摘要
在二维特征类库的基础上，针对特定的ＣＡＤ系统，采用文本描述方法对特征类库中的特征赋予实例及描述基本几何实体，并进行相对应的转换，从而生成零件二维图形．
Bases on the feature lib in two dimension, a method, related to the description is presented .By using this method ,the feature in the feature lib are given some value and other geometric primitives are described for the given CAD system.A transformer is designed to translate the file to a computer language and generate the paramctric drawing.
