【摘要】 提出了协同CAD中信息存取的机制,这种机制是以基于角色的视图技术为基础的。通过对3D模型的几何分割,使基于角色的访问控制成为可能。提取一个被适当简化的、对协同设计单个设计者的存取权限适宜的模型,这种提取由复杂的存取机制所驱使。更多还原

【Abstract】 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.更多还原
