Digital twins in business: what are they actually used for?

Digital twins come up more and more often, usually in connection with factories, buildings or complex products. Behind the term lies a simple idea: creating an accurate digital copy of a real object or system, so you can observe it, test it and explain it without touching the original. In 2026, this is no longer reserved for large industrial groups.

What is a digital twin?

A digital twin is a virtual representation of a physical object: a machine, a production line, a vehicle, a building, sometimes an entire process. The copy reproduces the geometry of the original and, depending on the case, its behaviour, its operating data and its constraints.

The key distinction is the link with reality. A decorative 3D model is not a digital twin. A twin comes into its own when it stays consistent with the object it represents, when you can handle it, move around it, and use it to understand or make decisions.

Why digital twins are gaining ground in 2026

Several trends are coming together. Real-time 3D has become affordable and now runs in an ordinary web browser, with no dedicated workstation. Sensors and production data are easier to collect. And AI helps make use of that data, so the model becomes more useful than a mere picture. The result is a shift from demonstrations to genuinely operational uses.

Practical uses in business

• Training in technical tasks on a machine, without taking the real equipment out of service or running any risk.
• Onboarding: introducing a new employee to an industrial site or a complex product before their first visit.
• Sales support: showing bulky equipment at full scale on the client's premises, without having to transport it.
• Maintenance: seeing inside a machine, locating a component, following a procedure step by step.
• Design and validation: testing a layout or a modification on the model before applying it for real.
• Interpretation and teaching: explaining a heritage or scientific object by letting people handle it.

Digital twins and immersive technology

Digital twins pair naturally with virtual and augmented reality. In VR, you step inside the model and practise as you would on the real thing. In AR, you overlay the twin on the real world to compare, guide or check. It is this immersive dimension that turns a digital copy into a real working tool.

Our approach at EVAVEO

We are a studio based in Saint-Didier-au-Mont-d'Or, near Lyon, and since 2016 we have been designing 3D environments and immersive experiences for industry, training and cultural interpretation. For a digital twin, the work starts from the context and the intended use, then goes all the way through to modelling and interactions, so the model is genuinely useful in the field and not just in meetings.

How to run a successful digital twin project

The right starting point is not the technology but the use. What will the twin be used for, by whom, and in what context? A model designed to train an operator does not have the same requirements as one meant to sell a product or guide maintenance.

Next comes the level of detail. Reproducing everything is expensive and adds nothing if part of it is never used. A targeted model works better: accurate where it matters, lighter everywhere else. That is also what allows it to run on the devices the company already owns.

A useful digital twin is not the one that copies everything. It is the one that answers a specific question you had about the real thing.

In short

The digital twin is no longer a trade show concept. It is a virtual copy of a real object or system that you can explore, handle and put to work for training, sales, maintenance or teaching. As is often the case, success depends not on the budget but on the choice of the first use case: precise, measurable and rooted in a real need.
