基于Autodesk Inventor的结构特征的重复创建

在实际的设计工作中，常常会遇到大量形状相似、规格不同的结构特征的创建问题。如果这些结构特征出现在不同的零件中，使用Inventor的iFeature功能，首先创建其结构特征的iFeature，然后在其它不同的零件中导入该结构特征，便可快速生成含有该结构特征的新零件。文中给出了结构特征创建和导入的关键技术，解决了在不同零件中简便而快速地重复创建结构特征的难题，对其它系列化零件的建模具有指导意义。

Repeatedly Creating Local Structures Based on Autodesk Inventor

In designing models, designers often face creating lots of local structures which are similar in shape, yet different in specifications. If these local structures appear in different parts, we can use iFeature in Inventor. First create the iFeature of the local structure, then use this component in different parts. In this way, designing new parts is faster and easier. The author discusses the technique of creating such component and using it, which improves the productivity of creating different yet similar parts, and has guiding significance for modeling of other series parts.
