//  Description:
//
//      This is the interface for display smoothness, so that both
//      nurbs and subdivision surfaces smoothness can be changed 
//      using the 1,2,3 keys.
//
//      First, pass everything off to nurbs displaySmoothness
//
//      If subdiv slice exists,
//          Gets a list of subdivs and passes them off to 
//          subdivDisplaySmoothness
//

		$selList = `ls -hl`;
		$len = size($selList) ;
	}
	if ($len == 0) {
	  return 0;
	}
	  
	// 
	// Set nurbs display smoothness
