In This Topic
    GetGraphic Method (GraphicElement)
    In This Topic
    Returns a CIMGraphic which is a CIM representation of the graphic specific attributes for a GraphicElement. This method must be called on the MCT. Use QueuedTask.Run.
    Syntax
    public CIMGraphic GetGraphic()
    Public Function GetGraphic() As CIMGraphic

    Return Value

    Exceptions
    ExceptionDescription
    This method must be called within the lambda passed to QueuedTask.Run.
