IFC: Model contexts and subcontexts

in General

Recently learned about the different contexts in IFC after stumbling across an unexpected issue on BonsaiBIM with the Duplex House model which I posted on the IfcOpenShell's GitHub issues page here: https://github.com/IfcOpenShell/IfcOpenShell/issues/5824

Do most BIM Authoring tools (e.g. Revit, Archicad) allow for exporting these contexts? Are there any resources on this topic?

    Revit

    • I haven't found any documentation for this
    • it exports detail elements as plan representation and 3d as model representation
    • I think this behaviour is hardcoded and there's no way to add for example a bounding box

    Archicad

    • I didn't look for documentation
    • archicad gdl has very similar concepts, so 2d script exports to plan and 3d script to model
    • I also think this is hardcoded, but there might be a way to export something more

    @Moult gave a nice explanation here, once.
