Using API to change property in balloon style

DWhiteley — Thu, 15 Dec 2016 16:15:44 GMT

I've got a drawing with a part ballooned in it.

What I would like to do is edit the style using the API so that the property in the balloon is pointing to a customer property in that part.

I've tried:

Dim oBalloon As Balloon
For Each oBalloon In oSheet.Balloons

oBalloon.Style.Properties = "customproperty='ITEM#'"

....

This doesn't work. Has anyone got any ideas on how to do this?

Thanks in advance.

Dim drawDoc As DrawingDocument 
Dim currentSheet As Sheet
Dim oBalloon As Balloon 
Dim valueSet As BalloonValueSet

currentSheet = drawDoc.Sheets.Item(page) ' insert your page number here i.e. 1 or 2 or 3 etc
x = 0

    For Each oBalloon In currentSheet.Balloons
        x=x+1
        Try
        Dim oBalloonType  As BalloonTypeEnum 
        Dim oBalloonData As Object 
        Call oBalloon.GetBalloonType(oBalloonType, oBalloonData)
        Dim oBVS As BalloonValueSet 
        oBVS = oBalloon.BalloonValueSets(1)
            If InStr(oBVS.OverrideValue,"A1") > 0 And oBVS.Value = 185 Then 'This line is looking for a balloon with a specific string in its override value and that also has a balloon value of 185 which is based on the part it is referencing 
               oBVS.OverrideValue = Parameter("Part1.ipt.Parameter1") 'change the override value of the balloon to a specific parameter from a specific .ipt file
            End If
            'add more if statements if you want to change the value of more than one balloon
        Catch
        End Try
Next

At the end of the day, changing balloon values is very difficult and fussy. I opted to instead create leader values with text since it is much easier to interact with than the balloon function.

That's brilliant, thanks Nick. I'll give that a go.
