Feature-based collaborative design

With the appearance of the concept of virtual enterprise, it is necessary to develop a system that can support the collaborative work of multi-disciplinary groups distributed in different places. This paper puts forward a feature-based collaborative design system; briefly presents a model of collaborative design and the definition, classification and relationship of the features in this system; discusses key techniques related to realizing feature-based collaborative design in detail; and finally gives the architecture of the feature-based collaborative design system.
