What is Revit?

Autodesk provides download and installation instructions both for individuals and administrators. Individuals should sign in to their Autodesk Account or education site. Find your product and click View Downloads. Select the version, platform and language, and then select a download method. For more information, visit Autodesk Support. 

Trial versions of Autodesk software let you explore the full capabilities of the latest versions for a limited term (typically 30 days). To cancel a free trial, turn off automatic renewal before the trial period ends. If you were not required to enter a payment method, it will expire automatically.

If your trial expires, you cannot extend the trial period. For short-term needs, you can buy 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.
