Abstract Giving engineers the ability to reuse models with little or no effort requires a different philosophy; one based on the exchange of feature information. The development of effective data exchange methodologies, both planned and market-driven, has progressed to the point that many of the obstacles to reusing product data, which slowed the design process in the past, are being addressed. However, even today, a dichotomy exists in the area of CAD integration. Despite government efforts and industry initiatives to provide CAD data exchange standards, which are applied with varying degrees of effectiveness by some design organizations, many engineers continue to rebuild models from many sources - legacy data, customers, suppliers and partners - because they often find it easier, as a result of improved CAD interfaces, to rebuild models than attempt file conversions using standardized file formats and data translation tools. While static geometry represents a starting point for updating designs and may serve the needs of complementary systems, the engineer's needs center on model features because engineering is all about changes and trade-offs. The Emergence of Intelligent Geometry Feature recognition software introduces new intelligence to a static model or reestablishes the intelligence that went into the creation of a model. XX
