Here is an example iLogic rule for taking the 'longer route' alluded to by my first several links above. Likely not very ideal way to do it, but here it is anyways. Be careful, because I have not tested this yet myself, because I have no use for it. I included some comments within the code to attempt to explain what the lines of code are supposed to be doing.
Sub Main
'<<<< CHANGE THESE NEXT TWO LINES AS NEEDED >>>
Dim sTemplateDrawing As String = "C:\Temp\My Drawing Template.idw"
Dim sDwgStdStyleName As String = "Drawing Standard Style Name"
'<<< now open template drawing (invisibly), so we can copy style from it
'first make sure specified template file exists
If Not System.IO.File.Exists(sTemplateDrawing) Then
MsgBox("Drawing Template File Not Found!", vbCritical, "Template Not Found")
Return
End If
'open the template drawing invisibly, so that we can access its contents
Dim oTemplate As DrawingDocument = ThisApplication.Documents.Open(sTemplateDrawing, False)
'get specified DrawingStandardStyle object from it
Dim oTemplateStdStyles As DrawingStandardStylesEnumerator = oTemplate.StylesManager.StandardStyles
'create variable to hold DrawingStandardStyle when found
Dim oTemplateStdStyle As DrawingStandardStyle = Nothing
Try 'try to get that style using the specified name
oTemplateStdStyle = oTemplateStdStyles.Item(sDwgStdStyleName)
Catch 'don't react to any error
End Try
'if not found, let user know, then exit rule
If oTemplateStdStyle Is Nothing Then
MsgBox("DrawingStandardStyle named '" & sDwgStdStyleName & "' could not be found in template!", _
vbCritical, "Source DrawingStandardStyle Not Found")
Return
End If
'<<< get current drawing - assuming current Document is an older drawing that you want to update
Dim oDDoc As DrawingDocument = TryCast(ThisDoc.Document, Inventor.DrawingDocument)
If oDDoc Is Nothing Then Return
'<<< get old drawing's DrawingStylesManager
Dim oStMgr As DrawingStylesManager = oDDoc.StylesManager
'<<< get old drawing's Active DrawingStandardStyle
Dim oActiveStdStyle As DrawingStandardStyle = oStMgr.ActiveStandardStyle
'<<< prepare necessary variables for extracting needed data from that style
Dim eViewType As DrawingViewTypeEnum
Dim sPrefix, sFText As String
Dim bVisible, bConstToBorder, bPlaceBelowView As Boolean
For Each eViewType In System.Enum.GetValues(GetType(Inventor.DrawingViewTypeEnum))
'reset variable values, to make sure their values don't carry over (may not be necessary)
sPrefix = ""
sFText = ""
bVisible = False 'default value of a Boolean
bConstToBorder = False
bPlaceBelowView = False
oTemplateStdStyle.GetViewLabelDefaults(eViewType, sPrefix, bVisible, sFText, bConstToBorder, bPlaceBelowView)
oActiveStdStyle.SetViewLabelDefaults(eViewType, sPrefix, bVisible, sFText, bConstToBorder, bPlaceBelowView)
Next
'<<< update drawing
oDDoc.Update2(True)
'<<< release reference to invisibly opened template document
oTemplate.ReleaseReference() 'similar to Close method, but for invisibly opened documents
