# 3D View

> Analyze terrain slopes, table slope constraints, and post heights for solar array layouts

The 3D View provides tools for analyzing terrain and racking placement within your map-based power plant design. This interface enables terrain slope analysis, table slope constraint identification, and post height calculations.

<Warning>
  **Legacy Feature:** The 3D View is a legacy feature set that has been superseded by **Terrain Pro**. For advanced terrain analysis and optimization, consider using Terrain Pro.

## Overview

The 3D View interface is organized into the following sections:

1. **Height Analysis Table** — Displays a breakdown of post heights across the layout with counts and percentages.
2. **Terrain Analysis Panel** — Configure and execute terrain slope constraints and post height analysis.
3. **Layers** — Toggle visibility of wireframe and DC layer overlays.
4. **Export Model** — Export the 3D model for external use.

## User Inputs

### Height Analysis Table

This table displays the distribution of post heights across the layout after executing a post height analysis.

    </tr>
  </thead>

  <tbody>
    <tr>
      <td>**Height**</td>
      <td>Display</td>
      <td>Height range categories for post heights (e.g., ≤1.5m, 2m, 2.5m, 3m, 3.5m, >3.5m).</td>
    </tr>

    <tr>
      <td>**Count**</td>
      <td>Display</td>
      <td>The number of posts falling within each height category.</td>
    </tr>

</table>

### Terrain Analysis Panel

Configure terrain slope constraints and post height analysis parameters.
