Integration of FBTol into CADKEY

A well-known but unsolved issue among CAD (Computer-Aided Design) modelers is their inability to advance the representation of non-shape information beyond the confines of decorative annotations. Experts recognized that this issue is the missing piece toward achieving both true product modeling and toward satisfying advanced solid-based applications' requirement for an enhanced representation of meaningful non-shape attributes--particularly product tolerances. Feature-Based Tolerancing (FBTol) is an enabling component technology that augments solid-based systems with a complete and unambiguous representation of tolerances. No commercial CAD system on the market contains the capabilities that FM and T's (Federal Manufacturing and Technologies) FBTol technology provides. This project was needed to infuse additional quality into the design of manufacturable products. Ensuring the quality of tolerance designs before delivery of designs will avoid significant costs encountered if errors were to be found later in the product life cycle. The union of CADKEY and FBTol will aid in product design defect detection and provide downstream applications with explicit non-shape information
