Replace Component

[jbryant74]

Hi all,
I am having issue with this not working. What am I missing?
I would expect it to replace PHILLIPS7_8 with SLOT7_8

It looks like it runs but nothing gets replaced

This is taken from the example code.

public static void replaceBolts(com.ptc.pfc.pfcAssembly.Assembly assembly)
{
    // Current Creo session
    Session session = null; 
    
    // The base bolt part model
    Solid bolt = null; 
    
    // Family table row used to create the new instance
    FamilyTableRow row = null; 
    
    // The newly created bolt instance
    Solid newBolt; 
    
    // List of all components inside the assembly
    Features components; 
    
    // Single component feature from the assembly
    ComponentFeat component;
    
    // Descriptor used to identify component model & instance name
    ModelDescriptor desc; 
    
    // Replace operation object
    CompModelReplace replace;
    
    // Collection of replacement feature operations
    FeatureOperations replaceOps;

    // Instance name of the existing bolt to be replaced
    String oldInstance = "PHILLIPS7_8";
    
    // Instance name of the new bolt to insert
    String newInstance = "SLOT7_8";

    try {
        // Get the active Creo session with C4 compatibility
        session = pfcSession.GetCurrentSessionWithCompatibility(CreoCompatibility.C4Compatible);

        // Load the base bolt part model
        bolt = (Solid) session.GetModel("BOLT", ModelType.MDL_PART);
    }
    catch (jxthrowable x)
    {
        // Handle error when loading session or model
        System.out.println("Caught exception: " + x);
        x.printStackTrace();
        return;
    }

    try {
        // Retrieve the family table row for the new bolt instance
        row = bolt.GetRow(newInstance);

        // Create a new instance of the bolt from the family table
        newBolt = (Solid) row.CreateInstance();

        // Initialize the feature replacement operations list
        replaceOps = FeatureOperations.create();

        // Get all component features in the assembly
        components = assembly.ListFeaturesByType(
                Boolean.FALSE,
                FeatureType.FEATTYPE_COMPONENT);

        // Loop through all components in the assembly
        for (int ii = 0; ii < components.getarraysize(); ii++)
        {
            component = (ComponentFeat) components.get(ii);

            // Get the model descriptor of this component
            desc = component.GetModelDescr();

            // Check if this component matches the old bolt instance
            if (desc.GetInstanceName().equals(oldInstance))
            {
                // Create a replace operation to swap with the new bolt
                replace = component.CreateReplaceOp(newBolt);

                // Insert the replace operation at the beginning of the list
                replaceOps.insert(0, replace);
            }
        }

        // Regeneration instructions (used to refresh model)
        RegenInstructions regenInstrs = null;
        
        // Window reference for repainting
        Window window = null;

        // Get the currently active model
        Model currentModel = session.GetCurrentModel();
        
        // If the active model is the same as our target assembly
        if (currentModel != null &&
            currentModel.GetFileName().equalsIgnoreCase(assembly.GetFileName()))
        {
            // Get the display window for that model
            window = session.GetModelWindow(currentModel);

            // Create regeneration instructions
            regenInstrs =
                    pfcSolid.RegenInstructions_Create(
                            null,
                            null,
                            null);

            // Force the model tree to refresh
            regenInstrs.SetRefreshModelTree(true);
        }

        // Execute all replacement operations and regenerate the assembly
        assembly.ExecuteFeatureOps(replaceOps, regenInstrs);

        // Repaint the graphics window to show updates
        if (window != null)
        {
            window.Repaint();
        }
    }
    catch (jxthrowable x)
    {
        // Handle all replacement/regeneration errors
        System.out.println("Caught exception: " + x);
        x.printStackTrace();
        return;
    }

    // Exit method
    return;
}

I‘m not the jlink guy, but what I see in your code (I may wrong), you create a new instance, but it is basically the generic one, so no difference.

Prepare your family table in that way, to see a difference for the replaced one. Next in your code, get the handle for the instance  to replace, instead of creating a new instance.

Here (other language) replace ins30.prt with ins10.prt
