I understand there is a new feature in SW2009 like Inventor's "Phantom Sub Assembly", where you can model an assembly of components, e.g. a nut, bolt and washer, and have the BOM display the child components and not the subassembly. Anyone know anything about this? I can't find anything in the "What's New" document, but one of the tech guys told me a while back that it was in 2009. Thanx.
