Summary of college students' engineering drawing practice
First, the purpose of curriculum practice:
Master the basic operation of Auto CAD in engineering drawing, understand the format and requirements of engineering drawing, and be able to draw two-dimensional engineering drawing with Auto CAD.
Second, the task of curriculum practice:
1. Learn the basic drawing operation of Auto CAD.
2. Draw a plane engineering drawing.
3. Understand the general requirements and format of engineering drawings.
Third, the requirements of curriculum design:
Taking CAD software as an example, this course introduces the function and application of computer-aided design, and carries out some practical operations. Students are required to understand the main functions of Auto CAD, master the basic operations of Auto CAD in engineering drawing, understand the format and requirements of engineering drawing, and be able to draw two-dimensional engineering drawings with Auto CAD.
Fourth, the significance:
With the application of traditional CAD system in industry and the complexity and intelligence of modern design problems, people are no longer satisfied with using computers instead of manual drawing. Fortunately, with the development of computer graphics, artificial intelligence, computer network and other basic technologies, as well as the research of modern design theories and methods such as computer integrated manufacturing, concurrent engineering and collaborative design, CAD systems have also developed from simple two-dimensional drawing to three-dimensional intelligent design, physical property analysis and dynamic simulation, parametric design to variable and VGX (hypervariable), geometric modeling, surface modeling and solid modeling to feature modeling and semantic modeling. On the other hand, with the increasing complexity of CAD software and the practical need of interoperability between different application systems, people hope that CAD systems have excellent openness and can be assembled freely like building blocks to form different functional configurations. The research, application and gradual maturity of software engineering technology, especially component development technology, provide a solid foundation for solving this problem.

Six, experience:
Through these days of study, I have a better understanding of CAD. At first, I felt that this software was not easy to learn and was of little use. However, after a few days of study, my view on this software has completely changed. Not only is it very useful, but it is also very studious, that is, it is very simple after mastering the basic routines. It is also important to be familiar with what you want to draw, otherwise some vital specimens will be drawn inappropriately.
The goal of computer drawing is to make the design results play a role in production practice. At present, the design results are basically put into production in the form of paper drawings. At the same time, in the design unit, paper drawings are also the main object of drawing file management. Although the development direction of computer-aided design is to realize paperless design and production, except for a few giant manufacturing enterprises, most ordinary design and production units still take paper drawings as the basis for organizing design and production. Therefore, how to convert the drawings in electronic format generated by CAD design into the drawings in paper format with specified format is a problem closely related to production practice. In a sense, this step is as important as the modification of graphics and our drawing process.
Finally, thank the school leaders and teachers for giving us this opportunity to learn. If we master one more skill, we will have one more choice and one more chance to survive in a fiercely competitive society.
