We've just started working with consultants who use ArchiCAD and send us IFC files.

So far, I understand that the workflow is as such:
Open IFC file
Save as Revit file
Import (currently using Origin to Origin)

When I tried updating the IFC link (translated to Revit) with a newer model, the building came in rotated and very far from it's location.

Have any of you dealt with IFC collaboration before and figured out the proper steps for importing and updating while keeping the coordinated intact? If so, please share the knowledge.
