On the integration of model-based feature information in Product Lifecycle Management systems.

•We propose a new structure for annotating CAD models that can be integrated with PLM systems.•We describe the architecture of a software system to externally manage the design information that is embedded in CAD models.•The proposed mechanism facilitates a cohesive view of product-related information within the design environment.•A prototype was developed to demonstrate the new structures and their integration with two commercial PLM systems with distinct data models.•The prototype was efficiently integrated in a typical production workflow and information was effectively stored, retrieved, and synchronized.
