'''CATIA''' (acronimo di '''Computer Aided Three dimensional Interactive Application''') è un [[CAD]]/[[CAE]]/[[CAM]] multipiattarofma. Il software è sviluppato dalla azienda francese [[Dassault Systemes]] e venduto tramite l'[[IBM]]. Il programma è, scritto nel linguaggio C++, è la pietra angolare della suite di Dassault Systemes per la [[gestione del ciclo di vita del prodotto]].

Il software, creato nella fine degli [[anni 1970|anni 70]] e i primi [[anni 1980|anni 80]] per sviluppare l'aereo da combattimento Mirage, fu adottato nelle industrie aerospaziali, autoveicolistiche, navali e in molte altre.

Prodotti concorrenti a CATIA sono [[Ugs nx|SIEMENS-NX]], [[Pro/ENGINEER]], [[SolidWorks]], [[Autodesk Inventor]] and [[SolidEdge]].

== History ==

'''CATIA''' started as an in-house development by [[France|French]] aircraft manufacturer [[Dassault Aviation|Avions Marcel Dassault]], at that time customer of the [[CADAM]] [[CAD]] software.<ref>[http://www.3ds.com/corporate/about-us/group-profile/history/ CATIA History on Dassaut Systemes official Web Site]</ref><ref>[http://www.edstechnologies.com/download/history-catia.pdf A history of CATIA by former CEO of Dassault Systemes Francis Bernard]</ref>

Initially named '''CATI''' (''Conception Assistée Tridimensionnelle Interactive'' &mdash; French for ''Interactive Aided Three Dimensional Design'' ) &mdash; 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]].<ref>[http://www.dassault-aviation.com/en/passion/history/1916-to-this-day/1965-1986/technological-revolutions.html?L=1 Technological Revolution article by Dassault Aviation]</ref>

In 1984, the [[Boeing|Boeing Company]] chose CATIA as its main 3D CAD tool, becoming its largest customer.

In 1988, CATIA version 3 was ported from the [[mainframe computer]]s to [[UNIX]].

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]].

In 1992, [[CADAM]] was purchased from [[IBM]] and the next year '''CATIA CADAM v4''' was published. In 1996, it was ported from one to four [[Unix]] operating systems, including [[IBM]] [[AIX (operating system)|AIX]], [[Silicon Graphics]] [[IRIX]], [[Sun Microsystems]] [[SunOS]] and [[Hewlett-Packard]] [[HP-UX]].

In 1998, an entirely rewritten version of CATIA, '''CATIA V5''' was released, with support for [[UNIX]], [[Windows NT]] and [[Windows XP]] since 2001.

In 2008, Dassault announced '''CATIA V6'''<ref>[http://www.3ds.com/news-events/press-releases/release/1776/1/ Dassault Systèmes Introduces V6 to the Market - Press release]</ref>. Support for any operating system other than [[Windows]] is dropped<ref>[http://www-01.ibm.com/support/docview.wss?uid=swg27012978&aid=1 PLM V6R2009 System requirements]</ref>.

==Features==

Commonly referred to as a [[dimension|3D]] [[Product Lifecycle Management]] software suite, CATIA supports multiple stages of product development ([[CAx]]), from conceptualization, design ([[Computer-aided design|CAD]]), manufacturing ([[Computer-aided manufacturing|CAM]]), and analysis ([[Computer-aided engineering|CAE]]).

CATIA can be customized via [[application programming interface]]s (API). V4 can be adapted in the [[Fortran]] and [[C (programming language)|C]] programming languages under an API called CAA. V5 can be adapted via the [[Visual Basic]] and C++ programming languages, an API called CAA2 or CAA V5 that is a [[component object model]] (COM)-like interface.

Although later versions of CATIA V4 implemented [[NURBS]], V4 principally used [[polynomial|piecewise polynomial surfaces]]. CATIA V4 uses a [[non-manifold model|non-manifold solid]] engine.

Catia V5 features a [[parametric feature based modeler|parametric]] solid/surface-based package which uses NURBS as the core surface representation and has several workbenches that provide [[Knowledge-based engineering#KBE methodology in CATIA knowledgeware|KBE]] support.

{{As of|2008}}, the latest release is V5 release 19 (V5R19).

V5 can work with other applications, including Enovia, Smarteam, and various [[Computer-aided engineering|CAE]] Analysis applications.

==Supported operating systems and platforms==

'''CATIA V5''' runs on [[Microsoft Windows]] (both 32-bit and 64-bit), and as of ''Release 18 Service Pack 4'' on [[Windows Vista 64]]<ref>Officiel Dassault Systemes Program Directory CATIA Version 5 Release 18 SP4</ref>. [[IBM AIX (operating system)|IBM AIX]], [[Hewlett Packard]] [[HP-UX]] and [[Sun Microsystems]] [[Solaris Operating System|Solaris]] are supported.<ref name='catia_v5_sysreq'> {{cite web|url=http://www-306.ibm.com/software/applications/plm/catiav5/sysreq/index.html |title=CATIA V5 System requirements |accessdate=2007-03-08 |publisher=IBM }}</ref>

'''CATIA V4''' is supported for those Unixes<ref name='catia_v4_sysreq'> {{cite web|url=http://www-306.ibm.com/software/applications/plm/catiav4/sysreq/index.html |title=CATIA V4 System requirements |accessdate=2007-03-08 |publisher=IBM }}</ref> and IBM [[MVS]] and [[VM/CMS]] mainframe platforms up to release 1.7.

