1.三维实体特征概述Outline ofThe Characteristics of 3-D Entities特征造型是PrO/ENGINEER的特点之一，它是把零件看成是由特征组成的，零件的设计过程就是特征的构造过程。所有的参数的建立都是为了完成特征的创建和特征之间的相互关系，每一个特征的改变都可能改变零件的形状。因此特征是零件设计的根本

Feature-based modelingis the one of thecharacteristics ofPro /ENGINEER, features the one ofthe parts are composed by the characteristics, the designprocess of parts is characterized by tectonic processes. Inorder to complete the characteristics' creation and therelationship between changes in the characteristics andchanges in the shape of parts, allthe parameters areestablished. So characteristics are the fundamentalofdesign of parts
