🧠 Explanation:
It refers to the use of computer software to create, modify, analyze, or optimize designs. CAD is widely used in engineering, architecture, manufacturing, and product design to produce precise drawings and 3D models. It helps designers visualize concepts, simulate performance, and improve accuracy, efficiency, and productivity in the design process. CAD software replaces traditional manual drafting methods, allowing for easier revisions, better documentation, and integration with other computer-aided technologies like CAM (Computer-Aided Manufacturing). This technology has revolutionized how products and structures are planned and developed across various industries.
