摘要
通过对组合体构造特征的分析，讨论了在组合体读图ＣＡＩ课件中组合体数据模型的建立方法，提出了综合利用实体造型技术中的ＣＳＧ法、Ｂ－ｒｅｐ法和线架法，引入各种特征参数，从而构造组合体的特征模型。
By analying the characteristic of geometric combination, it is discussed a method to construct the data model of geometry in CAI system about interactive reading and drawing. Using CSG algorithm B-rep algorithm and edag-vertex algorithm of sold modelling technique, the feature model with the characteristic parameteris established.
