IfcEntity for cantilever slab connection

Hi there

I’ve got a question about thermally-insulated cantilever slab connections (I hope these elements will be called like this). In your opinion as what should they be classified these most suitable:

  • IfcSlab (because the element is a part of the slab)
  • IfcBeam (because of similar geometry dimensions)
  • IfcCovering (because of the thermal insulation function)
  • IfcWall (because of the tool used to model it in CAD)
  • IfcBuildingElementProxy (because in fact it doesn’t fit into any group above)

Thank you for your answers!
