I'm just learning how to use Solidworks and I cant seem to figure out why when I'm in model view and I'm trying to select a part/assembly to insert and I select browse, nothing comes up for me to actually insert. My textbook is telling me to insert a battery part however I cannot seem to find it. Anyone know if I need to download the parts or if I'm completely doing it wrong?
