Disclosed is a parametric feature-based 3D CAD system that allows multiple users to simultaneously edit a parametric feature-based 3D CAD model consisting of 3D parts and assemblies of those parts (3D Model). Several CAD users, each using their own computer, phone, or tablet, can edit the same 3D Model at the same time. Editing may be separate and simultaneous&#x2014;there is no need for users to worry about locking, checking out, or otherwise restricting each other's access to 3D Models. As a result, users see each other's changes occur in real-time, and may also identify what aspects other users are actively modifying through visible Collaboration Cues.

Multiple simultaneous representations are achieved through the capture essential geometry and topology in a master graph. Object information is captured in metadata associated with elements of this graph. An algorithm builds multiple domain specific representations based on the master graph and metadata. The summary of model objects is created based on metadata. Through this abstraction, desired representations (in this case for design and for manufacturing) may be generated and presented simultaneously with associativity.
