Abstract: This paper presents a distributed dynamic object model that is
aligned with the concept of design history in the context of design problem
solving activities. A distributed object model is proposed as an enabling
feature for distributed CAD (Computer-Aided Design) allowing teams to work
cooperatively, accessing and exchanging information at run time in a
distributed engineering environment. The architecture of the proposed CAD
environment allows for the artifact properties to be associated with any
relevant aspect of the design process, including those related with the
artifact specification, but also with the organization hierarchy, planning and
process workflow.
