# Obstructions, roads, and parcels

Draw site features, detect rooftop obstructions, and check their dimensions.

Source: https://docs.solesca.com/editor/obstructions/

Obstructions keep modules clear of objects and can affect shading. Draw them with the obstruction tools in the editor toolbar.

## Draw an obstruction

The obstruction menu offers shape, rectangle, circle, line, and tree tools.

- Use a polygon for an irregular footprint.
- Use a rectangle or circle for regular rooftop equipment or other simple footprints.
- Use a line for a fence, parapet, or other narrow feature.
- Use a tree for a trunk and canopy.

Follow the selected tool's drawing prompts. Finish a polygon or line with `Enter`, and return to **Cursor** when done.

## Edit dimensions and setbacks

Select an obstruction to open its inspector. Set its type, height, and setback as appropriate. A tree has controls for its trunk and crown.

Move or reshape the object to match the site. Check its height in 3D and its setback in plan view. [Obstruction templates](https://docs.solesca.com/system/other-templates/#obstruction-templates) provide reusable defaults.

On a 3D map, **Match height to 3D** or **Match size to 3D** can provide an estimate. See [3D measurements](https://docs.solesca.com/editor/3d-measurements/).

## Roads and parcels

Use the site-infrastructure tools to draw roads and parcels. A road reserves space in the layout; review its width and setback. A parcel marks the property boundary and does not itself define an array.

Parcels appear in the **Civil** lane. Select them there or on the map to edit them.

## ARGUS on roofs

ARGUS detects rooftop obstructions from imagery.

1. Select a **Flat roof** or **Pitched roof** field.
2. In **ARGUS AI**, click **Detect obstructions**.
3. Review the obstruction template and options in the dialog, then start detection.
4. Review the detected objects, their types, dimensions, and setbacks.
5. Correct missing or inaccurate objects before modeling.

A rerun replaces ARGUS detections on that field and keeps manually drawn obstructions. Detection is a starting point for review, not a confirmation of every object on the roof.

## Sensitivity

**Sensitivity** controls how many detections are included. Increase it to include more possible obstructions, or reduce it to keep fewer. Review the result against the imagery after each change.

Use **Match all heights to 3D** to estimate the heights of the field's detected obstructions, then inspect individual objects as needed.

## Walkways and refinement

Use fire-walkway spacing to reserve access at the distance you specify. Equipment walkways and module-removal controls are described in [Design refinement](https://docs.solesca.com/editor/refinement/).
