A knowledge model of CAD knowledge may be created using a modeling language such as SysML to improve maintainability and re-usability of knowledge, thereby reducing workload. The SysML knowledge model may be stored in a knowledge repository coupled to a knowledge server. The SysML knowledge model may be accessed through the knowledge server. The SysML knowledge model may be associated with elements of a CAD model, and one or more elements of the CAD model may be linked to one or more corresponding elements in the knowledge model. Thus, when a value of one or more elements is changed in the knowledge model, the results of the change are updated substantially immediately in both the CAD model and the knowledge model and other applications using the knowledge model.
