The Blueprint Panel shows the hierarchical structure of your current blueprint and provides controls for modifying the Viewer layout.
For a complete understanding of blueprints, see Blueprints. For hands-on tutorials on configuring the Viewer, see Configure the Viewer.

Reset to Default Blueprint: Returns to your programmatically specified blueprint (sent from code via rr.send_blueprint()) or a loaded blueprint file (.rbl). This becomes the "default" whenever you send or load a blueprint.
Reset to Heuristic Blueprint: Generates a new blueprint automatically based on your current data. The Viewer analyzes your logged data and creates an appropriate layout using built-in heuristics.
If no default blueprint has been set, the reset button uses the heuristic blueprint. See Reset Behavior for more details.
The "+" button allows you to add new views or containers.
The blueprint panel displays a tree view showing:
Hovering over any item reveals controls for:
Right-click any item for a context menu with additional operations. See Configure the Viewer for details on all interactive operations.
Entities shown in the blueprint panel refer to their data blueprints—the entity plus its associated blueprint settings. Changes made here apply only to the specific view where the entity appears.
When entities are added to a view (manually or automatically), hierarchical groupings are created based on Entity Paths. These groups help organize large views and enable hierarchical manipulation of blueprints. Groups are independent of logged data and exist purely for blueprint organization.
To add or re-add an entity to a view:
See Entity Queries for information on how view content is determined.
