My CAD software was not an educational version when it was installed, but I took a CAD as an educational version. As long as I copied it, it became an educational version. How to solve it?
It's because you took a graphic test and activated the command of the education version with the command. When printing, there will be something like "educational edition production" on the four sides automatically.
Method: 1 Save your CAD file in dxf format. 2. Close the current file, save it or not, and see if anything is drawn. 3. Open the saved dxf file. 4. Save it as dwg file again and replace the original file.
All right.
