In [3D point classification](docId\:PjhfySmX9PnQW12XyNIOR) tasks, the **Locate unlabelled areas** toolbar button helps you find points you have not classified yet. It hides all labelled areas in the point cloud, so only the unclassified points remain visible — making missed areas easy to spot before you submit.

The button's tooltip also tells you how much is left: *"There are  unclassified points."*

## How to use it

:::hint{type="info"}
The same name is used for a different tool in 2D segmentation tasks, where it highlights unlabelled gaps in the image in red. See [Locate unlabelled areas in 2D](docId\:W0s6Hgyac9HrzcEZP1sPy).
