This book adopts the format of ChineseEnglish bilingual comparison, aiming to create favorable conditions for bilingual teaching. This book has 10 chapters and introduces the knowledge of engineering drawing systematically, including basic knowledge of drawing, basic knowledge of orthogonal projection, solids and their intersections, composite solids, axonometric projections, general principles of representation, standard parts and commonly used parts, detail drawings, assembly drawings, and other drawings, etc. This book links the demonstration animations of solids, parts, and assemblies in the form of QR codes, so as to facilitate students’ imagination and understanding of patterns, and improve their spatial visualization ability. This book provides PowerPoint files, syllabus, and demonstration animations, and teachers who choose this book as the textbook can download them free of charge from the website of China Machine Press Education (www.cmpedu.com). This book can be used as a textbook for the course of “Engineering Drawing” for students majoring in mechanical engineering and similar majors (72~108 class hours) and students majoring in science, engineering, economy and management (36~64 class hours), as well as students of some engineering majors in higher vocational colleges and higher professional schools. This book is also a good choice as a reference book for engineering and technical personnel and enterprise managers engaged in engineering design and manufacturing. 全书采用英汉对照的编排形式，为双语教学创造了良好的条件。全书共10章，系统地介绍了制图基本知识、正投影基础知识、立体及其交线、组合体、轴测图、图样画法、标准件和常用件、零件图、装配图、其他工程图等内容。本书以二维码的形式链接了立体、零件、装配体等的原理动画，便于学生想象和理解图样，提高空间想象能力。本书配有电子课件、教学大纲和模型动画等资源，选用本书的教师可以登录机械工业出版社教育服务网（www.cmpedu.com）免费下载。 本书可作为本科院校机械类和近机械类专业的“工程制图”课程（72~108学时）的教材，也可作为理、工、经、管等专业“工程制图”课程（36~64学时）的教材，还可作为高职高专等院校相关专业课程的教材，并且可供从事工程设计与制造的工程技术人员和企业管理人员参考。
