Computer-aided design (CAD)

Definition

Computer-aided design (CAD) is a technology that uses computer systems to assist in the creation, modification, analysis, and optimization of a design. CAD software allows designers to produce precise drawings and models, facilitating the visualization and testing of concepts before they are produced in the real world. This technology revolutionized the field of design and engineering by increasing efficiency, improving accuracy, and enhancing creativity.
