ON EDITABILITY OF FEATURE-BASED DESIGN

Techniques needed for editing generative designs are presented. When a feature is edited, all features attached later must be re-evaluated t o satisfy the required constraints and shape references in the initial design. We describe name matching techniques that support the design reevaluation procedure. The algorithms account for failed or multiple matches. The matching uses a naming schema based on historical, topolo gical, and geometric design information that has been described in a c ompanion paper.
