由三维实体模型绘制组合体的“三视图”

Three dimensional compound entity model in engineering drawing

本文研究在AutoCAD中由组合体的三维实体模型 ,通过投影转化获得组合体三视图的方法。采用这种方法绘制的三视图 ,与其三维实体之间具有内在的关系 ,所以不容易遗漏图线和产生投影错误 。

The three views of the compound entity are founded in engineering drawing. This paper set up a method of getting three views from three dimensional model of entity through projection and transform based on AutoCAD. The three views generated in this way are of inherent connection with three dimension model of entity. It is not easy for designer missing drawing lines and no error of projection occurring when drawing. Also, the efficiency is higher.
