the computer screen, and with the help of 'rendered' snap-shots of the virtual model, you can also see how your idea will look in precious metal and with gemstones before its even been made. You can then make any revisions to the piece before it gets cast; such is the fantastically flexible nature of CAD.
