This paper provides a framework for information assurance within collaborative design based on a technique we call role-based viewing. Role-based viewing enables role-based access control through geometric partitioning of 3D models. The partitioning is used to create variable level-of-detail (LOD) meshes, across both individual parts and assemblies, to provide a model suitable for access rights for individual actors within a collaborative design environment. We show how this technique can be used to implement a hierarchical set of security access privileges based on the Bell-La Padula model. The partitioning is derived from a set of access specifications for an assembly model and its parts. The authors believe that this work is the first of its kind in the field of computer-aided design and collaborative engineering.
