Component tagging

I have just updated my component tagging code; you can use it as an external rule or straight in the drawing. Would like to thank Chris Benner for taking the time to test this. Check out his blog for more Tube and Pipe stuff
I have merged part tagging in the assembly and retrieval in the drawing intro single code that should work like this:

I would recommend that you create a new balloon style called "Tags" or you need to edit the code and add a comment character ' before the line:
oBalloon.Style = oStyles.BalloonStyles.item("Tags")
This code has been stripped out from the inventor help pages.Unfortunately it's only working with curve segment and when trying to get the middle of it as your balloon attachment reference it's not returning anything for circles and ellipses but for the rest it creates a leather point about 0.5 on axis X and 1 Y .So you can increase these values to get the balloon further away from your reference.

The assemblies need to be checked out, including the runs that contain the parts to tag (valve and all).
Sometimes when you work with different level of details and designs view representations it fails finding the component occurrence so that's why I'm asking you to place a parts list on the drawing sheet (the code tracks and reports if this is the case).
You can’t have same name for different components inside an assembly, so the code will prompt you to try again if you type in an existing value. Ex.: Inside each Route you can have only one valve code V101.
In the tag window dialog if you press cancel it reverts to the original value but make sure you update all balloons at the end when prompted.

You can change the balloon style hexagon linear circular, you can change the display diameter size ; you can change the format of the text but I would much rather change it in the style manager of the drawing create a new style and assign the balloon to it instead of manually entering all these parameters inside the code.
 The second part of the code prompts for update on existing balloons. Here is the code to download.

'this sets a tag to each selected component and creates
'a balloon for it, asks for update of existing balloons
' Set a reference to the drawing document.
' This assumes a drawing document is active.

        If oCS Is Nothing Then
            'MessageBox.Show ("Selection was cancelled","ilogic")
            Exit While
        End If
        oCurve = oCS.Parent
        oEdge = oCurve.ModelGeometry
        occurrence = oEdge.ContainingOccurrence
        'MessageBox.Show("Old Occ name: " & occurrence.Name,"ilogic")
        Retry = True
        'as long as retry is selected by user
        While Retry
            'get tag from user
            oTagOcc = InputBox("Enter Tag No: ", "Tag Prompt", occurrence.Name)
                ' try and set that value
                occurrence.Name = oTagOcc
                'if success exit the retrying loop

        'if user canceled the retry skip the rest of the code and
        'prompt to select parts again
        If Retry = False Then
            Continue While

Try this out, and customizing for your needs.  Let me know how that goes for you.
