I have an IFC model that I've created with Revit and checked with Solibri. When I bring the model into Archicad, it sends all the doors 400' feet or so into the air. It will also improperly trim walls to roofs and window openings and leave strange wall cuts.
I've tried adjusting all of the elevation settings and project 0 to no avail. It seems to be a problem with the sill height in connection to it's referenced story which can only be corrected by individually editing each door individually, which is useless for interoperability.
I have the latest IFC update and have checked that the model is perfect in solibri.
