Abstract: Interactive rule changes made during a run time are applied to a computer-aided design model. An in-memory model is produced from a set of rules, and instructions are generated for a computer-aided design system based on the in-memory model. The in-memory model is updated based on interactive rule changes. The set of rules may be stored in a database, and the set of rules in the database may be selectively updated based on the interactive rule changes. Class files may be generated based on the set of rules, and the class files may be selectively updated based on the interactive rules changes.

Abstract: A knowledge management system captures, stores, manages, and applies rules for modeling geometric objects and related non-geometric attributes. The knowledge management system controls a computer-aided design system for modeling a geometric structure. The knowledge management system includes a knowledge management application in communication with the computer-aided design system through an application program interface. The knowledge management system also includes a central database managed by a knowledge storage application for maintaining rules and other related information. The knowledge management system also includes a knowledge acquisition application for generating rule programs for storage in the central database. The rules can relate to geometric and non-geometric attributes of the model.
