Overview
CATIA (Computer-Aided Three-dimensional Interactive Application) is Dassault Systèmes' flagship multi-platform CAD/CAM/CAE software and the gold standard for advanced freeform surface modeling. It is the primary design platform for aerospace (Boeing 777/787, Airbus A350, Lockheed Martin F-35), automotive (Tesla, Ferrari, BMW, Toyota), shipbuilding, and industrial design sectors. CATIA's surface modeling capabilities — supporting G3 and G4 curvature continuity — are unmatched in the industry, making it the tool of choice for Class-A surfacing.
CATIA is available in two primary platforms: V5 (classic standalone) and V6/3DEXPERIENCE (cloud-based platform). The software covers the complete product development process from conceptual design through detailed engineering, analysis, and manufacturing. Its Generative Shape Design (GSD) and FreeStyle modules provide unparalleled surface creation and editing. Knowledge-based engineering tools capture design rules and automate repetitive tasks.
Beyond surface modeling, CATIA includes robust parametric solid modeling, large assembly management (Digital Mock-Up), composite design, electrical wire harness routing, ergonomics and human modeling, and PLM integration through 3DEXPERIENCE. CATIA has a steeper learning curve than other CAD platforms due to its advanced capabilities and aerospace-grade precision requirements.

Why Professionals Choose CATIA
CATIA's surfacing is the industry benchmark — no other tool gives the same control over curvature-continuous Class-A surfaces that aerospace and automotive OEMs demand. Its knowledge-based engineering captures design rules for reuse across giant assemblies, which is why programs like the Boeing 777 and Ferrari bodywork are modeled in CATIA.
