摘要
本系统以通用绘图软件包ＡｕｔｏＣＡＤ为支撑软件，用ｐａｓｃａｌ语言编程，实现了变参数绘图，以人机交互方式对数据进行修改和维护，建立友好人机界面，在单用户微机上完成伸缩臂图形的自动输出．
In the software system presented in this paper,a figure processing tool with the common Auto CAD software package has been developed.As a result,apractlcal software system used in drawing the extensible cantilever has been set up.
