Modern feature-based CAD system can represent design intent with construction history, feature, parameterization and constraints. Until recently, standards for CAD data exchange among different CAD system were restrict to the exchange of pure geometrical information. This paper discusses the contents, formalization and characteristics of design intent of feature-based CAD models and the information exchange mode in detail. The problems of representing and exchanging the information of design intent are also discussed. An approach to mapping design intent information among CAD system is presented. According to the newly published parts of the International Standard ISO 10303, A XML neutral format of information exchange model is presented.
