基于AutoCAD平台的参数化设计的研究

Research on Parametric Design Based on AutoCAD

在机械产品设计过程中,机械零部件的结构和形状往往是相同或者是相似的,繁琐重复的设计计算和图纸绘制,降低了设计效率。本文以齿轮设计为例,研究了AutoCAD平台下参数化设计程序实现的方法,并通过ActiveX Automation开发方法,利用参数化设计技术,实现在设计过程中,只需通过修改少量参数,就可以重新由计算机自动生成新的设计图纸。

In the design process of mechanical product, many structure and shape of mechanical parts and components are same or similar. Its design calculation and drawing are duplication and inefficient. This paper researches on the programming method to realize the parametric design based on AutoCAD, and presents a gear as an example. By the ActiveX Automation technique, computer can produce a new design project and drawing only by modifying a few parameters.
