CAD uses

CAD is used to design and develop products, such as buildings, bridges, highways and interstates, aircraft, ships, automobiles, digital cameras, mobile phones, TVs, clothes, shoes, and computers, just to name a few. In addition, CAD is used throughout the engineering process from theoretical design and layout, detailed engineering and examination of components to definition of manufacturing methods in the following fields: Architecture, Industrial Design, Engineering, Garden design, and Construction Building engineering, Mechanical (Mechanical Computer Aided Design), Automotive Aerospace, Consumer Goods, Machinery, Ship Building, Electronic and Electrical (Electronic Computer-Aided Design), Manufacturing process planning, Digital circuit design, Software applications, Apparel and Textile CAD.

In the field of architecture, the software package may create results in numerous formats, however, they generally provide a graphically based result that can be used to produce concept sketches used for assessments and approvals, and finally working drawings.

Computer-aided drafting often refers to the actual technical drawing element of the project, which uses a computer instead of the traditional drawing board of years gone by. The input of the design process may derive from specialized calculation packages, pre-existing component drawings, graphical images such as maps, photos and other media, or simply from hand-drawn sketches created by the designer. It is the operator's job to use the CAD software in order to mend all the components together to produce drawings and specifications that can later be used to estimate the amounts of materials needed to construct the product as well as the estimated cost of the project, and ultimately provide the detailed drawings necessary to actually produce the product.

Computer-aided drafting software is also used in Civil Engineering for site design, roads, grading and drainage, mapping and cartography. It is also used in the production surveyor's plans and legal descriptions of land, and as the input format to geographic and facilities information systems. In addition, many landscape architecture and interior designers are also using CAD software so that they can present a detailed visual design to their customers of precisely what the project will look like upon completion. This can include such items as dcor, paint color, furniture, as well as 3D images of the landscape and surrounding buildings.
