When rev'ing a schematic on older versions I would just copy the directory and change the rev. suffix (e.g. B to C). I would text edit(notepad) the dproj and .db files for my new name and paths. I tried this with 9.5 (edited files .prj and .db, but can't get the schematic sheets to show up when I go into DxDesigner. Any help would be greatly appreciated.
