We're using AutoCAD 2000. Recently we emailed some dwgs to a vendor who has Ver 14. They couldn't open the files. They suggested that we save our dwg's as Ver 14. Would anyone have any ideas about this? Is it normal for a dwg created in Ver 2000 to not open in Ver 14? Is it possible to save a Ver 2000 dwg in Ver 14 format? Any ideas and comments on this will be greatly appreciated. Thanks, K.
