Use existing geometry in a linked IFC model as a reference for dimensions, alignment, snapping, and hosting of some face-based families in a Revit model. When you link an IFC file, its elements are assigned to a default phase, further integrating open standards into Revit. Use many IFC-based elements to define room boundaries when creating rooms in the host model.
Note: Before using IFC Import, Link, or Export, go to Autodesk Exchange Apps for Autodesk Revit and download the latest edition of IFC for Revit.
