# Section Details panel

The Section Details panel provides a tabular overview of all sections in the current tunnel and displays properties for the active section. It is located in the right-side panel of the application window.

## Section Details tab

The **Section Details** tab contains a grid listing every section in the tunnel with the following columns:

| Column | Description |
|---|---|
| **Station** | Chainage along the alignment |
| **Name** | Section identifier |
| **Bearing** | Surveying bearing at the station |
| **Template** | Name of the assigned design template |
| **Elevation** | Alignment elevation at the station |
| **Grade** | Longitudinal gradient in percent |
| **Offsets** | Horizontal and vertical offset from the alignment axis |
| **Superelevation** | Cross-fall value at the station |

### Navigating with the grid

Double-click any row in the grid to navigate directly to that section. The Sections canvas tab updates to display the selected section, and the alignment canvas highlights the corresponding station.

```{tip}
The Section Details grid is the fastest way to jump to a specific section when you know its station or name. Combine it with the Prev/Next ribbon buttons for sequential review.
```

## Properties tab

The **Properties** tab shows the CAD object inspector for the currently selected entity on the canvas. When an entity is selected (such as a section line or template line), its geometric and display properties appear here for review.

```{note}
The Properties tab reflects the canvas selection. If no entity is selected, the tab is empty. Click on a line or point on the Sections canvas to populate it.
```

## Status bar

The status bar at the bottom of the application window shows the cursor coordinates in the local section coordinate system:

- **X** -- horizontal offset from the alignment axis (positive = right, negative = left)
- **Y** -- elevation

```{note}
These coordinates match the section's local system, not world coordinates. The offset convention follows TunnelCAD's standard: positive offsets are to the right of the alignment axis, negative offsets are to the left.
