Hello Odacfidi,
Into Archicad we use translators about IFC import and export.
Before checking these translators you have to know how this IFC was exported from Revit to be able to select the right parameters.
First of all you can read this IFC with a free IFC viewer to understand what you are able to import into Archicad.
Finaly you are able to import IFC into Archicad by opening it by the menu File/Open or import IFC by external an dynamic link but always with a translator.
