If a selection is present, **Classify By Class** will only change the class of selected points. This can be useful, for instance, when assigning a [**Cloud Query Tool**](https://docs.phoenixlidar.com/spatialexplorer-8-and-9/user-interface/data-visualization#cloud-script-tool) selection to a class.&#x20;
