Note that I'm discussing the GUID used in IFC, not MicroStation's element IDs.
If the updated IFC exporter stabilises the IFC GUID allocation, the implication suggests that the IFC GUID is stored in the DGN file in order to allow its persistence on subsequent export. If that is the case we have what we need to round-trip the IFC GUID between third-party apps. and ORD. Can you confirm that to be the situation?
I saw this same discussion in the OpenBuildings forum and was wondering the same thing!
