CATIA is a multi-platform software suite developed by Dassault Systèmes for CAD, CAM, CAE, PLM, and 3D applications. It allows users to create and modify complex 3D parts from 2D images and supports systems engineering, model-based systems engineering, and simulation across various engineering disciplines. Additionally, CATIA's capabilities extend to the design of routed systems, facilitating the integration of manufacturing information into product development.
