BIMViewer
BIMViewer is a browser-based viewer and coordination workbench for inspecting and working with building information models in IFC formats.
What BIMViewer is
BIMViewer is a browser-based viewer and coordination workbench for inspecting and working with building information models in IFC formats. It can combine multiple discipline models in one scene while preserving each model’s separate spatial tree. Inspection tools show element attributes, property sets, and quantities; users can isolate or hide elements, cut section planes, measure distances, and export PNG snapshots. It reads IFC2x3, IFC4, IFC4x3, and zipped .ifczip files, but does not open native Revit .rvt files directly. The workbench also includes IFC Validator, IFC Compressor, IFC Merge, IFC to Excel, IFC Properties, and IFC to glTF. Models are parsed and rendered locally in the browser using WebAssembly rather than uploaded, and the session copy ends when the tab is closed. A current browser with WebAssembly and WebGL is required; the service works on desktop or mobile without a plugin, desktop app, or account. The free plan includes the viewer and tools without file or frequency limits. Visual coordination is supported, but automated rule-based clash tests are not.
Good
- Free access to the viewer and workbench tools.
- Combines multiple IFC models in one scene.
- Measures distances and exports PNG snapshots.
- Processes models locally in the browser.
Watch out
- Does not open native Revit .rvt files directly.
- Requires a current browser with WebAssembly and WebGL.
- Does not run automated rule-based clash tests.
Who it suits
BIMViewer suits contractors, clients, engineers, site managers, and subcontractors who need to inspect IFC deliverables without authoring software licenses. It can also suit teams coordinating multiple discipline models in a browser.
Verdict
BIMViewer offers browser-based IFC inspection, coordination, and related file tools at no charge. Confirm that the model is in a supported IFC format and that visual coordination meets your needs.
