What is the use of professional certificate of CAD mechanical drawing? Can you prove your education?

1, a professional certificate cannot prove academic qualifications, and academic qualifications should be used as credentials, not professional certificates.

The professional certificate of CAD drawing can only prove that you have CAD drawing skills.

2. Mechanical drawing is a basic course of mechanical specialty in colleges and universities, which is difficult to learn, so it is the foundation of mechanical introduction.

There is no future in learning only one mechanical CAD drawing.

CAD mechanical drawing is just one of the most basic energy-saving skills in the whole mechanical industry. Although it is also a necessary skill, if you really want to enter the mechanical industry, you must also have other knowledge, such as mechanical design, technological process and so on. In a word, mechanical CAD drawing is something that everyone who studies mechanical specialty can learn, and it is not competitive.

In order to make people have a consistent understanding of the format, characters, lines, graphics simplification and symbol meaning involved in drawing, a unified specification has been gradually formulated and developed into a mechanical drawing standard. Countries generally have their own national standards, and there are also standards formulated by the International Organization for Standardization in the world.

China's national standard for mechanical drawing was formulated in 1959 and revised twice in 1974 and 1984. The items specified in the mechanical drawing standard include: drawing width and format, scale, font and drawing lines, etc. In the drawing format and format, the size of the standard drawing format and the corresponding frame size are specified.

Only the reduction ratio and enlargement ratio specified in the standard are allowed. In China, it is stipulated that Chinese characters must be written according to the long imitation of the Song Dynasty, and letters and numbers should be written according to the prescribed structure. .

Mechanical drawing mainly includes parts drawing and assembly drawing, as well as layout drawing, schematic drawing and axonometric drawing. Part drawings show the shape and size of parts and the technical requirements for manufacturing and inspecting parts; Assembly drawing expresses the assembly relationship and working principle between parts in machinery; The layout shows the position of mechanical equipment in the factory building;

The schematic diagram shows the working principle of machinery, such as the mechanism movement diagram showing the mechanical transmission principle and the pipeline diagram showing the liquid or gas conveying line. All mechanical components in the schematic diagram are represented by symbols. The axonometric drawing is a kind of stereoscopic drawing with strong intuition and a commonly used auxiliary drawing.
