Knowledge Fusion and Driven Approach in CAD Systems

This paper aims at establishing a direct driven relationship between design knowledge and present parametric feature-based modeling system. A knowledge fusion and driven approach is proposed to accomplish the knowledge constraint model which includes decomposition of engineering design task into knowledge primitives, then from knowledge primitives into knowledge constraints. Finally, the algorithm based on directional graph is introduced to solve the problem in the knowledge driven module of InteSolid 2.0 system.
