CAD系统中三维特征造型方案的描述

摘要

By the application of Inventor,the 3D features are analyzed,some factors affecting feature modeling scheme are pointed out,the feature expression formula describing 3D feature modeling scheme is introduced for design process to be well thought over.%以Inventor为三维特征造型的应用对象，分析了三维特征，指出了特征造型方案应考虑的因素，并提出了利用特征表达式进行三维特征造型方案的描述，以利于择优选用设计方案。
