LIDAR point cloud classification

[berkansaritas]

Hello;
I want to classify the LIDAR point cloud yield so that it is only ground points. For this purpose, I want to use the classifications contained in the window I opened with the "Cloud layers" button. I only leave the ground class open, and when I close all other classes, I can only see the points belonging to the ground. When I close the cloud layers window, it reverts back to its previous state and the ground points cannot be distinguished. How can I export only the ground class?

Thank you..

Yes, that's not how the plugin can be used.

You can simply use the 'Edit > Scalar fields > Filter by value' tool, and use the right class value as min and max values.
