Learn CATIA-NX-KNOWLEDGEWARE-RULES with Real Code Examples

Knowledgeware captures design logic through rules, parameters, formulas, and checks.

CATIA uses Knowledgeware tools like Knowledge Advisor, EKL, Rules, Checks, and Design Tables.

NX uses Knowledge Fusion, Rule-Based Design, Expressions, and Reusable Knowledge Templates.

They enforce constraints, automate repetitive modeling, and prevent design-rule violations.

Extensively used in automotive, aerospace, tooling, and configurable product platforms.
