图书特色
The objective of this book is to help the readers to understand the fundamentals of computer-aided design (CAD) concepts and become familiar with the operations in CAD modeling so as to effectively use CAD approaches for mechanical product design. The commercial CAD system, UG NX is employed as the platform for CAD environment. In Chapter 1, the brief introduction to the development process of 3D modeling techniques in CAD and its applications to mechanical design are given. Following this introduction, important topics in product modeling using UG NX, including the basics of UG NX, sketch, part modeling, assembly modeling, drawing and 3D annotation are provided.
本书的目的是帮助读者了解计算机辅助设计（CAD）概念的基本原理，并熟悉CAD建模中的操作，从而有效地利用CAD方法进行机械产品设计。在商用CAD系统中，采用了UG NX作为CAD环境的平台。第一章简要介绍了三维建模技术在计算机辅助设计中的发展过程及其在机械设计中的应用。之后，介绍了使用UG NX进行产品建模的重要课题，包括UG NX的基础知识、草图、零件建模、装配建模、绘图和3D注释。
本书旨在为机械设计、制造和自动化、汽车工程、机械、工艺设备和控制工程等专业的科技类大学研究生提供教材。此外，本书还为工程专业毕业生提供了学习先进技术的参考，以支持3D CAD技术的工程设计。无
