AutoCAD Student Edition is a version provided by Autodesk for education, which has all the functions of AutoCAD, but it will display the stamp of "Generated by Autodesk Education Edition" when printing, so it cannot be used for other commercial purposes. At present, Autodesk Student Design Alliance provides authorization 13 months. Of course, new software will come out after 13 months, and 20 12 will come out soon.
