Story View and Hierarchy Navigation

The 3D viewer organizes building data by story, room, and building element. Use the story selector, breadcrumbs, navigation lists, and the right-side details panel to move through that structure.

Building hierarchy structure

Section titled “Building hierarchy structure”

The viewer uses a four-level hierarchy:

No Selection (Default)
└── Story (Building Level/Floor)
    └── Room (Space)
        └── Building Element (Wall, Floor, Ceiling, etc.)

Each level provides progressively more detailed control over building elements.

Section titled “Navigation and details panel”

The viewer uses top controls and a right-side details panel instead of an expandable left tree.
