基于三维模型直接生成二维视图的方法研究

RESEARCH ON THE METHOD OF 3D MODEL TRANSFORMING INTO 2D VIEWS

对Auto CAD中由三维模型生成二维视图,从三个方面进行了阐述,概要地阐述了在第一角生成基本视图及轴测视图的要点;很好地解决了生成剖视图中剖面线存在的问题及视图之间的对齐方式等难点问题。对几种生成视图命令进行了分析比较,找出最佳方法。为工程技术人员从三维模型快速方便地生成各种二维视图,从而将模型输出为标准的工程图纸提供了依据,可大大提高设计效率。

This paper addresses the method of 3D Model transforming into 2D views on Auto CAD. The paper discusses the main points of drawing the elemental views and the axonometric projection in the first quadrant angle, and solves several problems of sectional view symbol and its alignment style in drawing cut - open view. And by working over several groups of commands of drawing views, the author finds a better method. It can help technicians to create various 2- D views rapidly and conveniently from 3-D views. Therefore, it provides a basis on which the models can be output into standard engineering drawings and improves the design efficiency considerably.
