The PredefinedType is defined either via the IfcTypeObject , or if no IfcTypeObject was defined, via the attribute 9 “PredefinedType” of the IfcObject.
Depending on the viewer, the PredefinedType (IfcObject) is not displayed…
For example when opening an IFC file in Solibri the PredefinedType assigned to the IfcObject is not displayed. However, if they are defined via an IfcTypeObject the information is present and visible.
