Story View and Hierarchy Navigation

Story View and Hierarchy Navigation

Section titled “Story View and Hierarchy Navigation”

The 3D viewer organizes building data in a structured hierarchy displayed in the left panel.

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.

Left panel

  • Highlight room in 3D view

Room-level operations

Section titled “Room-level operations”

When a room is selected:

  • Edit room properties (name, type, area)
  • View boundary elements (walls, floors, ceilings)
  • Calculate room metrics (volume, surface area, heat loss)
  • Assign materials to all room elements

Building element level

Section titled “Building element level”

  • Element type icons: Wall, floor, roof, window, door
  • Element ID/Name: Unique identifier or description
  • Area: Surface area in square meters
  • Material: Assigned construction type

Selecting an element

Section titled “Selecting an element”

Click on an element to:

  • Select element as current scope
  • Show element properties in right panel
  • Highlight element in 3D view with color
  • Display edge dimensions as labels in 3D

Element-level operations

Section titled “Element-level operations”

When an element is selected:

  • Edit element properties (area, orientation, inclination)
  • Assign materials and thermal properties
  • View/edit B-factor (thermal reduction factor)
  • Split element into multiple parts
  • Add openings (windows, doors)
  • Edit geometry (move points, reshape)
  • View dimensions on edges

Synchronization: hierarchy ↔ 3D view

Section titled “Synchronization: hierarchy ↔ 3D view”

The hierarchy panel and 3D canvas are bidirectionally linked:

Selection from hierarchy → 3D

Section titled “Selection from hierarchy → 3D”

When you click an item in the hierarchy panel:

  1. 3D view focuses on that element
  2. Element highlights in 3D with color
  3. Camera may reposition to show element
  4. Properties panel updates with element details

Selection from 3D → hierarchy

Section titled “Selection from 3D → hierarchy”

When you click a mesh in the 3D view:

  1. Hierarchy panel highlights the corresponding item
  2. Parent tree expands to show selection
  3. Properties panel displays element info

Layer controls

Section titled “Layer controls”

Control visibility of different types of content in the 3D view.

Accessing layer controls

Section titled “Accessing layer controls”

Location: Bottom-left corner of the 3D canvas

Click the layers button (stacked layers icon) to open the layer controls menu.

Available layer categories

Section titled “Available layer categories”

The layer controls are organized into three categories:

Notes

Section titled “Notes”

Toggle visibility for note types:

  • Condition - Condition assessment notes
  • Electric - Electrical installation notes
  • Building element - Building element notes
  • Material - Material-related notes
  • Other - Other notes
  • Technical installation - Technical installation notes

Building elements

Section titled “Building elements”

Toggle visibility for building elements:

  • Ceilings - Show/hide ceiling elements in 3D view

Other

Section titled “Other”

Toggle visibility for additional information:

  • Projections - Show/hide projected measurements
  • Labels - Show/hide measurement labels
  • Measured areas - Show/hide area measurements

Using layer controls

Section titled “Using layer controls”

To toggle a layer:

  1. Click the layers button in bottom-left corner of 3D canvas
  2. Check or uncheck the layer checkbox
  3. Changes apply immediately to the 3D view

Layer behavior

Section titled “Layer behavior”

When a layer is hidden:

  • Elements are not rendered in 3D canvas
  • Elements are still visible in hierarchy panel
  • Can still be selected from hierarchy panel
  • Properties can still be edited

Coordinate axes and orientation

Section titled “Coordinate axes and orientation”

The viewer displays coordinate axes to help with spatial orientation:

Axis display

Section titled “Axis display”

Located in the 3D canvas:

  • X/Y/Z Axes: Visual gizmo showing coordinate system orientation
  • Spatial Reference: Helps maintain awareness of 3D space layout

Distance labels and measurements

Section titled “Distance labels and measurements”

Edge labels

Section titled “Edge labels”

In certain contexts, edge dimensions may display:

  • Length in Meters: Shows measurements for specific elements
  • Label Position: Positioned along edge in 3D space
  • Scale Adaptive: Labels remain readable at any zoom level
  • Contextual Display: Shown selectively based on element type and selection

Ruler tool

Section titled “Ruler tool”

Use the Ruler tool for custom measurements:

  1. Select Ruler from tool palette
  2. Click first point in 3D view
  3. Click second point to complete measurement
  4. Distance label appears between points
  5. Measurement persists until tool is changed or canceled

Limitations

Section titled “Limitations”

Based on the actual implementation:

  • No drag-and-drop reordering: Cannot move elements between rooms/stories
  • No multi-selection: Select one item at a time (use parent level for bulk scope)
  • Fixed hierarchy levels: Cannot add custom hierarchy levels
  • No custom grouping: Grouping limited to story → room → element structure

Keyboard shortcuts

Section titled “Keyboard shortcuts”

The current implementation does not include keyboard shortcuts for hierarchy navigation. Navigation is performed via mouse clicks in the panel or 3D view.
