2. Be familiar with the major. Although some old engineers don't know much about computers, they are sometimes very efficient, even surpassing young people who are very skilled in computer operation.
Don't draw at once, think it over first. Engineering design generally has reference drawings, technical design drawings or scheme design drawings, and the possibility of drawing them out of thin air is extremely small. Then, don't draw on the plane when you receive the task. First, spend half a day or even a few days looking at pictures and thinking. Sharpening the knife is not a mistake!
4. Draw correctly, that is, actually draw according to 1: 1. Many people think drawing is too slow and sloppy. At first glance, it seems reasonable, but it is not. We draw engineering drawings. I dare say there are no items that will not be modified. How can a drawing be finished after it is finished? If so, it should be too simple. If you draw it strictly from the beginning, it will be very convenient and save time to modify it.
5. Thoroughly study this software. Take AutoCAD as an example. People can use it everywhere, but few people study it deeply. There are several ways to draw objects. Use the simplest and fastest?
6. Do some secondary development by yourself. This is a bit high, but if you do it, it will greatly improve your work efficiency. The sources of this efficiency are: a. Secondary developed software; B. After development, you have a deeper understanding of the original software and more skills.
7. Develop good habits. Generally speaking, the method that suits your habits is the best method. But wouldn't it be better if you learned the simplest method and formed good habits? I often encounter such things to remind beginners to learn a little at school. After graduation, they think that they don't need formal training, so they learn by doing. As a result, they painted at will and gradually developed bad habits. It's not easy to change when you get used to it! I suggest beginners to buy a proper book. The series of books from Introduction to Mastery is very good. Learn step by step according to the methods in the book.
