Access Control Mechanism Based on Role-based View with in Collaborative CAD
协同CAD中基于角色视图技术的存取控制*

This paper provides an access control mechanism within collaborative CAD, based on a technique we call role-based viewing. Role-based viewing enables role-based access control through geometric partitioning of 3D models. Extracting an appropriately simplified model suitable for access rights for individual designers within a collaborative design environment is driven by an elaborate access control mechanism.
