What is an IFC file?
An .IFC file is an Industry Foundation Classes File. It contains a 3D model and data for a building or structure. BuildingSMART created this format to make it easy to share Building Information Model (BIM) data between different software programs. Architecture, engineering, and construction professionals use .IFC files to share 3D designs without losing important physical and logical data.
How to open IFC files?
You can open an .IFC file using professional 3D CAD and BIM software. Programs like Revit, Archicad, and BlenderBIM fully support this format. Developers can also read and edit .IFC files programmatically using libraries like IfcOpenShell.
If you do not have complex CAD software installed, viewer.online/ifc analyzes .IFC files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Best practices and troubleshooting
Large .IFC files can take a long time to load and may slow down your computer. If you only need to inspect the geometry visually, use a dedicated, lightweight viewer like BIMvision. If you need to use the 3D model in a standard modeling program, you should convert the file. We recommend using convert.guru to easily convert your .IFC files into .OBJ, .STEP, or .DAE formats for broader compatibility.
Summary
viewer.online/ifc directly opens and previews .IFC files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
