CATIA is a computer-aided design (CAD), engineering (CAE), and manufacturing (CAM) software developed by Dassault Systèmes, initially created for the Mirage jet in 1977. It features parametric modeling, fully associative design, and is widely used in industries such as aerospace, automotive, and consumer goods. The software includes various modules for mechanical design, analysis, and simulation, as well as tools for creating assembly designs and drafting.
