Deleting an entity deletes the selected entity and any relationships between it and other entities.
To delete an entity, select its shape on the diagram and:
You will be asked to confirm the entity's deletion.
If the selected entity includes elements as the result of a relationship with another entity, those elements are detached from the selected entity. Similarly, if another entity contains elements from the selected entity as the result of a relationship, those elements are detached from the entity.
Any elements in a deleted Data, Conceptual or Variant entity become available as Unattached Elements for later use if required (refer to 3.11 Maintaining Unattached Elements).
In addition, the build statuses of the selected Data, Conceptual or Variant entity and any related entities are reset appropriately if they have been previously built.
