7. Add 'Creation Attribute' and click OK.
   
   
   
   
8. Now go to ASSOCIATED_ITEM_LIST_FOR_PIPING_NETWORK_SYSTEM class and switch to properties tab.
   
   
   
   
9. Click "Add" button and name the property as 'PLANT_AREA'.
   
   
   
   
10. Click 'Custom Attributes' button and select 'Add/Remove' option.
