Explain the concept of Computer-Aided Design (CAD)?
The technique of utilizing computer software to precisely generate, alter, evaluate, and optimize designs is known as computer-aided design, or CAD. It is extensively utilized in fields like product design, engineering, automotive, aerospace, and architecture.
Both 2D drawings and 3D models can be created with CAD software, allowing for precise measurements and in-depth visualization. By enabling simple modifications, real-time collaboration, and interaction with manufacturing tools, it improves the efficiency of the design process. Additionally, CAD facilitates simulation, enabling users to test a design's performance or functionality prior to construction.
