CUTVOL,<cutnum>,[Xmin],[Xmax],[Ymin],[Ymax],[Zmin],[Zmax]
This command adds elements to the cut data structure defined by the user with the <cutnum> argument by volume. The Volume is defined by the other arguments in the command. The user can leave any or all of the volume boundaries empty. By default any boundary argument left empty will be replaced by the appropriate minimum or maximum for the active model.
