In this paper, a set of common modeling method suited to the rotator model was proposed. Three-dimensional model of rotational parts as the research object were be studied,the structural features of the rotator model were analyzed, and summarized the modeling ideas and methods were summarized. them. The modeling process of rotational parts was completed using the NX 8.0 software.%总结出一套适用于常见回转体模型的建模方法。主要以回转体三维模型为对象,通过对常见回转体模型的结构特征进行分析,详述这类模型的建模思路和方法。建模过程主要借助于NX 8.0软件。
