i work on AutoCAD 2010 and one of the engineers i work for uses AutoCAD 2007, i use leader for call outs and such and every time he opens it on his computer to print, the leaders disappeared... how do i get leaders to transfer from 2010 to 2007. the only thing that i can figure out is that on 2007 theyre called leaders and on 2010 theyre called multileaders... help please
