Computer-Aided Design (CAD)

Computer-Aided Design (CAD) is a technology that utilizes computer systems to assist in the creation, modification, analysis, and optimization of a design. As a critical application of computer graphics and visualization, CAD software enables professionals in fields like engineering, architecture, and product design to create highly detailed 2D drawings and complex 3D models of physical objects. This digital approach surpasses traditional manual drafting by offering superior precision, easy modification, and the ability to integrate with further computational processes such as simulation, analysis, and computer-aided manufacturing (CAM) for technologies like 3D printing and CNC machining.
