【摘 要】
以前，图形交换文件(DXF)仅限于应用在单机图形设计方面。近几年来，随着Internet的飞速发展，它的出现为世界带来了大量的网络应用。现在，Internet已成为信息发布的主要工具。网络带来的新发展很大程度上影响了图形交换文件在Internet领域上的应用，更不用说是在网络上对图形交换文件进行互动的设计，加上AutoCAD在机械、建筑、电子、航天、造船、石油化工、土木工程、冶金、农业、气象、纺织、轻工已经得到广泛的应用，对图形交换文件(DXF)进行基于网络的远程交互设计必然会有一个广阔的应用前景。在网络这个没有距离的社会，做到不同地域之间的交互设计显得尤为重要，越来越多的人希望有这样的系统能提供方便、快捷的功能以完成工作上交互的需要。本系统“基于Web的远程交互设计系统”有它的独特之处，例如，通过远端客户机读取服务端数据库中的图形数据，并在网页上对DXF格式的机械设计图、建筑模型图等等进行还原，不同地域间的用户不仅可以在终端机器上完成对DXF图形实体的浏览、缩放、移动、分层显示、查询的操作，还可以使用程序提供的绘图工具对图形进行编辑并将结果保存到服务端数据库，通过对服务器端数据库的读写操作来实现用户之间的信息交互，有助于减少工程师、建筑师和其他用户之间进行交流的障碍，并使他们可以更多地共享数字化的设计信息，使Internet成为设计工作的主要协作平台。

【Abstract】
The Design and Implement of the Remote Interactive Design System Based On Web
Department of Computer Science
Formerly, the graphic exchange file was only applied to the stand-alone terminal for the graphic design. At present, with the rapid development, Internet has brought along lots of applications on web. Internet has become the primary implement for publishing information. The development which is brought along by network has an effect on the application of Internet for graphic exchang files, particularly the interactive design for the graphic exchang files on web, in addition AutoCAD has been applied to lots of field, such as machine、architecture、electron、spaceflight、shipbuilding、industry of oil and chemistry、civil engineering、metrallurgy、agriculture、weather、spin and light industry, so it must has a wide outlook in using the remote interactive design for the graphic exchange files. Internet is a society which has no distance, it is very importment for people to design graphics by using the interactive mode in different areas, more and more people hopes that such a system that can help them to meet with the need of interaction in their jobs conveniently and rapidly. “The Remote Interactive Design System Based On Web” has its unique characteristic, such as it can use the remote terminal read the graphic data from the database which is deployed on the server, and display the plan of machine or plan of architecture which are defined to the DXF format on the pages, the user from different areas not only can finish the work such as browse、scaling、transfer、controlling the graphic layer and query, but also can use the drawing tools that are supplied by the client to edit the graphics and save the result to the database, implementing the interactive communication among people by accessing the database in the server. It is useful for the engineer、architect and other users to improve the communication with each other, they can share more digital information on design. The system makes the Internet become the primary cooperate platform.
