| 摘 要： | 提出了一种基于 B rep,CSG和 FDG的混合结构 ,它是为基于特征的参数化设计系统而设计的 .其主要特点是通过建立特征以及特征之间的约束关系来设计产品 ,避免了设计者把过多的精力放在底层的几何和拓扑关系上 ,从而提高了产品开发的效率 .

| Abstract: | On the purpose of satisfying the request of paramet ric design system based on feature, a data structure based on Brep, CSG and FDG is proposed, and the characteristi cs of products are designed through establishing features and the constraints between them. Superiority of the data structure is that the designers do not consume excess time to the geometry and topology of the low layer so that th e efficiency of design of products is improved remarkably. |
