Delete by line
Not Lite
Delete by line action performs about the same process as the By line option of the Delete command. The action deletes points from the block binary files. You can define a certain line number 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 deleting points.
