基于VB的AutoCAD二次开发标准件和常用件库建立

On Secondary Development of AutoCAD Standard Parts and Common Parts Library Creation Based on VB

为了节省机械设计过程中几何模型的建造时间，采用VB语言对AutoCAD软件进行常用件和标准件库的二次开发。首先，分析陈述利月VB语言对AutoCAD的开发原理及关键技术；接着，介绍机械零件中部分常用件和标准件与几何模型相关的直接参数；然后，利用标准件连接件中的六角螺栓库的开发过程为例介绍利用VB语言对AutoCAD的二次开发过程。实践证明利用VB语言对AutoCAD标准件和常用件库开发能够实现，且能够节省几何模型的建造时间。

In order to save the construction time of the geometric model in mechanical design process, VB language is used for secondary development of common parts and standard parts library of AutoCAD software. Firstly, the AutoCAD development theory and key technology based on VB Language is analysed. Secondly, direct parameters associated some common pieces and Standard parts of machinery parts with the geometric model is introduced. Fi- nally, taking velopment velopment model. the development of six angle bolts library in standard connector for example, AutoCAD secondary de- using VB language is introduced. The experiment shows that the use of VB language can achieve the de- of AutoCAD standard parts and common parts library, and save the construction time of the geometric
