You can create a sketch symbol which has prompted entry while formatting the sketch of the symbol. No iLogic required.
I also have symbols that i place under views though using ilogic & forms. This is the code,
You could probably find something usefull in this:
Dim oApp As Application: oApp = ThisApplication
Dim oDoc As DrawingDocument: oDoc = oApp.ActiveDocument
Dim oSheet As Sheet: oSheet = oDoc.ActiveSheet
'This uses a sketch symbol with the name "'View On' View Label"
Dim oSymDef As SketchedSymbolDefinition: oSymDef = oDoc.SketchedSymbolDefinitions.Item("'Item' View Label")
'This is the selected view
Dim oView As DrawingView: oView = ThisApplication.CommandManager.Pick(SelectionFilterEnum.kDrawingViewFilter,"Select View To Place Symbol:")
'This takes the label items of the selected view
'And adds it To an array that will link To the prompted entry
Dim sPromptStrings(4) As String
sPromptStrings(0) = oView.Name
sPromptStrings(1) = oView.ScaleString
sPromptStrings(2) = ""
sPromptStrings(3) = ""
sPromptStrings(4) = ""
'This is the position for the sketched symbol under the selected view'
Dim oPosition As Point2d: oPosition = oView.Center
oPosition.y = oPosition.y - (oView.Height / 2 + 2.5)
'This inserts the sketched symbol and fills in the prompted entry.
Dim oSymbol As SketchedSymbol: oSymbol = oSheet.SketchedSymbols.Add(oSymDef, oPosition, , ,sPromptStrings)
