# Isolate

This feature is available when the user is labelling in the point cloud. It allows users to crop out an area of point cloud to eliminate noise.

## Benefits

* **Enhanced Focus:** Allows annotators to concentrate on a specific area of interest, eliminating distractions from irrelevant regions.
* **Increased Annotation Accuracy:** Provides a clearer view of smaller, detailed areas, aiding precise annotation.
* **Improved Performance:** Reduces computational load and improves tool responsiveness by limiting the data being processed and displayed.

## Steps to use Isolate

1. Enable the 'Isolate' toggle from the [header](https://docs.imerit-prod.io/annotation-tool/key-features/pages/t1P8d2reKe3nZWAkN2Kh#id-1.-header) of the [annotation tool](/annotation-tool.md).
2. On toggling it ON, the user can make multiple clicks on the point cloud to draw a boundary and right click to apply Isolation.&#x20;
   * Similarly, move to Annotate Image mode and [project points on the image](/annotation-tool/key-features/project-points-on-image.md). Select the 'Isolate' toggle, and cut out a portion of the point cloud with the help of the image.
3. All the points falling out of the defined boundary will be hidden from view. Users can now start labelling objects in the visible patch without background disturbance.&#x20;
   1. The user can navigate to the next frame and observe isolate is applied, therefore not have to lose context.
   2. The user can also merge the point clouds and understand the scene after removing the unnecessary points.
