机构运动简图的AutoCAD二次开发

介绍了在AutoCAD2000平台上，利用AutoCAD2000的二次开发系统和其提供的下拉菜单、图标显示菜单等控制模块程序而开发出的机构运动简图绘图软件。软件由AutoLISP语言编制而成，同时采用了屏幕图形可视化的图标菜单和下拉式菜单技术，使命令的调用极具可视化，交互性好，易用性强；程序文件设计规范使所绘的图形具备了标准化原则，从而解决了设计人员在绘制机构运动简图中存在的重复性劳动及图形不规范等问题。用程序方式实现参数化绘图可大大压缩图形占用的计算机系统资源。

DEVELOPMENT OF AutoLISP PROGRAM FOR SIMPLE FIGURE OF MECHANISMS BASED ON AutoCAD 2000

The paper develops the AutoLISP program for simple figure of mechanisms based on AutoCAD 2000 by use of the second development systems, pull-down menu, icon menu and Visual LISP Editor in it. The software adopts the screen figure visual upon icon menu, pull-down style menu and AutoLISP program technique, attaining the standardized in screen direct selection figure storehouse, and achieving the simple figure of mechanisms system standardization mapping, thereby resolved designer is living to draw the repeatability that the simple figure of mechanisms is in the pneumatic schematic diagram working the inormal figure problems and so on, and employ the distinguishing feature such as convenient using and good developing character.
