请教各位大佬，specical要加shielding，要怎么操作？

1、editSelect -layer {ME3 ME4} -use POWER -wires_only 0 -type Special -net VREF
2、createShield


#WARNING (NRDB-877) NET VREF is completely routed with special WIRE and will not be modified. The "-skip_routing" attribute for the NET is set to true. To modify the NET or allow modification of this NET set NET attribute with "setAttribute -net netName -skip_routing false".

请教各位大佬，这种线要加shielding，要怎么操作才行
