Editing AutoCAD (section)

===Student versions===
AutoCAD is licensed, for free, to students, educators, and educational institutions, with a 12-month renewable license available. Licenses acquired before March 25, 2020, were a 36-month license, with its last renovation on March 24, 2020.<ref>{{Cite web|title=Term length for Educational Licenses {{!}} Search {{!}} Autodesk Knowledge Network|url=https://knowledge.autodesk.com/search-result/caas/simplecontent/content/term-length-for-educational-licenses.html|access-date=2020-07-18|website=knowledge.autodesk.com|language=en-US|archive-date=2020-07-19|archive-url=https://web.archive.org/web/20200719014928/https://knowledge.autodesk.com/search-result/caas/simplecontent/content/term-length-for-educational-licenses.html|url-status=dead}}</ref> The student version of AutoCAD is functionally identical to the full commercial version, with one exception: DWG files created or edited by a student version have an internal bit-flag set (the "educational flag"). When such a DWG file is printed by any version of AutoCAD (commercial or student) older than AutoCAD 2014 SP1 or AutoCAD 2019 and newer, the output includes a plot stamp/banner on all four sides. Objects created in the Student Version cannot be used for commercial use. Student Version objects "infect" a commercial version DWG file if they are imported in versions older than AutoCAD 2015 or newer than AutoCAD 2018.<ref>{{cite web|url=http://docs.autodesk.com/ACD/2011/ENU/filesAUG/WS1a9193826455f5ffa23ce210c4a30acaf-6050.htm|title=Overview of Plotting|access-date=19 March 2016}}</ref>
