Many CAD application developers have improved user interfaces and connectivity supports that enable the incorporation of online information and web applications in a convenient manner. The representing difference involves numbers of steps such as uploading 3D model data file to the STL converting server, calculating their differences and visualizing them on the webpage. This paper describes steps in involved web based revision control system supporting most of CAD native formats. The C#, JavaScript programming language, PHP technique, and MySQL database system have been used to develop the framework and some special technique such as Constructive Solid Geometry (CSG) and WebGL technology have been used in the system. We conclude with a discussion of some of the issues raised by the project and the steps underway to address them.
