How is AI used in engineering?

AI is changing engineering by automating design tasks and predicting maintenance needs. It helps create better designs quickly and improves simulations. AI tools can suggest many design options, find defects, and optimize supply chains. It also helps analyze data and gather information from documents. AI-powered assistants support engineers in their work. Virtual prototypes, made by AI, help reduce development time and costs.

The Future of Engineering with Industrial AI

Unlock the Power of Virtual Twins

Engineering is entering a new era. Not because AI has arrived, but because for the first time, it actually understands what engineers do.

With CATIA, a Virtual Twin is far more than a digital replica. It is a scientific, multidisciplinary, multi-scale, Virtual + Real representation of a product. When designed with CATIA, Virtual Twins are fully testable under any real-world conditions, allowing designers to understand how their product will perform in the real world before anything exists.

Generative Experience AI + Virtual Companion

Unlocking a new era of innovation with 3D UNIV+RSES where the Virtual Twin meets intelligence-empowering designers and engineers through human–AI collaboration.

Virtual Companions

Meet LEO, your virtual engineering companion. LEO is trained to use CATIA. Whether you're navigating a complex model you've never seen before, or pushing through hours of repetitive design changes, LEO is right there with you, every step of the way.

Drawing on deep expertise across systems, mechanical, electrical, structural, and thermal engineering, LEO doesn't just assist; he reasons, solves, and acts. Anything you can do in CATIA, LEO can do at scale. And because every suggestion comes back to you for review and validation, you always stay in control.

Generative Design Experiences

Stop designing manually in circles. With CATIA Generative Experiences, your team gets it right the first time, eliminating the costly back-and-forth between design and validation. Whatever the input, generate production-ready CATIA models in seconds:

Generate structured specification models directly from PDFs
Design features from 3D scans: turn physical objects into parametric models instantly
Complete parametric parts: from a single image to a fully defined CATIA part
Full assemblies: generated from mechanical interfaces, not built piece by piece
Drawings: production-ready documentation, generated automatically

The design-to-validation loop that used to take days? CATIA Generative Experiences closes it before you've had your coffee.

LEO brings Generative Experiences to Life

The real breakthrough happens when the generative power of CATIA and the engineering reasoning of LEO work as one.

Once a design is produced, LEO immediately applies his multi-domain engineering knowledge to interrogate it. Does it meet the structural requirements? Is it manufacturable? Does it respect the tolerance constraints? How does it perform across competing criteria like weight, stiffness, cost, or material compliance?

This is the closed loop between generation and validation, running autonomously, surfacing only what matters to you. No more manual checks. No more missed trade-offs. LEO generates, reasons, scores, and refines, then brings you the best answer, ready for your approval.

Industry World Models

Generic AI learns language. CATIA's AI understands industry.

Over four decades, CATIA has captured the world's most complex industrial knowledge, built alongside the engineers who use it every day. Industry World Models are how that knowledge is activated at scale.

They don't just generate outputs. Industry World Models produce outcomes that are physically consistent, thoroughly engineered, and aligned with the real world, before anything ever gets built.

This is the intelligence behind LEO and the CATIA Generative Experiences. An AI that doesn't approximate reality, it models it. Multimodal, physics-aware, knowledge-guided, and fully auditable: the foundation of trustworthy AI for serious engineering work.