'''CATIA V3''' and earlier run on the mainframe platforms.

==Notable industries using CATIA==

CATIA is widely used throughout the [[engineering]] industry, especially in the automotive and aerospace sectors. CATIA V4, CATIA V5, [[Pro/ENGINEER]], [[NX (software)|NX]] (formerly Unigraphics), and [[SolidWorks]] are the dominant systems.

===Aerospace===

[[Boeing|The Boeing Company]] used CATIA V3<!-- CATIA V4 did not exist in 1990. Boeing 777 first flight was 1994-06-12. --> to develop its [[Boeing 777|777]] airliner, and is currently using CATIA V5 for the [[Boeing 787|787]] series aircraft. They have employed the full range of Dassault Systemes' 3D PLM products, comprised of CATIA, [[DELMIA]], and [[ENOVIA LCA]], supplemented by Boeing developed applications.<ref name="bca_cad">"[http://www.boeing.com/commercial/777family/pf/pf_computing.html Computing & Design/Build Processes Help Develop the 777]." [[Boeing Commercial Airplanes]].</ref>

European aerospace giant [[Airbus]] has been using CATIA since 2001.<ref name="ab_cad">"[http://www.baselinemag.com/article2/0,1540,2089790,00.asp PLM: Boeing's Dream, Airbus' Nightmare]." [http://www.baselinemag.com Baseline].</ref>

[[Canadian]] aircraft maker [[Bombardier Aerospace]] has done all of its designing on CATIA.<ref name='COE_NewsNet'> {{cite journal|title=Bombardier Aerospace Virtual Product Definition: Achievements and Future Directions|journal=COE NewsNet |month=August | year=2001|first=Isabelle|last=Latulippe|coauthors=|volume=|issue=|pages=|id= |url=http://www.coe.org/newsnet/aug01/|format=|accessdate=2007-03-07}}</ref>

===Automotive===

Automotive companies that use CATIA to varying degrees are [[BMW]], [[Porsche]], [[Daimler Chrysler]][http://www.coe.org/resources/newsarchives/theplant.cfm], [[Audi]],<ref name='COE_Newsnet2'> {{cite web|url=http://www.coe.org/newsnet/nov03/implementation.cfm |title=Product Lifecycle Management Solutions from IBM and Dassault Systemes Boost Efficiency at Leading Premium Vehicle Manufacturer |publisher=COE Newsnet }}</ref> Volkswagen, [[Volvo]], [[Fiat]], [[Gestamp Automocion]], [[Benteler AG]], [[PSA Peugeot Citroën]], [[Renault]], [[Toyota Motor Corporation|Toyota]], [[Honda]], [[Ford Motor Company|Ford]], [[Scania AB|Scania]], [[Hyundai Motor Company|Hyundai]], [[Škoda Auto]], [[Proton (carmaker)| Proton]], [[Tata motors]] and Mahindra. [[Goodyear Tire and Rubber Company|Goodyear]] uses it in making tires for automotive and aerospace and also uses a customized CATIA for its design and development. All automotive companies use CATIA for car structures &mdash; door beams, IP supports, bumper beams, roof rails, side rails, body components &mdash; because CATIA is very good in surface creation and [[Computer representation of surfaces]].

===Shipbuilding===

Dassault Systems has begun serving shipbuilders with CATIA V5 release 8, which includes special features useful to shipbuilders. [[Electric Boat|GD Electric Boat]] used CATIA to design the latest fast attack submarine class for the [[United States Navy]], the [[Virginia class submarine|''Virginia'' class]].<ref name='conklin_virginia_class'> {{cite web|url=http://www.dsp.dla.mil/2006-DSP-conf/Conklin.ppt |title=Realizing Life Cycle Cost Savings Through Standardization |last=Conklin |first=James |work=Defense Standardization Program |publisher=Department Of Defense }}</ref>. [[Northrop Grumman Newport News]] also used CATIA to design the [[Gerald R. Ford class aircraft carrier|''Gerald R. Ford'' class]] of [[supercarrier]]s for the US Navy.<ref name='northrop_grumman'> {{cite web|url=http://www.nn.northropgrumman.com/cvn21/facts.html |title=CVN 21 Facts |publisher=Northrop Grumman }}</ref>

===Other===

Architect [[Frank Gehry]] has used the software, through the C-Cubed Virtual Architecture company, now Virtual Build Team, to design his award-winning [[curvilinear]] buildings.<ref name='CADDIGEST'> {{cite journal|title=Gehry, Dassault and IBM Too|journal=AEC Magazine|date=September/October 2003|first=Martin|last=Day|coauthors=|volume=|issue=|pages=|id= |url=http://www.caddigest.com/subjects/aec/select/103103_day_gehry.htm|format=|accessdate=2007-03-07}}</ref> His technology arm, [[Gehry Technologies]], has been developing software based on CATIA V5 named [[Digital Project]].<ref> {{cite web|url=http://www.gehrytechnologies.com/products.html |title=Digital Project |accessdate=2007-03-07 |work=Gehry Technologies }}</ref> Digital Project has been used to design buildings and has successfully completed a handful of projects.

== Future implementations ==

[[Dassault Systemes]] has announced plans to release CATIA Version 6 (V6) in mid-2008. <ref>[http://www.mcadonline.com/index.php?option=content&task=view&id=513 MCAD Online - Dassault launches Catia V6 platform<!-- Bot generated title -->]</ref>

The new interface allows designers to manipulate the 3D solid model directly rather than the feature based design approach employed in CATIA V5.
