The basic drafting functions of CAD programs are usually easy and intuitive to learn, allowing users to create and modify 2D or 3D shapes quickly and easily. Accurately drawn designs mean that there are less errors during construction, which saves time and money as well as reducing waste.ĬAD is not difficult to learn, nevertheless there are several ways to get started from following a prescribed training course to creating a drawing or model using online resources. Another advantage of CAD programs is that they enable a high degree of precision during the planning and design stages of a project. A CAD program also allows the designer to test different design options, explain complex ideas and spaces visually, and explore how a design will function and look. CAD programs allow designs to be created in 2D or 3D depending on what the desired output is, such as printed 2D drawings or digitally shared 3D models.
CAD programs have replaced this function, allowing architects, engineers and designers to create their designs digitally. In the past, construction drawings were drafted manually by hand on paper. CAD programs are used in the architecture, engineering, and construction industries to design projects and draft their construction documentation, such as construction and fabrication drawings.ĬAD stands for computer-aided drafting or computer-aided design.
