AutoCAD中特征化三维造型特征单元空间快速定位

Quick Orientation of Feature Unit Space about Featurized 3D Modeling in AutoCAD

在AutoCAD进行参数化造型时,特征单元在三维空间的准确定位是造型中的一个难点。为此通过Autolisp语言编制程序实现了用户坐标系的自动确定和特征单元的快速定位。

In the process konstructing parametric modeling by AutoCAD the accurate orientation of feature unit in 3D modeling is a difficult problem. In this paper the automatic of UCS and the quick orientation of feature unit are realized by Autolisp.
