摘　　要：本文基于VBA编程语言和AUTOCAD软件平台开发面向应用的标准3D参数化电子元件零件库,电子元件零件库可实现元器件3D模型的随机调用和自动布局等功能。以标准零件库中SOP和QFP封装形式器件为例给出了器件VBA建模过程。为实现零件库的参数化拓展应用,设置了各种可编辑元件尺寸参数,便于用户可对调用的元器件特性参数进行修改。结果表明,开发的电子元件零件库实现了基本功能的同时操作界面人机交互友好。Based on the VBA programming language and AUTOCAD software platform,this paper developed an application oriented standard 3D parametric electronic component library.The electronic component library can be used to realize the functions of the random calling and automatic layout of 3D models of components.Taking the SOP and QFP packaged devices in the standard parts library as an example,the device VBA modeling process is given.In order to realize the parametric expansion application of the part library,various editable component size parameters are set so that the user can modify the characteristic parameters of the called components.The results show that the developed electronic component parts library realizes the basic functions and has a friendly human-computer interaction interface.
