CAD Model Reuse Based on the Integrate Design History

A CAD model cannot be reused efficiently because of its incomplete design information. To solve this problem, a CAD model reuse method based on the IDH (Integrate Design History) is presented. IDH is defined as full record of modeling process and related knowledge, an extended CAD model is built as the carrier of the IDH. Based on the extended CAD model, a model reuse method is proposed by taking advantage of product design guide technology. Finally, a prototype system is developed and verifies the efficiency and feasibility of this method.
