Computer-aided design, commonly known as CAD, is a manufacturing process that allows us to digitally create 2D drawings or 3D models of future products. CAD helps designers and engineers visualize a product's construction, before fabricating it.

Education: Most employers prefer candidates with at least an associate's degree in a relevant field such as computer-aided design, drafting, or engineering. Some colleges and vocational schools offer CAD design programs that provide comprehensive training in software applications and technical drawing techniques.
