There is an educational version because someone uses unregistered pirated CAD drawings or someone steals others.
The map itself has an educational version, which will produce an educational version.
Let's demonstrate the method.
Open the education cad, and then load the education plug-in in this area (go to the education AutoCAD 2000 ~ 2014 _ x86 _ x64).
Load according to the number of digits in your computer, save this drawing after loading successfully, and then close all cad software.
Continue to reopen the pictures in the education version, and then you will find that there is no education version.
