Abstract: The integration of knowledge engineering and CAD technology is one of the developing trends of CAD technology. This paper brings up the concept of general knowledge base and gives its UG/KDA-based model. On the base of it, the paper discusses how to build general knowledge base model, mainly by the object-oriented way and by the production rule way. Meantime, it gives some examples to verify its practicability and usability.
