CAD二次开发方法研究与运用

Research and Implementation of AutoCAD Secondary Development Method

计算机辅助设计(Computer Aided Design,CAD)技术经过长时间的发展,被广泛应用到机械工程、电子工程、建筑设计、航空航天等高新科技领域,为了保证研发出的产品特性符合特殊行业的发展要求,需要对AutoCAD软件进行二次开发,添加一些特殊功能以全面提高产品设计质量。企业在发展过程中需要顺应科技领域不断发展的功能性要求,满足用户的产品需求,因此,需要改变传统工程图纸设计的单一性,做好AutoCAD二次研发工作,改进参数化绘图方法,本文基于AutoCAD二次开发,分析了机械零件参数化绘图技术。

After a long time of development,CAD technology has been widely used in mechanical engineering,electronic engineering,architectural design,aerospace and other high-tech fields.In order to ensure that the developed product characteristics meet the requirements of special industries,it is necessary to carry out secondary development of CAD software,add some special functions,to improve the quality of product design.In the process of development,enterprises need to comply with the functional requirements in the field of science and technology and meet the needs of users'.Therefore,it is necessary to change the singleness of traditional engineering drawing design,promote the secondary development of AutoCAD and improve the parametric drawing method.Based on the secondary development of AutoCAD,this paper analyzes the parametric drawing technology of mechanical parts.
