Engineering Drawing (5th Edition)

As a classic textbook published by Chongqing University Press, Engineering Graphics (5th Edition) is authored by two senior teachers, Song Chunming and Chen Jiefeng, and serves as core learning material for students and practitioners in mechanical, civil, architectural, and other engineering fields. Having undergone multiple revisions, the 5th edition builds on the clear and rigorous style of previous editions while updating and optimizing content in light of modern engineering practice and digital trends.\n\nFrom a professional perspective, the book's value lies in its systematicity and practicality. It strictly follows the latest national drawing standards, starting from basic geometric elements such as points, lines, and planes, and progressing step by step to composite solids, expression methods for machine parts, standard and commonly used parts, and finally part drawings and assembly drawings. This organizational logic conforms to cognitive principles and helps readers build solid spatial imagination and graphic expression skills. The illustrations are precise and standard, and the examples and exercises are abundant and close to engineering practice, which is crucial for cultivating rigorous engineering thinking.\n\nParticularly commendable is that, beyond traditional descriptive geometry and mechanical drawing, the book timely incorporates basic concepts of computer drawing (such as AutoCAD), reflecting the connection between traditional knowledge and modern technology. Although it does not delve into software operation details, it points readers toward further study. Overall, this is an excellent textbook with authoritative content, complete structure, and clear teaching orientation; its value lies not only in exam preparation but also in laying an irreplaceable solid foundation for future engineering design work.
