CADD

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.
