I wonder how the ODA IFC support will change things around? Right now, all current BIM software already uses one of the toolkits. I don’t see this changing by switching to another toolkit, although when companies are already using ODA DWG libraries, this will make it easier to also support IFC.
E.g. the EDM-toolkit is used both for ARCHICAD and Revit, yet we all know that their IFC files can be structured very differently…
To me, one of the roles buildingSMART plays is precisely the certification process, to ensure consistency and quality between implementations software. Right now, the process seems out of reach for any non-commercial or open-source entity. Yet many solutions depend on toolkits such as IfcOpenShell, XBIM, GeometryGym. I assume ODA might have more means to reach certification, but it is also a non-profit.
The list of certified software is not containing these toolkits, so each vendor implementating IFC using such a toolkit needs to go to certification separately:
