特征造型软件环境下图样表达方法研究

Research on representation for engineering drawings under feature-based modeling software environment

结合已经实行的"数字化产品数据定义通则"系列国家标准,对比二维图样表达方法的优缺点,分析三维特征造型软件环境下的图样表达方式,研究了三维表达的基本形式,指出基于特征造型软件环境开展工程制图教学,应在手工绘图条件下的各种二维表达方式的基础上,充分发挥产品数字化数据定义的优势,采用最新国家标准,开展多种形式的三维图样表达的教学。

Connected with the series of national standards of Digital Product Definition Data Practices,the advantages and disadvantages of two-dimensional drawing expression method are expatiated.The basic form of three-dimensional drawing expression is analyzed under three-dimensional modeling software environment.This method takes full advantage of digital product definition data and enriches the teaching means of representation for three dimensional drawings.
