Can Changshu's cutting-edge optical cad draftsmen learn anything? How is the treatment? urgent

Of course, you can learn something: first, you should learn relevant software, such as Auto CAD, and then you should learn relevant manufacturing knowledge, so that the drawings you draw will not be funny. CAD draftsman is a bridge between design and manufacturing, and there are too many things to learn. Learning without secondary school foundation is not recommended. The treatment was not so good at first, but it was better later. . .
