CATIA (Computer-Aided Three-Dimensional Interactive Application)

is a robust and versatile software suite developed by Dassault Systèmes, widely utilized in industries such as aerospace, automotive, and manufacturing for computer-aided design (CAD) and computer-aided engineering (CAE) purposes. Renowned for its extensive capabilities, CATIA empowers engineers and designers to create intricate 3D models, facilitating the virtual representation of products.

Featuring modules like Part Design, Assembly Design, Generative Shape Design, and Drafting,

CATIA supports parametric modeling, allowing users to efficiently define and modify design parameters. Its Digital Mock-Up (DMU) module aids in assembling and visualizing product structures in a virtual environment for design validation.

CATIA exists in two major versions, V5 and V6, with the latter introducing a more collaborative and cloud-based approach to design. The software is adept at handling large and intricate assemblies, integrating seamlessly with other Product Lifecycle Management (PLM) tools. From conceptualization to manufacturing planning, CATIA plays a pivotal role in the entire product development process, contributing to its widespread adoption and reputation as a leading CAD/CAE solution in the engineering domain.
