CATIA (an acronym of computer-aided three-dimensional interactive application, pronounced //) is a multi-platform software suite for computer-aided design (CAD), computer-aided manufacturing (CAM), computer-aided engineering (CAE), PLM and 3D, developed by the French company Dassault Systèmes.
CATIA started as an in-house development in 1977 by French aircraft manufacturer Avions Marcel Dassault, at that time customer of the CADAM software to develop Dassault's Mirage fighter jet. It was later adopted by the aerospace, automotive, shipbuilding, and other industries.
Initially named CATI (conception assistée tridimensionnelle interactive – French for interactive aided three-dimensional design ), it was renamed CATIA in 1981 when Dassault created a subsidiary to develop and sell the software and signed a non-exclusive distribution agreement with IBM.
In 1984, the Boeing Company chose CATIA V2 as its main 3D CAD tool, becoming its largest customer.
In 1990, General Dynamics Electric Boat Corp chose CATIA as its main 3D CAD tool to design the U.S. Navy's Virginia class submarine. Also, Lockheed was selling its CADAM system worldwide through the channel of IBM since 1978.
In 1992, CADAM was purchased from IBM, and the next year CATIA CADAM V4 was published.
In the years prior to 2000, problems caused by incompatibility between versions of CATIA (Version 4 and Version 5) led to $6.1B in additional costs due to years of project delays in production of the Airbus A380.
In November 2010, Dassault Systèmes launched CATIA V6R2011x, the latest release of its PLM2.0 platform, while continuing to support and improve its CATIA V5 software.
In June 2011, Dassault Systèmes launched V6 R2012.
In 2012, Dassault Systèmes launched V6 2013x.

Commonly referred to as a 3D Product Lifecycle Management software suite, CATIA supports multiple stages of product development (CAx), including conceptualization, design (CAD), engineering (CAE) and manufacturing (CAM). CATIA facilitates collaborative engineering across disciplines around its 3DEXPERIENCE platform, including surfacing & shape design, electrical, fluid and electronic systems design, mechanical engineering and systems engineering.
CATIA facilitates the design of electronic, electrical, and distributed systems such as fluid and HVAC systems, all the way to the production of documentation for manufacturing.
CATIA enables the creation of 3D parts, from 2D sketches, sheetmetal, composites, molded, forged or tooling parts up to the definition of mechanical assemblies. The software provides advanced technologies for mechanical surfacing & BIW. It provides tools to complete product definition, including functional tolerances as well as kinematics definition. CATIA provides a wide range of applications for tooling design, for both generic tooling and mold & die. In the case of Aerospace engineering an additional module named the aerospace sheetmetal design offers the user combine the capabilities of generative sheetmetal design and generative surface design.
CATIA offers a solution to shape design, styling, surfacing workflow and visualization to create, modify, and validate complex innovative shapes from industrial design to Class-A surfacing with the ICEM surfacing technologies. CATIA supports multiple stages of product design whether started from scratch or from 2D sketches(blueprints). 
The CATIA Systems Engineering solution delivers a unique open and extensible systems engineering development platform that fully integrates the cross-discipline modeling, simulation, verification and business process support needed for developing complex ‘cyber-physical’ products. It enables organizations to evaluate requests for changes or develop new products or system variants utilizing a unified performance based systems engineering approach.

CATIA uses the open Modelica language in both CATIA Dynamic Behavior Modeling and Dymola, to quickly and easily model and simulate the behavior of complex systems that span multiple engineering discipline. CATIA & Dymola are further extended by through the availability of a number of industry and domain specific Modelica libraries that enable user to model and simulate a wide range of complex systems – ranging from automotive vehicle dynamics through to aircraft flight dynamics.
CATIA v5 offers a solution to formulate the design and manufacturing of electrical systems spanning the complete process from conceptual design through to manufacturing. Capabilities include requirements capture, electrical schematic definition, interactive 3D routing of both wire harnesses and industrial cable solutions through to the production of detailed manufacturing documents including form boards.
CATIA offers a solution to facilitate the design and manufacturing of routed systems including tubing, piping, Heating, Ventilating & Air Conditioning (HVAC). Capabilities include requirements capture, 2D diagrams for defining hydraulic, pneumatic and HVAC systems, as well as Piping and Instrumentation Diagram (P&ID). Powerful capabilities are provided that enables these 2D diagrams to be used to drive the interactive 3D routing and placing of system components, in the context of the digital mockup of the complete product or process plant, through to the delivery of manufacturing information including reports and piping isometric drawings.
CATIA can be applied to a wide variety of industries, from aerospace and defense, automotive, and industrial equipment, to high tech, shipbuilding, consumer goods, plant design, consumer packaged goods, life sciences, architecture and construction, process power and petroleum, and services. CATIA V4, CATIA V5, Pro/ENGINEER, NX (formerly Unigraphics), and Dassault Systèmes' own SolidWorks platform are the dominant systems.
The Boeing Company used CATIA V3 to develop its 777 airliner and used CATIA V5 for the 787 series aircraft. They have employed the full range of Dassault Systèmes' 3D PLM products – CATIA, DELMIA, and ENOVIA LCA – supplemented by Boeing-developed applications.

Dassault Systèmes provides utilities to convert CATIA V4 data files so they are accessible to CATIA V5 and CATIA V6. Still, cases show that there can be issues in the data conversion from CATIA V4 to V5 from either differences in the geometric kernel between CATIA V4 and CATIA V5 or by the modelling methods employed by end users. The percentage loss can be minimized by using the appropriate pre-conversion clean-up, choosing the appropriate conversion options, and clean-up activities after conversion.
Conversion from CATIA Version 4 to Version 5 created construction problems for the Airbus A380 aircraft. These problems resulted in $6.1B of additional costs due to years of project delays when aircraft wiring was too short to make connections.<ref name="calleam.com
Transition from V5 to V6 is facilitated because they are sharing the same geometric kernel. Third-party file translators also up-convert CATIA files between versions.
CATIA competes in the high-end CAD/CAM/CAE market with Siemens NX.
