LabVIEW Class Icon Glyphs from NI

As an example, let's suppose we have a hierarchy of classes representing errors, very similar to the job that the error code cluster does in LabVIEW. We use as the glyph for error code in LabVIEW, so the hierarchy might look like this and use the following icons. LabVIEW Object | + -- Abstract Error      |      + -- General Error      |      + -- Device Error      |      |      |      + -- DAQ Error      |      |      |      + -- GPIB Error      |      + -- Network Error      |      + -- User-defined Error The glyphs can be stacked and arranged together to create a class library icon that will be the banner across the top of member VIs.
