First, cultivate your own spatial imagination.
1
Spatial imagination is the key to learn this course well. Some people are born with strong spatial imagination, while others are born with weak imagination, but it doesn't matter. We can enhance this ability through training the day after tomorrow. Use the following methods, from simple three-dimensional to complex three-dimensional, and practice repeatedly, and you will soon develop a strong spatial imagination.
2
You can watch more 3D animations, have a perceptual understanding of 3D, and establish the concepts of space and 3D in your mind.
three
Look at all kinds of objects or mechanical parts in life, starting with simple rules, such as rectangular storage boxes, cups, balls and so on. After carefully observing their shapes, close your eyes, imagine them in your mind and practice them repeatedly with different geometric figures.
four
The third step is to set a position for a basic geometric figure, then observe its shape from six directions, front, back, left, right, up and down, then close your eyes and imagine the different shapes of this geometric figure in your mind when you look at it in all directions, that is, imagine the shape of each face, and practice with different geometric figures, which is also from simple to complex.
five
The fourth step is to put the basic geometry into the projection space (the projection space model can be made of waste paper boxes), close your eyes and imagine it with the projection space and parallel light. What does the plane figure look like when parallel light is projected from front to back, from top to bottom and from left to right? Practice repeatedly from simple to complex, and draw a sketch on the draft after imagination.
six
Step five, imagine the three-dimensional shape of the basic geometry from three views. The front view is a shape projected from front to back, the top view is a shape projected from top to bottom, and the left view is a shape projected from left to right. Together, the three-dimensional shape of geometry can be imagined. You can sketch on the draft when you imagine.

Second, you can learn 3D drawing software in advance.
Three-dimensional drawing software commonly used by mechanical students includes Pro/E, SolidWorks and SolidEdge. Learning 3D drawing software has the following advantages. These softwares will be used after work. It will be very helpful for mechanical students to work after graduation.
There are many stereoscopic materials in the software, which can greatly cultivate our stereoscopic impression. The aesthetic feeling and function expansion of computer drawing can greatly stimulate our interest in learning.

Third, do more exercises.
It is necessary to draw inferences from others and achieve mastery through a comprehensive study. Practice makes perfect. Draw more and practice more. Although this is a hard and meticulous job. The exercises are available in university libraries or major bookstores. You can buy one or borrow one.
end
Fourth, ask teachers and classmates more.
This is also very important. Everyone's wisdom is infinite. Great men like Confucius are not ashamed to ask questions, let alone us. Through discussion and communication, we can stimulate our inspiration and learning potential.

Matters needing attention
We need to be serious and rigorous in our study, so as to cultivate our meticulous work style.
Learning also requires persistence and resilience. Only by constant practice can we gradually get started, draw inferences from others and achieve mastery through a comprehensive study.
