- Computer-aided design (CAD) refers to the use of computer systems to assist in the creation, modification, analysis, and optimisation of a design.
- CAD software is used by engineers, architects, and other professionals to produce precision drawings or technical illustrations, which serve as blueprints for a wide range of products, from simple items to complex machinery.
- CAD enables the digital development of two-dimensional (2D) line drawings and three-dimensional (3D) models, facilitating improved accuracy, ease of editing and sharing, as well as the simulation and analysis of different aspects of a design before physical prototypes are made or construction begins.
