This command removes the extended entity data of pit/site names from the selected polylines. For example if you are done calculating for an area, you can use this command to clear the pit names from the polylines in the old area so that these polylines are not picked up as pits anymore by routines such as Surface Mine Reserves and the Timing Routines.
Select polylines to remove pit names from.
Select objects: pick the polylines
