While CAD is quickly making the need to do technical drawings by hand a thing of the past, knowing how to do a multiple view, to-scale technical drawing is still a very valuable skill to have. Technical drawings, whether done by hand or with CAD, are essential because they show the top, end and side views of a three-dimensional object. With hand-done technical drawings, each view is generated from a grid of lines that carry over to the next view and back.
Here is an example of a technical to-scale drawing I did for a client:
From here, I transferred the design to black Canson art paper and completed the design with watercolor and gouache. The final result:
For those of you interested in learning more about technical drawings, I highly recommend Adolfo Mattiello’s book Techniques of Jewelry Illustration and Color Rendering.
