# User Interface

The [user interface](https://docs.phoenixlidar.com/lidarmill-desktop/user-interface) in SpatialExplorer is divided into four sections: left, middle, right, and bottom:

* The **left** section is the Project window which displays the different types of layers available along with numerous tools. 
* The **main** display area in this middle is where the LiDAR point-cloud data is visually generated. 
* The **right** section displays numerous system parameters and options for configuring the main display area. 
* The **bottom** section is a log window where messages/errors are presented to the user. 
* Important messages and errors will be printed with a yellow or red background color, respectively. 
* The various windows can be dragged to different areas of the screen or closed completely to maximize the main viewing area. 
* They can be reopened by navigating to the [Windows tab](https://docs.phoenixlidar.com/lidarmill-desktop/user-interface/windows).
