Delete by class
Not Lite
Delete by class action performs about the same process as options of the Delete command. The action deletes points from the block binary files. You can select a certain class and specify the area from which to delete points.
For LAS 1.4 files, you can specify that the withheld bit is set instead of removing points from the file.
