What is a IFC file?
IFC is the open BIM standard describing building models — geometry plus rich metadata for architecture and construction. The viewer loads the model with web-ifc (WebAssembly) and renders the 3D building you can orbit and zoom. The .IFC extension identifies a Industry Foundation Classes file, which is served with the application/x-step media type. You can open it here instantly — drop the file into the box above and it renders in your browser. Nothing is uploaded.
Besides this free online viewer, you can open IFC (BIM) files in desktop apps such as Autodesk Revit, ArchiCAD, BIMvision — but here all you need is a web browser.
