# IFC 4.3 Support

IFC 4.3 is the version of the IFC schema that offers extended support for Infrastructure categories, like Roads, Rails or Bridges (read more about [IFC Schema versions](https://autodesk.ifc-manual.com/understanding-ifc/ifc-schema-versions)).

Revit 2023.1 or higher offers an *experimental* IFC 4.3 support with a basic implementation of the current schema version. Following workflows are supported:

* IFC LINK: IFC4.3 is automatically recognized when linking (Note: Opening IFC 4.3 Files in Revit is NOT supported)
* IFC EXPORT: ”Experimental” (limited implementation for testing purposes)

As soon as IFC 4.3 has been finalized and released as ISO standard, the implementation of the new schema will be continued.&#x20;
