The AutoCAD free trial lasts 15 days. The trial software will automatically expire after the trial period ends.
After your trial expires, you cannot extend the trial period. For short-term needs, you can purchase a monthly subscription and turn off automatic renewal (to limit the length of the paid subscription to one month only) or purchase Flex tokens for a flexible pay-as-you-go plan.
Students and educators can get free one-year educational access to Autodesk products and services, which is renewable as long as you remain eligible. If you are a student or educator, you can access free AutoCAD software with an Autodesk Education plan.
When you trial and subscribe using the same Autodesk account, all your project files, preferences, settings, and customizations made in AutoCAD during the trial period will be transferred and accessible.
