What are Knowledgeware capabilities in CATIA and how are they used?

CATIA Knowledgeware enables capturing and reusing engineering knowledge through formulas, rules, checks, and reactions. Formulas link parameters mathematically, rules enforce design guidelines automatically, checks validate design against criteria, and reactions trigger updates based on events. Knowledge templates capture best practices for automated design reuse. Applications include standardizing designs, enforcing company standards, automating repetitive calculations, and creating configurable products.
