1, if the print out of the paper version, must avoid the use of yellow; if the electronic version (black background) to avoid the use of dark blue;
2, in general, the print version of the red, green and blue + black is more eye-catching, the electronic version of the use of red, yellow, blue and green can be, but the blue color should be selected as a light blue; in the drawings.
3, the center line, point line is usually yellow, the notes are usually green, the background is usually gray, the key content or need to adjust the content is red.
CAD software is used for engineering drawing: architectural engineering, decorative design, environmental art design, plumbing and electrical engineering, civil construction and so on.
CAD software for industrial drawing: precision parts, molds, equipment and so on.
CAD software for apparel processing: mainly used for apparel plate making.
CAD software for the electronics industry: mainly used in printed circuit board design.
CAD software is widely used in civil construction, decoration, urban planning, garden design, electronic circuits, mechanical design, clothing, footwear, aerospace, light industry, chemical industry and many other fields.
Extended information:
Technology
Mainly includes interaction techniques, graphic transformation techniques, surface modeling and solid modeling techniques, etc.
Interaction techniques are essential in computer-aided design. Interactive CAD system, refers to the user in the use of computer systems for design, people and machines can exchange information in a timely manner. The use of interactive systems, people can conceptualize, while sampling, while modifying, at any time from the graphics terminal screen to see the results of each step of the operation, very intuitive.
The main function of the graphics conversion is to connect the user coordinate system with the coordinate system of the graphics output device. Translation, rotation, scaling and perspective transformation of graphics; graph transformation is realized by matrix operations.
Computer design automation computer's own CAD, aimed at automation or semi-automation of the computer's own design and development process. Research includes functional design automation and assembly design automation, including computer hardware description languages, system-level simulation, automatic logic synthesis, logic simulation, and microprogramming automation.
