With Creo Parametric, and its extensions, you can create, analyze, view, and share designs downstream using 2D CAD, 3D CAD, and parametric and direct modeling capabilities.




Catia is described as 'CATIA (Computer Aided Three-dimensional Interactive Application) (in English usually pronounced /k?'ti?/) is a multi-platform CAD/CAM/CAE commercial software suite developed by the French company Dassault Systèmes' and is a CAD software in the photos & graphics category. There are more than 50 alternatives to Catia for a variety of platforms, including Windows, Mac, Linux, Web-based and SaaS apps. The best Catia alternative is FreeCAD, which is both free and Open Source. Other great apps like Catia are LibreCAD, Autodesk AutoCAD, SOLIDWORKS and Dune 3D.
