Prerequisites

Overview
--------

The Paradata Manager shows all qualia for a selected SU. Alt+F selects a 3D object and highlights it in the Stratigraphic Manager simultaneously. The experimental graph visualisation tool draws the full knowledge graph, enabling bidirectional navigation between graph nodes and 3D objects.

Key Concepts
------------

- Alt+F: select a 3D object and locate it in the Stratigraphic Manager simultaneously.
- Paradata Manager: lists all qualia, sources, and interpretations for the selected SU.
- Graph visualisation: draws the full EM as an interactive diagram inside Blender.
- Bidirectional: click a graph node to select the corresponding 3D object and vice versa.

Try It Yourself
---------------

Select three different objects in the Great Temple scene using Alt+F and compare their paradata in the Paradata Manager.
