Necessary conditions for mechanical design:
1. Good spatial imagination (strong drawing ability) and good logical thinking (able to simulate some actions in your mind and find out the shortcomings);
2. To be able to bear hardships, overtime is necessary. Don't try to eat fat. Machinery has not accumulated for two or three years, and it is nothing. If you can't see it, you must take the initiative to learn;
Don't waste time doing research in school, learn professional courses such as engineering drawing, mechanical principle and mechanical design well, and get an excellent curriculum design and graduation design, which is better than anything else;
Of course, there are exceptions when some foreign capital corresponds to the four-level demand. It doesn't matter whether the design is good or not.
