机械CAD设计方法中基于特征的设计

The Design on Feature in Modern Machinery Design

从机械零件三维设计的角度出发,利用特征造型的技术,提出了基于特征的设计的设计方法,并分析了该方法在产品模型的表达方法上的应用.

Based on the feature construction technology, the authors presents the ideas and methods of conceptual model from 3D- design point of view. Using shaft as a demonstration, the authors analyzed and discussed the design on feature and its application.
