CAD is used in many industries, and its functions are as follows: it can be used for engineering drawing design. For example: architectural engineering, decoration design, environmental art design, hydropower engineering, civil construction, etc.
It can be used in industrial drawing design. For example: precision parts, molds, equipment, etc. Able to design garment processing. For example: clothing plate making. It can be used in electronic industry design, such as printed circuit board design.
Its characteristic is that it has perfect graphic drawing function. It has powerful graphic editing function. There are many methods for secondary development or user customization. It can convert various graphic formats and has strong data exchange ability. Support a variety of hardware devices. Support multiple operating platforms. It is universal and easy to use.

Principles of CAD drawing:
1. Drawing steps: set the map sheet → set the unit and precision → establish several layers → set the object style → start drawing.
2. The graph always uses the ratio of 1: 1. In order to change the size of the pattern, different printing scales can be set in the drawing space when printing.
3. When the pattern of a small area is processed, the scale factor value of the pattern can be reduced; On the contrary, when processing the pattern filling of a larger area, the scale factor value of the pattern can be increased.
4. Set different layers, colors and line widths for different types of primitive objects. The color, line type and line width of primitive objects are controlled by layers.
5. When drawing accurately, you can use the grid capture function and set the grid capture interval to an appropriate value.
6, don't draw a picture frame and graphics in the same picture, you should insert a picture frame in the layout, and then print out the picture.
7. For famous objects, such as views, layers, blocks, lines, text styles, printing styles, etc. The naming should not only be concise, but also follow certain rules to facilitate the search and use.
8. Set some common settings in the graphic template file, such as layer, label style, text style and grid capture (that is, save as *). DWF file). When drawing a new drawing in the future, you can click Use Template in the Create New Drawing wizard to open it and start drawing.
