摘　　要：为了快速绘制三角形的内切圆和外接圆,利用CAD二次开发工具开发内切圆和外接圆快速绘制程序。所开发的程序利用DCL对话框实现人机交互,并根据用户提供的三角形的信息确定内切圆与外接圆的半径和圆心,从而实现内切圆与外接圆绘制。所开发的程序扩展了AutoCAD的功能,界面友好,提高了绘图效率,有一定的工程应用价值。In order to quickly draw the inscribed and circumscribed circle of a triangle, in this paper a program is developed by CAD secondary development. In the developed program, the DCL dialogs are used to realize theinteractions between human and computer, and the circle center and radius calculated by the basic parameters of the triangle are used to draw the inscribed and circumscribed circle. The program can extend the function of AutoCAD, it has a friendly user interface, and it can improve the drawing efficiency and has a certain engineering application value.
