CATIA is a multi-platform software suite for computer-aided design (CAD), computer-aided manufacturing (CAM), computer-aided engineering (CAE), 3D modeling, and product lifecycle management (PLM) . It was developed by the French company Dassault Systèmes and is widely used in various industries, including aerospace, defense, automotive, and industrial equipment.

CATIA is a comprehensive software suite that incorporates CAD, CAE, and CAM, and it allows architects, engineers, designers, construction professionals, and all contributors to define, imagine, and shape the connected world. It is a versatile tool that offers advanced but still simple commands and tools that can be easily understood by engineers, designers, and architects.

CATIA has capabilities in multiple domains, including part modeling, assembly modeling, surface modeling, finite element analysis, sheet metal part design, rendering, and engineering drawing creation. It is a solid model tool that combines 3D parametric features with 2D tools and even addresses every design-to-manufacturing process.

CATIA is available in over 50 configurations, each with its own industry-specific features and functionalities. Nowadays, the most widely used version is CATIA V5, with CATIA V4 still being used in some industries, mostly in conjunction with V5. CATIA currently stands at version level 6, better known as CATIA V6.

In summary, CATIA is a versatile and comprehensive software suite that empowers professionals to innovate in product development across industries. Its integration of CAD, CAE, and CAM capabilities makes it a valuable tool for designing, analyzing, and managing new products.
