摘要
三维设计软件日益普及,而参数化设计又能够大大提高设计效率。参数化设计就是用参数对结构形状相似、尺寸不同的一组零件进行尺寸约定,实现利用参数驱动图形的目的。以UGNX为支撑平台,介绍了NX具有的3种参数化设计功能,结合参数化设计在联轴器设计中的应用实例介绍了电子表格法、表达式法三维零件参数化模型的建立步骤,并创建了一个简单的联轴器零件库。
3D design software is growing in popularity,and the parametric design can greatly improve the efficiency of the design. Parametric design is to use parameters on structure of similar shape, size of a different set of parts for size agreed, achieved by the use of parameter driving the graph. This paper is supported by the UGNX platform, introduced the NX has 3 kinds of parametric design, function, introduced the application of electronic table method and the expression method of 3D parametric modeling steps, and create a simple parts library.
