CAD stands for computer-aided design is a technology used by engineers architects, and construction managers. CAD facilitates the drafting of construction documentation, exploration of design idea, the visualization of concepts, and it allow one to simulate how a design perform in the real world. It can be used to create two-dimensional (2D) drawings or three-dimensional (3D) models.
By using CAD, the designer is able to optimize and streamline their workflow, increase productivity, improve the quality and level of detail of their designs, improve communication between their team and often contribute to a manufacturing design database.
Digital manufacturing and CAD are frequently used together. Computing-assisted design and manufacturing (CAD/CAM) software is used for designing products such as electronic circuit boards in computers.
