Free BIM viewer
Review BIM models without a BIM licence

Got a BIM model from an architect or engineer but no Revit or Archicad? Open it here, walk around it, filter it by element and level, check what each element is and measure it.

The model opens on your own computer and is never uploaded, so it is safe for unpublished projects.

Free. IFC and other 3D files stay on your computer: they open in this browser tab and are never uploaded. Revit and SolidWorks files are the exception: they are sent to Autodesk's conversion service in the EU and deleted within 24 hours.

File will not convert, or the model needs cleaning up? Our team fixes and converts it for you. Send us the file and we reply with a fixed price. Send the file

How it works

How to view a BIM model online

3 steps, and the model never leaves your computer.

1. Get the model as IFC

Ask the architect or engineer for an IFC file, or export one yourself (the steps are below). IFC is the open BIM format that every BIM program can save.

2. Open it and look around

Drop the file on the viewer. Orbit, pan and zoom, pick a level to see one floor, and untick element types to look behind walls, roofs or ceilings.

3. Check and measure

Click any element to see what it is, its level and its properties. Use Measure for heights, widths and distances, straight from the model.

Who it is for

A BIM viewer for people who do not work in BIM

For everyone who receives a model and needs to look inside it.

Developers and clients

See the design your architect is working on in 3D, floor by floor, without installing anything. Check room heights, window sizes and what is actually modelled before you sign off a stage.

Contractors and quantity surveyors

Count elements by type, check what is load-bearing or fire rated, and measure spans and heights. The element list shows how many walls, slabs, doors and windows are in the model.

Engineers and consultants

Open the architect's model next to your own work, look at one level at a time, and read the property sets each element was exported with, such as Pset_WallCommon.

Facility and property managers

Look up an element's name, type and properties in the handover model, without a BIM licence on every desk.

How to get IFC from Revit, Archicad, Navisworks and other BIM programs

Native BIM files cannot be opened in a browser. Their IFC export can.

Revit

File > Export > IFC. IFC 2x3 Coordination View 2.0 or IFC4 Reference View both open here. Drop a .rvt file and it is converted to IFC for you first.

Archicad

File > Save As, then choose IFC as the file type. A .pln file cannot be opened outside Archicad, so ask for the IFC.

Navisworks and Tekla

Navisworks .nwd files are not IFC: ask for the IFC export of the original models. Tekla Structures: File > Export > IFC.

Vectorworks, Allplan and others

Vectorworks: File > Export > Export IFC Project. Allplan, Bentley, BricsCAD BIM and FreeCAD all have an IFC export in their File menu.

From BIM model to images

What we make from BIM models

Developers and architects send us their BIM models to be turned into images and films that sell, win planning and win competitions. See our exterior rendering and interior rendering services.

BIM viewer FAQ

Questions about viewing BIM models

File formats, licences, large models and privacy.

Ask us a question
Do I need Revit or Archicad to use this BIM viewer?
No. It runs in your browser with nothing to install and no licence. The model has to be an IFC file, which every BIM program can export, so ask whoever sent you the model for the IFC version.
Can it open .rvt, .pln or .nwd files?
Revit files, yes: drop the .rvt and it is converted to IFC by Autodesk's own conversion service, then opens here (or use the Revit to IFC converter to keep the IFC file). Archicad and Navisworks files use closed formats no free browser tool can read, so export IFC from those programs.
Is this the same as the IFC viewer?
It uses the same engine. The IFC viewer page explains the IFC format and its versions; this page is about reviewing a model when you do not work in BIM yourself. Both open the same files.
Is my model uploaded?
No. The model is opened in this browser tab on your own computer and is never sent to us or anyone else, so it is safe to use for unpublished or confidential projects.
How large a model can it open?
Your own computer does the work, so the limit is its memory. Models of 100 MB and more usually open on a normal laptop but take longer. For a very large project, ask for the IFC of one building or one discipline.
Can I add comments or check clashes?
No. This is a viewer: it shows, filters and measures the model and can save a copy as GLB, OBJ, STL or STEP. Clash detection and issue tracking belong in coordination software such as Solibri or Navisworks.
