Examine reference model hierarchy
You can view the reference model hierarchy and check the hierarchy level of different objects. You can also add user-defined attributes to the reference model objects. The added attributes can be used for filtering, for example. Additionally, you can view the native reference object attributes and properties.
Below is an example of a reference model. When you want to scroll the hierarchy, the Select assemblies selection switch or the Select objects in assemblies selection switch must be active. The 0 level IfcProject in the example is the upmost level.
In the image below you can see one of the reference objects on the third level, IfcBuildingStorey, of the same reference model.
As you can see, the level 4, Ifcwall, shows an individual part. In this case, it is a wall.
In the example below, one of the reference objects on the lowest level has been inquired.
