What Are CAD Drawings?
Computer-aided design (CAD) is a process that allows computer users to design a variety of products and geometric shapes on-screen, rather than building them by hand. Using CAD software, one can create and modify an object to determine how it will appear and function after it is built. CAD drawings often include a computer-generated image of the design, as well as its dimensions, processes, and materials. CAD drawings may be either two dimensional (2D) or three-dimensional (3D).
