计算机三维实体造型在工程设计中的应用

计算机绘图技术的发展和计算机性能的不断提高，引发了工程设计的新理念，三维实体造型设计也应运而生，并以其无可比拟的优越性显示出强大的生命力。AutoCAD、Pro／E和3DMAX等绘图软件不仅可以较方便地绘制二维视图，还可以形象逼真地绘制_三维视图。利用这些软件的强大功能，对图形进行适时修改、动画控制和模拟生产过程，使计算机三维实体绘图成为越来越方便的方法。为此，论述了三维实体建模的优点．介绍了三维实体建模的思路和特点．以及采用三维实体建模对传统设计方法的影响。

Application of 3D Modeling on Engineer Designing

The development of computer drawing technology and improvement of computer performance educeld new ideas for engineering design. The design on 3D modeling appeared and shown its powerful vitality. AutoCAD,Pro/E,3D MAX and so on were not only used in 2D drawing,but also used in 3D drawing realistically. These powerful software were used to amend the drawings timely,control cartoon and simulate the production process.so computer 3D modeling drawing become convenient method.This article discussed the advantages ,the way of thinking and the trait of the 3D modeling,introduced its influences to the traditional designing method
