How to learn mechanical drawing well (vocational high school)

First of all, if you are engaged in mechanical industry, mechanical drawing is very important. Drawing is the language of industry, which has many extensions. You can use it in architecture. Mechanical drawing can't be practiced in a few days or a period of time. What she needs is spatial imagination. Therefore, the foundation should be solid and the three views should be learned well. I find it difficult to cut and intersect lines. Anatomical drawings, parts drawings and assembly drawings should be well learned. He has a lot of knowledge to remember. Line drawing and marking methods should be remembered, because painting can't be drawn. If you don't conform to the regulations, the drawings can't be used, and others will laugh at you for not understanding. I was deeply influenced by it.

Learning method: 1, you must remember what you should remember in the textbook.

Don't be lazy in your exercise books. Do it one by one. If you don't understand, think for yourself first, and then ask others.

3, long review, read the questions I have done before several times. Do it again, you will have a deeper understanding and slowly sum up your ideas.

4, read more textbooks, remember more, especially in the back, marking and selecting tolerances is very important. I have been in contact with mechanical drawing for 5 years, and there are still many regulations to consult.
