Merge. Align. Visualize.
Import your point clouds (LAS, LAZ, E57) and place your CAD models inside your field surveys. The real and the virtual, together in a single scene.
Your surveys on one side, your models on the other
On one side, your scans and field surveys; on the other, your CAD models. Every comparison means exports, conversions and back-and-forth between applications, and gaps between the model and reality are often spotted too late.
Import your surveys
Import your laser scans and photogrammetry (LAS, LAZ, E57): the cloud displays as-is in the scene, even for the densest surveys.
Merge CAD and reality
Overlay your 3D models on the existing conditions: compare them visually against your surveys, validate your layouts, document your site progress. Import your STEP files – the recommended format – with adjustable import settings in the general settings, and import multiple files at once with parallelized import. Position your parts relative to other parts, or move them relative to their current position.
Measure with confidence
Take your measurements on your models, right in the scene: distances, surfaces and volumes, with the accuracy of your source data.
From CAD model to digital twin
Your CAD model is already a digital twin in the making. 4Reality makes it presentable and alive:
- Import it as-is. Your STEP files open directly (the recommended format) with adjustable import settings and parallelized import for large assemblies. Combine STL and IGES files and even point clouds to get a complete model.
- Dress it. PBR materials, locally generated AI textures: your data never leaves your office, and your model becomes a photorealistic scene.
- Connect it. With RealityLive (Advanced plan), the scene follows your operating data: the position of a piece of equipment in the plant is reflected in the model. From presentation twin to connected model.
Heavy point clouds, zero friction
The 4Reality engine displays and integrates your heaviest point clouds in real time.
How it works
1. Import your survey. LAS, LAZ or E57, through the same menu as your CAD files: the cloud displays as-is, with its coordinates relative to the scene origin.
2. Position it. If your survey is georeferenced, move it with the Transform tool to bring it to the right place. Then adjust point size and colors to your needs (Pro and Advanced plans).
3. Overlay and compare. Import your CAD models over the survey and compare them visually, right in the scene.
What makes the difference
The real and the planned meet. Import your CAD models and point clouds, whatever their source, into a single scene: existing conditions and the planned project side by side, for a global view of the project that neither gives on its own.
Your data stays with you. Field surveys and models are often sensitive: everything runs locally, on your workstation, including AI-generated textures.
Frequently asked questions
Which point cloud formats are accepted?
LAS, LAZ and E57, imported through the same menu as your CAD files. The cloud display settings (point size, colors, maximum point count) are available in the Pro and Advanced plans.
Is the cloud aligned to my model automatically?
No. The cloud keeps its coordinates relative to the scene origin; if it is georeferenced, you move it with the Transform tool to bring it to the right place, then overlay your models.
Do my CAD files keep their assembly structure?
Yes for STEP, the recommended format: the assembly structure is preserved on import. You can also import several files at once.
Ready to merge?
Download 4Reality and load your first point cloud: it displays as-is, ready to receive your models.
