Revit 2014 and Earlier

In Revit 2014 and earlier, you cannot import or link an IFC file directly. You must open the IFC file in Revit, save it as a Revit project, then link the Revit project.

To do this, press the “R” button in the top-left corner to open the Revit menu. Expand the Open menu, then select the IFC command. The keyboard shortcut sequence for this is ALT+F, ALT+Y, ALT+I.

Select the IFC file you want to import.

After the IFC file is imported, save it as a Revit file. You can now use this Revit file to check for collisions with other Revit files.

Revit 2015 and Later

In Revit 2015 and later, you can link an IFC file without having to convert it.

Use the Insert->Link IFC command to link the IFC file.
