The BimClassify command classifies an entity as a Building Element and get a name and an internal GUID (= globally unique identifier).
A BIM model file can contain one site and multiple buildings. A building contains multiple stories.
Entities that are classified as a Building element have a Building and a Story property.

To examine the model in the Structure panel
The Structure panel allows to examine the BIM model. By default, the structure of building elements is organized by spatial containment. Building elements are grouped first by Building, then by Story, then by BIM type, then by composition. This organization can be fully configured: any property, including all ifc properties, can be used as a grouping or sorting rule.
