To set Component symbology with Valve by Size & Service i.e. PIPELINE.NAME-Service_Valve_Type in OpenPlant Modeler using Named Expression.
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’ is required for changing the components symbology by pipeline name which can be found in the ‘Utilities’ Menu and to customize ‘Element Template’ to define the name and hence color under ‘Element’ option.
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_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"
