To Assign Level by Equipment Tag in OpenPlant Modeler using Named Expressions.

Background 

OpenPlant component symbology is managed in the typical MicroStation fashion. It is controlled through a combination of Named Expressions (used to read attributes and assign the Element Templates accordingly) and Element Templates (where symbology is defined for the elements identified by the Named Expression).

A modification in ‘Named Expression’ should require for changing the Equipment level as per Equipment Name and Tag Number  like TANK-T-21, PUMP-PMP-33, VESSEL-V-19 etc. see below exercise where similar content has been described. 

Steps to Accomplish

  1. Go to File from Main Menu option and open DGN library files (dgnlib). See image below :



  2. Under Utility Menu, Select Named expression and click on OP_SYMBOLOGY_EQUIPMENT. See image below for reference.



  3. Below are the Symbology pasted to copy from here and to get it pasted to its respective Expression’s.  

    OP_SYMBOLOGY_EQUIPMENT:

    "BY_LEVEL_AND_TEMPLATE:" & IIF(OPITEM.IsOfClass("NOZZLE", "OpenPlant_3D"), "Nozzle-"& OPITEM.NAME &":",

     IIF(OPITEM.IsOfClass("TANK", "OpenPlant_3D"), "Tank-"& OPITEM.NAME &":",

         IIF(OPITEM.IsOfClass("PUMP", "OpenPlant_3D"), "Pump-"& OPITEM.NAME &":",

             IIF(OPITEM.IsOfClass("HEAT_EXCHANGER", "OpenPlant_3D"), "Heat_Exchanger-"& OPITEM.NAME &":",

                 IIF(OPITEM.IsOfClass("VESSEL", "OpenPlant_3D"), "Vessel-"& OPITEM.NAME &":",":"))))) & "OpenPlant\Equipment\" &

      IIF( OPITEM.IsOfClass( "NOZZLE", "OpenPlant_3D" ),  "Nozzle:",

         IIF( OPITEM.IsOfClass( "TANK", "OpenPlant_3D" ),  "Tank:",

              IIF( OPITEM.IsOfClass( "PUMP", "OpenPlant_3D" ), "Pump:",

                   IIF( OPITEM.IsOfClass( "HEAT_EXCHANGER", "OpenPlant_3D" ), "HeatExchanger:",

                        IIF( OPITEM.IsOfClass( "VESSEL", "OpenPlant_3D" ), "Vessel:", "Default:" ) ) ) ) ) & "Model"


    Note: Make sure to copy the strings correctly.

  4. Save each Expression which turns blue. Save option will get enabled once you modify the Expressions: See below for reference.



  5. Launch OpenPlant Modeler and Verify results. See images below:

    Equipment Level as ‘Vessel-V-19’



    Equipment Level as ‘Tank-T-21’



    Equipment Level as ‘Pump-PMP-33’



    Equipment Level as ‘Heat_Exchanger-EX-3’
