【摘要】 本文提出了一种图象处理与特征造型相结合的造型手段，利用图象处理的技术把三维布尔运算转化为在一维区间上处理，从而避免了实体造型中布尔运算的不稳定性．特征信息的加入使参数化修改成为可能，并在修改时自动进行关联性检查，方便了设计人员的设计与修改．该造型手段保存的信息能用于后序加工．更多还原

【Abstract】 This paper presents an approach which associates feature-based modelling with image processing. With the techniques of image processing,R3 Boolean operations can be processed in R1 region and the unstableness caused by boolean operations can be avoided.Using the concept of feature makes it possible to realize pararnetric design.In addition,the system can check the correlativity automatally after modifing parameters and can preserve some information for consecutive processes.更多还原
