基于AutoCAD的轴零件参数化建模研究

本文以AutoCAD为软件平台,以参数化建模为向导,利用VBA工具对其进行二次开发。设计的轴生成器软件有设置中心孔、倒角、键槽(花键)、生成齿轮等功能,进一步充实、完善了AutoCAD,并以设置中心孔为例,简单说明了利用VBA进行二次开发的一般方法。本文从用户的角度,充分考虑到软件界面的可操作性,以提高三维造型效率。

The study on shaft of parameters' modeling based on auto CAD

This paper took the parameterized modeling as the guide and carried on secondary development based on AutoCAD platform by means of VBA.The functions of designed shaft generator contented setting centre hole,bevel edge and key-way(spline),generating gear,and so on.It further enriched and perfected the AutoCAD.Taking setting center hole as example,this paper explained simply the common method of secondary development using VBA.Standing users' position,this paper considered fully the maneuverability of the interface to raise the three-dimensional modeling efficiency.
