CAD stands for Computer-Aided Design. It refers to the use of computer software and technology to create, modify, and optimize designs for various purposes. CAD software allows designers, engineers, and architects to generate precise 2D or 3D models of objects, buildings, or mechanical components. These digital models can be manipulated, analyzed, and visualized to explore different design iterations, assess performance, and communicate ideas effectively. CAD plays a critical role in numerous industries, including architecture, engineering, automotive, and product development, enabling professionals to streamline the design process, reduce errors, and accelerate innovation.
