1. Theoretical study: First of all, we should study the textbooks carefully and understand the basic concepts, principles and methods. It can be done through classroom lectures, after-class review and self-study. At the same time, we should pay attention to the combination with practice and apply theoretical knowledge to practical problems.
2. Practical operation: Descriptive geometry and mechanical drawing is a practical course, so you should do more exercises to improve your drawing ability. You can take part in the experimental class organized by the school, or draw some simple graphics yourself.
3. Reference books: In addition to teaching materials, you can also read some reference books, such as mechanical drawing and engineering drawing. These books can help you understand descriptive geometry and mechanical drawing more deeply.
4. Network resources: There are many learning resources about descriptive geometry and mechanical drawing on the Internet, such as video tutorials and online courses. You can use these resources to help your study.
5. Exchange and discussion: Exchange and discussion with classmates and teachers can help you better understand and master the knowledge of descriptive geometry and mechanical drawing. You can organize group discussions or participate in academic seminars and other activities.
