CAD belongs to drawing software, which can draw complex engineering drawings instead of simple lines or icons, and its drawing function is very powerful. Therefore, if you draw mechanical drawings, architectural drawings, electrical drawings, etc., generally choose CAD. There are three kinds of drawings drawn by CAD, namely plan, axonometric and stereoscopic.

Application of CAD
1, application of CAD technology in manufacturing industry CAD technology has been widely used in manufacturing industry, among which machine tools, automobiles, airplanes, ships, spacecraft and other manufacturing industries have the most extensive and in-depth applications.
2. The application in engineering design mainly includes architectural design, including scheme design, three-dimensional modeling, architectural renderings design, plane landscape, architectural structure design, community planning, sunshine analysis, interior decoration and other CAD application software; Urban planning, urban traffic design, such as urban roads, elevated, light rail, subway and other municipal engineering design.
3. The application of electrical and electronic circuit CAD technology was first used in the design of circuit schematic diagram and wiring diagram. At present, CAD technology has been extended to the design of printed circuit boards (wiring and component layout), which has played a great role in the design and manufacture of integrated circuits, large-scale integrated circuits and very large-scale integrated circuits, and greatly promoted the development of microelectronics technology and computing and technology.
4. The application of simulation and animation CAD technology can truly simulate the machining process of mechanical parts, the take-off and landing of aircraft, the entry and exit of ships, the damage analysis of objects, the flight training environment, the operational policy system and the reappearance of accident scenes.
In the field of culture and entertainment, computer modeling is widely used to simulate primitive animals, aliens and various scenes that do not exist in the real world, and the animation is seamlessly combined with the actual background and actors' performances, which shines brilliantly in film production technology and makes exciting blockbusters.
