Succeed with AI in Knowledge-Based Engineering
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.
Plus, when used in conjunction with SIMULIA simulation on the 3DEXPERIENCE platform, the result is a fully integrated Modeling and Simulation experience called MODSIM that truly revolutionizes your product development process.
Over the years, the value of engineering has shifted. The Experience Economy changed the focus from the product itself to how users could actually benefit from it. The Circular Economy then reoriented activity around sustainability, longevity, and resource regeneration. The Generative Economy is the next step, directly reshaping how engineering platforms operate.
In the Generative Economy, value is no longer fixed in the finished part or assembly. Instead, it evolves over time. For engineering teams, this is a fundamental shift toward a platform that encodes the reasoning behind every decision, so that knowledge builds rather than resets with each new project.
CATIA has spent 40 years capturing the engineering knowledge behind the world's most complex products. The question for the Generative Economy is how to activate it.
The answer is the combination of Generative Experiences and Virtual Companions. Generative Experiences close the loop between design and validation, while Virtual Companions make that loop intelligent. Together, they transform CATIA from a design tool into a generative platform where four decades of accumulated knowledge is applied to every engineering decision and iteration.
Unlocking a new era of innovation with 3D UNIV+RSES where the Virtual Twin meets intelligence-empowering designers and engineers through human–AI collaboration.
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 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.
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:
The design-to-validation loop that used to take days? CATIA Generative Experiences closes it before you've had your coffee.
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.
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.
