Computer aided design (CAD), and the designers who use it, produce design documentation in manufacturing, which includes product drawings, paperwork and 3D models.

CAD is an important industrial art which is used by mechanical engineers in many industries and specialisms. Computer design is much quicker and more flexible than traditional drawing boards and has revolutionised manufacturing design. It also reduced the risk of human error, although designers still need to be accurate and meticulous. These benefits have made CAD economically significant in the last 10 years.

As with many computer based disciplines, this is a fast moving area and designers have to stay up to date with developments to be at the top of their profession.
