To use an IFC model as a reference for additional design work, link the IFC file to a Revit model.
- (Optional) Before linking an IFC file, click File tab
Open
(IFC Options) and use the Import IFC Options dialog to do the following:
- Select a default Revit template to use for IFC files.
- Load an IFC class mapping file or manually assign Revit categories to IFC classes and types.
- Make sure the IFC file contains the geometric data needed for the
Revit capability that you plan to use. For more information, see
About Imported Geometry.
Note: In Revit 2024.1 and newer, Link IFC uses a new link processor by default. The processor offers more advanced geometric fidelity and stability, but may reduce performance. Change the Revit.ini file to use the legacy IFC link framework. See: Import IFC Settings.
Note: If a default template is not selected, the first template listed under File Locations in Revit Options will be used. - Open the Revit model.
- Click Insert tabLink panel
(Link IFC).
- In the Open IFC File dialog, navigate to the IFC file, select it.
- For Positioning, specify the desired option.
In most cases, you should select Auto - Origin to Origin.
If the current model uses shared coordinates, select Auto - By Shared Coordinates. See Shared positioning.
- Click Open.
In most cases, you should select Auto - Origin to Origin.
The software uses the IFC file to create the following files:- an intermediate Revit model named <ifc_file>.ifc.RVT
- a log file named <ifc_file>.ifc.log.html
- a shared parameters file named <ifc_file>.ifc.sharedparameters.txt
The software then links the intermediate IFC-based model to the host model.
