Pointcloud Operator dialog box - PURGE Operator
From the COP command referenced by this operator, the PURGE operation removes all data points that do not belong to this operator. The PURGE operation is irreversible and affects all other operator commands that refer to the same COP container, so use the operation with caution.
To apply the PURGE operation to a pointcloud, click
Purge Pointcloud (
)
on the Pointcloud toolbar, or select Operation
| Pointcloud | Purge.
Clicking Create inserts a COP/OPER,PURGE command into the Edit window like the following examples:
COPPURGE1=COP/OPER,PURGE,SIZE=0
REF,COPSECTION1,,
Once you apply this command to a COP, there is no way to restore the COP data that was removed. You cannot click Undo to restore the data.
