基于GDI＋的WebCAD技术研究

A Study on Technology of WebCAD Based on GDI＋

WebCAD是指运行在Internet上的网络化CAD系统，是利用互连网技术扩展和完善CAD的一项新技术．GDI＋是微软．NET框架中的下一代图形设备接口，论文探讨了利用GDI＋开发WebCAD的基本方法：CAD图形元素的GDI＋表达、基本交互功能的实现、数据网上发布与传输的实现。

WebCAD is a CAD system used on the line ,which is a new technology to develop CAD based on intemet. GDI＋ is a technology in the .NetFramwork to deal with graphic. In the paper, the basic technology of GDI＋ using to design WebCAD is studied including how to design graphic element of CAD,how to design mutual function, how to issue graphic data on the intemet.
