Revit MEP provides Industry Foundation Classes (IFC) import based on the latest International Alliance for Interoperability (IAI) IFC 2x3 data exchange standard. (If you import a file that uses an earlier standard [IFC 2x or 2x2], Revit MEP supports the format and imports it properly.)
To import an IFC file:
- Click File menu => Import/Link => IFC.
- In the Import dialog, navigate to the IFC file to import.
- Select the IFC file, and click Open.
