One version of AUTOCAD is dedicated to education, and the education version is for education and training institutions, such as schools. The educational moderator who uses the software in that organization mainly teaches learners how to use the software. This version is free, so leave a mark when printing. The method of removing the seal of "Made by Autodesk Education Edition Products" when printing CAD If you already have drawings printed by education, you should use this method. The stamp of the drawings that have been used in the education edition cannot be removed under any circumstances. The only solution is to save this file as a DWG file of version R 14 (AutoCAD2000 or AutoCAD2002 can be used). If yours is not an education version, as long as there is a print stamp, it means that you have inserted or quoted a file element drawn by the education version software (even a line will go wrong), so it will continue to expand to any of your files through a simple cad element like a virus.
