Synthesis of a web-based dimensional verification system for styling processes

A design methodology is proposed for a web-based collaborative system applicable to styling processes in the distributed environment. By using the developed system, design reviewers of new products are able to confirm geometric shapes, inspect dimensional information of products through measured point data and exchange views with other design reviewers on the internet. Functional requirements for the design of this web-based dimensional verification system are suggested. ActiveX-server architecture and OpenGL plug-in methods using ActiveX controls realize the proposed system. Visualization and dimensional inspection of the measured point data are conducted directly on the web; conversion of point data into a CAD file or VRML form is not required in the styling process. Dimensional verification results and design modification ideas are uploaded through markups and/or XML files during the collaboration processes. The XML files, allowing information sharing on the web, are independent of the platform. It is possible to diversify the information sharing capability among design collaborators. The validity and effectiveness of the developed system are confirmed by case studies.
