eDrawings updating

This has come up a few times recently. I make a change to asubassembly and save it. If I don't open & save the topassembly, when my boss opens the top assembly in eDrawings, theupdated subassembly is not showing and he is giving instructions tothe shop floor with the information he sees (the old subassembly).Why doesn't eDrawings open proper subassembly?SolidworksEdrawings
