SimLab ComposerFrom 3D model to interactive experience — in minutes, not months.

SimLab Composer consolidates mechanical simulation, code-free VR authoring and photorealistic visualization into a single application. Import from over 30 CAD and 3D formats, and produce validated assemblies, immersive experiences, training programmes and rendered output from the same scene.

Automation & Scripting

Do the repetitive work once

→Visual scripting for behaviours and batch tasks, with no code.

→Python for deeper control of scenes, materials and exports.

→Command-line batch processing for overnight conversion and rendering.

Data Security

Your models never have to leave your machine

Every step — import, conversion, rendering, animation, 3D PDF and VR packaging — runs locally on your own hardware. No cloud upload of your 3D or CAD data is required at any point.

→Confidential and export-controlled geometry stays inside your network.

→Full desktop processing — no per-render cloud queue or usage metering.

→Works offline, and fits IT policies that prohibit third-party uploads.

Batteries included

Everything you need for a complete solution is in the box — no add-ons, no developers, no extra viewers to buy.

No-code creation

Build scenes, interactions and VR training visually — no programmers needed.

Share anywhere

One click to web, 3D PDF, VR package or image — recipients need no license.

Runs on any device

Desktop, mobile, browser and VR headsets — Quest, Pico, PC VR — via the free SimLab VR Viewer.

Collect & review results

Training sessions and quizzes report learner results back to you for review and grading.

Use cases for your discipline

Same application, different outcomes. Start from the workflow that matches your team.

Mechanical & CAD

Import native CAD with the assembly tree, materials and metadata intact, then rig a working assembly, run a physics-driven mechanical simulation, or author a guided repair procedure with the correct tool enforced at every step. Review it at 1:1 scale to catch clearance and ergonomic problems before a prototype is cut.

Architecture

Import from Revit, AutoCAD, SketchUp or Rhino and walk clients through the building before it is built. Materials, lighting and layout change live in the session, measurements and notes pin to the geometry, and the whole thing hands over on a headset, a phone or a browser link.

Medical & education

Doctor-supervised medical simulations, university VR labs and K-12 lessons from one platform. Faculty edit the scene structure and logic without code, students collaborate thirty at a time, and the Assessment Portal grades every decision and reports skill progression back to your LMS.

Training & assessment

Vocational and industrial skills training for any trade — welding, electrical, HVAC, heavy machinery, emergency response. Instructors author it from their own equipment and revise it the same day, distribute to unlimited trainees through the free SimLab VR Viewer, and export scores and safety violations to any LMS.

Sales, marketing & soft skills

Virtual showrooms and configurators that let a buyer experience the product before it exists, and pitch rooms where your team rehearses the conversation that sells it. Buyers change colour, finish and layout and see it at once; record the session once and it replays on any device.

Space design

Design a space, then walk clients through it at full size — layout, materials and planting changed while they watch. Move trees, swap paving, set the sun by date and time to study shadow, or step the scene through the seasons. Up to thirty people meet in it at once, and a virtual expo needs no floor to rent.
