That's correct, my position would be as a supplier.
I can tell you having formerly worked in teh steel joist industry that there would never be steel joist placement (shop) drawings issued with an engineers stamp on them.
I am looking for some opinions on the requirement for sealing shop drawings.
I work for a company that supplies various architectural components for buildings. We provide placement drawings for our products, much like for example steel joist drawings, which show a product mark #, location, etc...
