Computer-aided design systems, commonly known as CAD, are software applications used by engineers, architects, drafters, artists, and designers to create, modify, analyze, and optimize digital designs. These systems allow for the creation of two-dimensional (2D) drawings and three-dimensional (3D) models. The primary advantage of CAD is its ability to produce precise and detailed designs that can be easily edited and iterated upon, saving time and resources compared to traditional manual drafting methods.

CAD software enables users to create geometric models, which can represent objects with high accuracy. These models can then be used for various purposes, including visualization, simulation, and manufacturing. For instance, 3D CAD models can be used to generate toolpaths for computer-aided manufacturing (CAM) systems, directly translating a design into a physical product. Furthermore, CAD systems often integrate with computer-aided engineering (CAE) tools, allowing for structural analysis, thermal simulation, and other performance evaluations before a physical prototype is built.

The evolution of CAD has seen significant advancements, moving from basic 2D drafting to sophisticated 3D parametric modeling and even generative design capabilities. Parametric modeling allows designers to define relationships between design elements, so that changing one parameter automatically updates related parts of the model. Generative design uses algorithms to explore numerous design possibilities based on specified constraints and objectives, often resulting in innovative and optimized forms that might not be conceived through traditional design processes. CAD systems are fundamental tools in a wide range of industries, including automotive, aerospace, architecture, product design, and entertainment.
