computer aided design

method of using specialized computers for planning electronic circuit and architectural designs

Computer-aided design (CAD) is use of a wide range of computerbased tools that assist engineers, architects  and other design professions in their design activities. It is the main geometry authoring tool within the Product Lifecycle Management process and involves both software and sometimes special-purpose hardware. Current packages range from 2D vector base drafting systems to 3D solid and surface modellers.

Computer Aided Design, method of creating designs and blueprints using a computer, CAD

<application> (CAD) The part of CAE concerning the drawing or physical layout steps of engineering design. Often found in the phrase "CAD/CAM" for ".. manufacturing".

computer simulations can be used to test product design and performance with a high degree of accuracy without physical testing (see CADCAM). It helps reduce; lead times, costs, stocks, space, waste.
