仿形系统在 CAD 中的拓展与应用研究

Development and Application Research of Copying System in CAD

仿形加工可大大减少设计时间，提高工作效率。然而，仿形所生成的轮廓图形不能进行查询、修改以及进一步的分析工作，且难以实现技术资料的存档。文中介绍了仿形系统在ＣＡＤ中的拓展方法，编制了仿形软件与ＣＡＤ软件的接口程序，使仿形生成的轮廓图形可方便地进入ＣＡＤ系统。

Copying Manufacturing can reduce the design time greatly and promote efficiency.But the contour figure from copying machine cannot be inqui red,modified or further analyzed.It's difficult to place the technical documment on file also.This paper offers a method of how to extend the copying machine system in CAD.The author writes the interface program between the two so that the contour figure from copying machine can easily enter the CAD system.
