Free online IFC viewer
Open any .ifc file in 3D in your browser and review its storeys, element tree and properties.
No sign-upThe file never leaves your deviceIFC2x3, IFC4 and IFC4.3
Available in VisionHub
Walk mode
Walk through the model in first person, as if you were on site: WASD or arrow keys to move, Q and E to go up and down, and the mouse to look around.
Available in VisionHub
Measurements
Measure distances, areas, heights and volumes on the model, snapping to vertices and edges. Each measurement can be renamed, and point clouds can be measured too.
Available in VisionHub
Point coordinates
Click any point of the model or point cloud and read its coordinates: easting and northing, latitude and longitude, the reference system (EPSG) and a Google Maps link, when the model is georeferenced.
Available in VisionHub
Views
Preset views (front, back, sides, top and bottom) and custom views you save to return to the same framing whenever you want.
Available in VisionHub
Compare with the site camera
Align the 3D model with the real image from your site cameras by picking point pairs, adjust the model opacity and compare design with what was built, using the image from any day.
Available in VisionHub
Layers
Overlay several IFC models with point clouds and Gaussian Splatting in the same scene and set visibility, opacity and point size per layer.
Available in VisionHub
Category filter
Show or hide whole IFC categories (walls, slabs, windows, columns…) from a searchable list.
Available in VisionHub
2D drawings on the model
Import PDF or image drawings, anchor them to their storey, align them with two points or a known distance and compare them with the model in top view.
Available in VisionHub
Scene options
Sun position, sunlight and ambient light, shadows, grid, interior faces and visual styles: normal, edges and flat.
Available in VisionHub
Project models
Models stay in the project and open with fast loading: IFC, LAS, LAZ, COPC and E57 point clouds, and Gaussian Splatting. Your team works on the same files.
Available in VisionHub
Tree by class, type and material
Besides the spatial tree, reorganise the model by IFC class, type or material, and search any element by name.
How to use the IFC viewer
Open the model
Drag the .ifc onto the viewer or click “Choose file”. No model at hand? Try the sample model.
Move around
Left button to orbit, right button to pan, wheel to zoom. On mobile, one or two fingers and pinch.
Inspect an element
Click a wall, slab, window or column to see its attributes, property sets and quantities.
Look inside
Hide or isolate storeys and elements, and turn on the height section to see inside the building.
Free or with VisionHub
The free viewer is for opening and reviewing an IFC. With VisionHub the model is worked on alongside the site: everything you see locked in the viewer.
Free viewer
- One model at a time, in IFC2x3, IFC4 or IFC4.3
- 3D navigation, fit view and height section
- Storeys and elements you can hide, show or isolate
- Spatial tree and properties of every element
- Nothing is uploaded or saved. Speed depends on your device: on mobile, stick to small models
With VisionHub
- The model aligned with your site camera image from any day, to compare design with what was built
- Distance, area, height and volume measurements, on point clouds too
- 2D drawings as PDF or images, anchored to their storey and compared with the model
- Several IFC models overlaid in the same scene, together with LAS, LAZ, COPC and E57 point clouds and Gaussian Splatting, in your team’s project
- Walk mode, saved views and georeferenced coordinates of any point
- Category filter, tree by class, type and material, and scene options with sun and shadows
Your model never leaves the browser
The viewer processes the IFC with WebAssembly on your own device. There is no upload to VisionHub or third-party servers: the file is not sent, not stored, and is gone when you close the tab. You can check it yourself: load a model, go offline, and it keeps working.
That is the practical difference from online IFC viewers that require sign-up or upload the file for conversion: here a confidential client model can be reviewed without leaving your machine.
What is an IFC file
IFC (Industry Foundation Classes) is the open format for exchanging BIM models between different applications. It is maintained by buildingSMART and standardised as ISO 16739. A model exported from Revit, Archicad, Allplan, Tekla or any other BIM tool opens in any IFC viewer without the authoring software.

An IFC file is more than geometry. Every element carries its type (IfcWall, IfcSlab, IfcWindow, IfcColumn…), the storey and building it belongs to, its property sets (materials, fire rating, whether it is external or load-bearing) and its quantities (length, area, volume). That is why an IFC viewer lets you review a project without installing the software it was modelled in.
The most common versions are IFC2x3 and IFC4. IFC4.3 adds linear infrastructure (roads, rail, bridges). This viewer opens all three, although in IFC4.3 some geometry specific to linear works, such as elements placed along an alignment, may not display completely.
IFC viewer FAQ
Is the IFC viewer free?
Yes. It is free, requires no sign-up and has no limit on uses or models. VisionHub publishes it as an open tool for people working with BIM on site.
Is my IFC file uploaded to a server?
No. The file is read and processed in your browser with WebAssembly. It is not sent to VisionHub or third parties, not stored, and is gone when you close the tab.
Which IFC versions does it open?
IFC2x3, IFC4 and IFC4.3. In IFC4.3, some geometry specific to linear works may not display completely. The engine is web-ifc, the open-source library by That Open Company for reading IFC in the browser.
Does it work on mobile?
Yes, in any modern browser with WebGL (Chrome, Safari, Firefox, Edge). With no server involved, the limit is device memory: use small models on mobile.
Can I see element properties?
Yes. Clicking an element shows its IFC type, name, GlobalId, property sets and quantities (areas, volumes, lengths) exactly as stored in the file.
How is this different from the VisionHub BIM module?
The viewer opens and explores an IFC. The VisionHub BIM module also overlays the model on the site camera image from any day, so design can be compared with what was built. It adds distance, area, height and volume measurements, 2D drawings anchored to each storey, point clouds and several models in the same scene.
