Background

In OpenPlant Modeler, sometimes it could be the modeler's choice or as per project-specific requirement it has been envisioned to get some piping's component for instance a Valve to a different level. A modification in ‘Named Expression’ should require for changing the Component level as per Valve Name and Service Name used. For example PIPELINE.NAME-SERVICE_VALVE_SMALL  OR PIPELINE.NAME-SERVICE_VALVE_BIG as per Valve size selected by the user. See the exercise below where similar content has been described with Valve Size > 80 & with Valve Size <= 80. By default, if we hover on the valves, following are the observations respectively

valve size <= 80


valve size  >  80

Steps to Accomplish

1. Launch OpenPlant Modeler CONNECT Edition.
   
   
   
   
2. For the desired workspace, open the OPModeler.dgnlib as shown
   
   
   
   
3. Change the workflow to the Admin from the top left corner as shown
   
   
   
   
4. From Home > Collections, open Element Templates as shown
   
   
   
   
5. Expand piping node, right-click & create new template group as shown
   
   
   
   
6. Enter the desired name, let’s take VALVE_SMALL for the created template group as shown
   
   
   
   
7. Right-click to the newly created template group (VALVE_SMALL) & create new template as Model & select the color as shown below
   
   
   
   
8. Similarly, by repeating step-5 create one more template group as VALVE_BIG. Right-click to the newly created template group (VALVE_BIG) & create new template as Model & select the color as shown below
   
   
   
   
9. From utilities, update the templates as shown
   
   
   
   
10. From Home > Environment, open Named Expressions, refer image below
    
    
    
    
11. Scroll to down, search for OP_SYMBOLOGY_PIPING & paste the expression mentioned below & save.
    
    Expression :- "BY_LEVEL_AND_TEMPLATE:" & PIPELINE.NAME & IIF((OPITEM.IsOfClass( "VALVE", "OpenPlant_3D" ) AND OPITEM.NOMINAL_DIAMETER <= 80),"-"& PIPELINE.SERVICE_NAME & "_VALVE_SMALL:",
    IIF((OPITEM.IsOfClass( "VALVE", "OpenPlant_3D" ) AND OPITEM.NOMINAL_DIAMETER > 80), "-"& PIPELINE.SERVICE_NAME & "_VALVE_BIG:",":") ) & "OpenPlant\Piping\" &IIF ((OPITEM.IsOfClass( "VALVE", "OpenPlant_3D" ) AND OPITEM.NOMINAL_DIAMETER <= 80), "VALVE_SMALL:",
    IIF ((OPITEM.IsOfClass( "VALVE", "OpenPlant_3D" ) AND OPITEM.NOMINAL_DIAMETER > 80), "VALVE_BIG:","Default:" ) ) & "Model"
    
    
    
    
12. Launch OpenPlant Modeler again & verify results. See images below
    
    For valve size <= 80
    
    
    For valve size > 80
    
    
    
    Notice that service & size tag is added to the level.
