Knowledgeware (CATIA)
CATIA's automation suite — Knowledge Advisor, Knowledge Expert, Engineering Optimiser, with parameters, formulas, rules, checks, and reactions.

Definition
Knowledge Advisor adds parameters and formulas to CATIA documents — a parameter named 'WallThickness' drives sketch dimensions and feature values via a formula. Knowledge Expert applies rules (e.g., 'all holes within X mm of edge must be Y mm minimum') as constraint checks. Engineering Optimiser runs design-of-experiments and optimisation studies. Reactions trigger actions on events.
Why it matters
Captured engineering knowledge becomes reusable: a Knowledgeware-driven part is configurable through parameters instead of manually edited.
Common pitfalls
- Knowledgeware rules without scope — apply to everything and slow performance.
- Hardcoded values in formulas instead of named parameters — refactoring is painful.
- Knowledgeware combined with macros redundantly — duplicate logic in two places.
CATIA Ecosystem Context
This concept is a core structural element of the CATIA drafting and engineering environment developed by Dassault Systèmes. Dassault Systèmes' high-end PLM-grade CAD — the production tool of aerospace, automotive, and class-A surface modelling.
Relevant CATIA FAQs
❓ What's the difference between CATIA and SOLIDWORKS, both Dassault products?
Different markets. SOLIDWORKS is mid-market mechanical CAD (industrial machinery, consumer products). CATIA is high-end (aerospace, automotive, very large assemblies, class-A surfacing). CATIA's learning curve, price, and capability are substantially higher.
❓ Is CATIA available for individual hobbyists?
No. CATIA is sold through VARs to enterprises and educational institutions. Hobbyists looking for similar capability use Rhino (surfacing), Plasticity (modern direct modelling), Onshape (cloud), or older perpetual versions of SOLIDWORKS via student licenses.
❓ What is the difference between V5 and V6?
V5 is the file-based desktop platform (still widely used). V6 was the predecessor to 3DEXPERIENCE — server-stored on ENOVIA V6. CATIA on 3DEXPERIENCE is the current 'V6'-equivalent track. Many organisations run both V5 and 3DX in parallel.
