Web-based "engineering Drawing" Collaborative Learning System

Based on the network education theory, a conception model of Web-based engineering graphics collaborative Learning are presented, several aspect's of characteristic are analyzed. This system structure is based on Browser/Server, it is made up of three layers: client browser, server, database server. The courseware and the courseware's control in Internet is the most important content we have to study, and we have spent some time on the strategy of study, but it must be researched more by us.At last, we present a example of Web-Based Engineering Graphics Collaborative Learning System, by testing, we get a good effect, and then the strongpoints and the flaws of the system are discussed.
