基于AutoCAD环境下常用结构的参数化设计

The parameterized design of configuration in common use based on the AutoCAD

AutoCAD是机械设计人员最常用的绘图工具,功能非常强大,但常因缺乏常用结构图形库而影响绘图效率,为此,论文提出在AutoCAD环境下采用AutoCAD VBA方式对机械图形中的常用结构进行参数化设计的解决方案。由于常用结构的开发方式类似,便以轴类零件中键槽结构的主视图和剖面图为例,讲述了Access数据库的构建方法、利用ADO方式来开发数据库的过程和编程实现最终图形的过程。

The AutoCAD is the most usual drawing software of mechanical designer. Its function is very powerful. But it may produce an effect on the drawing efficiency because of the lack of usual configuration. So the paper advances a solving plan to use the AutoCAD VBA to common use of mechanical drawings based on the AutoCAD. do some parameterized design of configuration in Owing to common configuration＇s similar development means, this paper gives an example of the keyway＇s front view and section drawing. It tells about how to structure the Access database, how to use ADO to develop the database and how to program to finish drawing.
