★ Open the drawing with printing stamp with corresponding version of CAD, execute dxfout command, save it in a folder, then open a new drawing, use dxfin command, import the file just saved, and then save it in DWG format. (It may be automatically converted to dwg format when saving) If it comes, the print stamp should be removed. (Some files cannot be deleted, DXF input is invalid or incomplete-the drawing was abandoned. You can refer to the next post at this time. )

★ Open this file with dwg Express 6.0, convert it to any version (neither format nor version can be converted), and save it as another dwg file.

★ Or like this: change the file ACPLTAMP. ARX eliminates the print stamp by using another name or deleting it in the cad root directory.

★ Or like this: 1. Open any non-educational autocad, whether in 2006, 2005 or 2004;

2. Open the saved file of Education Edition, then save it as, and select "*". Dxf "format file content;

3. Close the file and open the dxf file you just saved as;

4. Save as dwg file, and the repair is successful;

★ Or copy the graphic content in the file that shows the printed seal after the high version is opened, paste it into the R 14 version, save it in the R 14 format, open it with the high version, and then save it in the normal format, so there will be no such display. (Convert it to r 14, open it in r 14, create a new file, and paste all the contents into a new drawing to save).

★ After some files are saved as dxf documents, they can't be opened or eliminated when opened with dxf, and the DXF input is invalid or incomplete-the drawing is abandoned. At this time you can refer to the next post:

First, open the document stamped with the education version and save it in dxf format, then open Acme CAD Converter 8.2, open the "Conversion" menu, select dxf→dwg, open the dxf document to be converted, and convert it into any version of dwg at will.
