The 3D and CAD viewer for design reviews in architecture, mechanical engineering, and plant engineering—on screen and in VR, with no cloud dependency.
Upload your models and turn static CAD data into a dynamic, protected scene that anyone can open. Only a password-protected .ml fileleaves your company—no unprotected 3D data.
Everything looks correct on the 2D plan—and yet the forklift won’t fit through the gate, the pipe collides with the beam, and there isn’t enough space for maintenance. In the digital twin, you stand in the middle of your facility on a 1:1 scale and can identify such errors in minutes, rather than on the construction site. Review designs together from the inside—and make decisions before anything is ordered, built, or produced.
PDF has become the standard because it builds trust: Anyone can open it, nothing gets lost, and nothing ends up in a third-party cloud. The .ml file follows the same logic—but for spaces, machines, and motion. Scale, light, and depth remain consistent. It arrives exactly as you save it. For everyone, every time.
And best of all: .ml shrinks even heavy 3D and CAD models to a
fraction of their original size—gigabytes become megabytes. Quick to share,
quick to open, without special hardware.
Password-protected & encrypted — only a single view leaves your home; never unencrypted 3D data.
Communication first. Meshloader makes communication via 3D models easy, secure, and fast—and brings everyone together around a single model.
In an increasingly complex world, it’s not about apps—the technology works. Our focus is on bringing people together: a workflow that brings trades and decision-makers into a model at the right time so that problems can be solved collaboratively before construction or production begins—quickly, intuitively, and securely with meshloader.
See for yourself: from CAD export to a walk-through scene in just a few minutes. Use case—Allplan export.
No presentation slides, no sample data: Upload your own CAD model and find yourself right in the middle of it all just a few minutes later—on your screen or in VR. BIM workflows in practice.

Immersive brand experience. Experience 3D models from your 3D/CAD software in virtual reality in a matter of seconds.
Working closely with leading design and engineering firms, we have spent the last five years developing meshloader XR. With just one click, you can experience 3D models effortlessly and in the highest quality in virtual reality. Optimize your workflows and present your projects in innovative ways—quickly, intuitively, and impressively realistic with meshloader XR.
Experiencing a simulation using virtual reality in a virtual space creates a significantly more immersive experience than simply viewing it on a screen. Use case: Visual Components simulation in VR.
Our goal is to bring all project stakeholders together before construction begins. By conducting a joint simulation using the digital twin, potential errors can be identified, discussed, and resolved early on. After all, errors that only surface during implementation can cause significant damage and costs. Early and clear communication therefore always pays off..
How WKO Styria and SteinerBau make their construction projects accessible as early as the planning phase — jointly reviewing, coordinating, and deciding on designs on a 1:1 scale, long before the first brick is laid.

Improve customer communication with virtual reality
meshloader imports common 3D and CAD formats such as FBX, glTF, GLB, OBJ, 3DS, DAE, USD, and IFC. Simply export from your CAD software to one of these formats.
No. You can also open and explore each model on a regular screen. With VR headsets—including Meta Quest, HTC Vive, Valve Index, Pico, Varjo, HP, and Pimax—you can also experience the model on a 1:1 scale.
You retain your original data. Only the .ml file is shared: encrypted, password-protected, and without any unencrypted 3D raw data. Recipients can view the scene but cannot extract any CAD data.
The .ml format is meshloader's container format for 3D scenes—just as PDF is for documents, .ml is for 3D models: consistent across all platforms, true to scale, up to 50% smaller than the source file, and password-protected.
Yes. In multi-user mode, multiple participants can enter the same scene—ideal for design reviews with clients, specialists, or distributed teams.
There's a free version to get you started; you can find premium subscriptions and all the terms and conditions on our Pricing page.
meshloader XR is primarily used in architecture and construction (including BIM workflows), in mechanical and plant engineering, and by design and engineering firms—anywhere teams collaborate to review and make decisions on 3D and CAD designs during virtual walkthroughs before construction or production begins.
