1. After the printed CAD drawings of the education edition, an education edition stamp was added and converted into the normal edition (that is, the education edition stamp in CAD was removed). There are two steps: (1) open the drawing with AuToCAD software, save it as a dxf file, then close CAD(2) reopen AuToCAD software, and then open the file in. Dxf format has just been saved, and then saved in. Dwg format (that is, restored to CAD files), so that the logo of the education version can be removed.
2. Note: If AuToCAD software is in. Just dxf format, and the command prompt is invalid. It is recommended to open it with a higher version of AuToCAD software, and it is best to save it to a lower version (generally save it to version 20 14).
