First, characteristics of product models in traditional design and concurrent design are compared. Therefore, thoughts of design object and design process working in the double harness are put forward. And, two typical representation methods of product model, and their localization are expatiated. Concept of generalized engineering semantic feature is defined. State of product design model is expressed. Then, an integrated representation method of product model is advanced. Based on the Pro/Engineer software platform, product-modeling system for product general information model is set up.
