【摘要】 本文提出了一个适用于微机的基于特征的三维变量设计模型及形体重构方法。通过引入特征及约束的概念使变量设计成为可能而特征树的应用克服了以往利用CSG树进行三维变量设计的不足。该方法保存的信息还能用于后序加工。更多还原

【Abstract】 This paper presents an approach for feature-based 3D variable design, Which are suit to microcomputer. Withthe concept of feature and conastraint. it is possilble to realize vanable design. And using the feature tree can avoid thedefects caussing by traditonal CSG tree. In addition the system can present some information for censecutive processed.更多还原
