To import an IFC file into ARCHICAD, navigate to the File > Open. (If you already have a project running, check the option “launch a new instance of ARCHICAD”).
Prior to importing the IFC file, you must decide how to import the geometry/attributes of the IFC file. This is governed by the IFC Translator – Import options.
Tip: The benefit of using File > Open over Merge is that you can first check the story setup of the IFC Model.
