Computer aided design. Symbolic image depicting the use of computer aided design (CAD) in aerospace. Here, a graphic of an Ariane 5 launcher is at centre. At upper right is a view of the main motor and thrust frame, and various engineering drawings and data are seen. In the bottom left is an aerospace engineer at a CAD console. CAD is invaluable to modern engineering design, as changes may be made to designs and their dependent components, tests performed and further modifications made very quickly. Once a design is fixed, data may be transferred to automated manufacturing equipment.
