Computer-aided design (CAD) is a process by which designers draw up specific plans using a computer. With CAD, a designer can create a realistic 3D model of anything from a small toy to a complete office building. In the context of an IWMS program, CAD is useful for providing precise floorplan diagrams and other realistic elements that represent the physical space in the office and allow users to gain a high-level view of the space they’re working with. CAD diagrams can be created to perfect scale and dimension in order to reflect the exact shape, size and features of a room, which allows for effective space planning without the use of paper blueprints. See AutoCAD.
