AutoCAD倒角国标标注的ARX二次开发

针对在AutoCAD2000中没有直接标注倒角的命令这一不足，利用VisualC 6．0，在AutoCAD2000环境下，开发了一个倒角国标标注的ARX应用程序。论述了编程要求和编程原理，并对倒角线方向的判断、倒角距离的计算、倒角标注指引线的生成、倒角标注文本的插入等编程中的关键问题进行了讨论。给出了标注实例。该技术已用于为某厂开发的模具设计CAD系统中。

Development of AutoCAD on Labeling Chamfer According to Chinese National Standard Used ARX

Using the tools and platform such as Visual C+ +6 0,ARX,an AutoCAD application on labeling chamfer was developed The requireme nts and principles of program were discussed Many key techniques were resolved , such as the judgment of chamfer direction, the calculation of chamfer distance , the methods of building leader line and inserting text The application was a lso illustrated by some related instances and it has been used in a CAD system o f mold design
