A Study on the Web-Based Query Technology about the Geometric Information of Parts

Collaborative product commerce requires that all members in the product life-cycle can conveniently access the product information under access control mechanism. Not only the whole geometric model of the part participates in information sharing, but also the fine-grained elements of the model should be shared among members. In this paper, we investigate the neutral storage, query, and access control method of the feature structure and information based on feature modeling technology. Together with the light-weight representation of geometric model, we realized remote distance query and access control of the feature information of parts on geometric elements level.
