Currently, the Engineering data contained in an IFC file, does not group the data structures of different referenced DGN files. There is no Filename or Model property (such as Model Name, Description, Logical Name) that is present in the IFC file.

Hence, there is no easy way to navigate a large IFC Export. For example, if user wants to turn off the view of an entire model, or a collection of model, this is not possible, without manually selecting each item of the model and hiding those objects.
