Why are some components not found, while they are in my Archicad Model?

When exporting an IFC file from Archicad, a user can set an option to export a composite wall or slab as separate ‘building element parts’. This feature creates new subparts in the IFC file only, which are in reality, not present in the Archicad source model. When issues refer to these subparts from other applications, the BCF Manager can’t select or show them as they do not exist in the Archicad source model. Always make sure that issues only refer to the main wall or slab components and not to their subparts.
