# 3D Building Viewer

> Manipulate the selected building in 3D, toggle map views, and snapshot your results.

The 3D Building Viewer lets you move the selected design in place on its site and see how it responds to site constraints.

## Viewer toolbar

The viewer toolbar sits in the **top-left corner** and centralizes the key design actions:

* **Undo / redo** recent changes
* **Mirror building** across a chosen axis
* **Edit site boundaries and setbacks** without leaving the viewer
* **Create a snapshot** of the current view for reports or exports

## Viewer controls

Navigation controls live in the **bottom-right corner** of the viewer:

* **Toggle** between Street View and 3D Satellite view
* **Re-center** your site in the viewer
* **North arrow** to orient your bearings
* **Zoom** in and out

## Constraint warnings

Property constraints turn red when violated — you see issues the moment they happen as you rotate or reposition the building.
