摘　　要：对CATIA的三维参数化零件特征库的建立技术和使用方法进行了研究.利用特征模型、参数化设计和程序控制的方法建立零件的通用特征库,再通过设置参数关系式,建立通用零件特征与一般零件的关系,进而生成零件特征的库文件.新建类似零件特征时可直接从零件特征库中调用,故能够大幅提高设计效率,减少设计工作量,进而缩短产品的开发周期.The development technology and utilization method of CATIA 3-D parametric part feature base were introduced.Method of using feature model,parametric design and programming controls was used to develop part feature base and parameter relational expression was designed to develop the relation between part features with ordinary part in order to form data base of part feature.When developing new similar part feature,the data base of part feature can be used so that design efficiency can be greatly improved and reduce workload and shorten product development cycle.
