What kind of group is created for tags placed on items in a model group?

Tags placed on items in a model group are organized within an attached detail group. This type of grouping allows tags to remain associated with the specific elements they annotate, enhancing the clarity and organization within a Revit project. By using attached detail groups, users can ensure that tags move with the model elements, maintaining their relevance and visibility, especially when adjustments are made to the model.

Additionally, attached detail groups work effectively with various view settings, enabling users to manage how tags appear in different view types. This functionality is crucial in large projects where elements may change or be remodeled, ensuring that the informational integrity of the tags remains intact.

The other group types listed do not specifically cater to the management of tags in the way that attached detail groups do, focusing instead on other aspects of model elements or detailing. In contrast, the attached detail group is specifically designed to handle annotations like tags while remaining connected to the geometry they annotate, providing a streamlined approach to documentation in a Revit project.
