Computer-aided design has become one of the important technologies of enterprise informatization, and it is an indispensable powerful tool for engineers and technicians to carry out innovative design. AutoCAD is the product of Autodesk Company, the world's leading provider of computer-aided design software. It has millions of users and has accumulated immeasurable design data resources over the years. As the flagship product and industry standard of CAD industry, the software is adopted by design engineers all over the world by virtue of its unique advantages. As an engineering design software, it provides powerful 2D and 3D engineering design and drawing functions for engineering designers. AutoCAD 20 14 is the latest version at present. With the continuous upgrading of the version and the enhancement of functions, the functions of creating graphics quickly, enjoying design resources easily and managing design results efficiently will continue to expand and deepen. In order to make domestic designers and learners use the software better and improve the level of design application, the book AutoCAD 20 14 Chinese Standard Course is published.

The author of this book comes from domestic universities and is a senior teacher in the authorized training center of Autodesk Company. The practical ideas, methods and skills introduced in the book are all combined with years of intensive lectures and practical experience of the author and designers at home and abroad. This book closely follows the outline of AutoCAD junior engineer level and engineer level certification examination of Autodesk company, and refers to the teaching practice of many universities and training institutions, and introduces and explains the main functions and new features of the software in a targeted manner, focusing on cultivating users' ability and level to fully and appropriately use software functions to solve typical application problems. The writing of this book highlights the following characteristics.

1. On the basis of AutoCAD 20 12, the new and enhanced functions of the Chinese version of AutoCAD 20 14 are added, and the systematicness and completeness of the basic content are also emphasized.

2. Highlight design examples as clues, step by step, and run the whole design process through the book. This paper introduces in detail the process of computer aided design, the norms and standards involved, and the commands and skills applied in the design process. The auxiliary materials of this book contain most of the sample files in the book, which is convenient for readers to use and is a valuable resource for training and teaching. The audio-visual teaching documents in the supporting materials are carefully produced by many designers, which greatly reduces the learning difficulty of this book and improves the learning interest.

3. Pay attention to the implementation of the relevant standards of CAD drawing in China, and guide readers to effectively combine the rich resources of AutoCAD with the national standards of standardized design.

This book has inserted many striking marks, such as "attention" and "tips", to recommend useful experiences and skills to readers.

5. This book is equipped with audio-visual teaching courseware recorded on the screen for every example that needs hands-on practice, and marked as "Practice Video" in this book, which makes it easier for readers to master the use of the software through video teaching.

This book is divided into 13 chapters, including understanding AutoCAD, setting up drawing environment, creating and editing two-dimensional graphic objects, object features and layers, accurately drawing with drawing AIDS, words and tables, dimensioning, use of blocks, layout and printout of drawings, * * enjoying AutoCAD data and collaborative design, and creating three-dimensional models and drawing sets. Among them, chapters 1, 2, 3, 4, 5 and 6 were written by He * *, and chapters 7, 8, 9, 10,1,12 and 13 were written by. The chapters of this book are closely related, with detailed steps and clear levels, forming a complete system structure.

I would like to express my heartfelt thanks to Autodesk for its great support and help in the publication of this book.
