What license type does Revit primarily use for its software?

Revit primarily uses subscription licensing as its software licensing model. This approach allows users to access the latest features and updates more frequently without the need for a major purchase every few years. With subscription licensing, users typically pay a recurring fee, which can be monthly or annually, granting them access to the software, customer support, and any additional resources provided by Autodesk.

This model aligns with the industry's shift toward software as a service (SaaS), where continuous improvements and cloud-based features can be integrated efficiently. It provides greater flexibility for users to manage their costs and scale their software use based on their project needs.

In contrast, open-source licensing involves software that allows users to edit and distribute the source code freely, which does not apply to Revit. Permanent licensing suggests a one-time purchase model, which may have been used in the past but is no longer the standard for Revit. Trial licensing typically limits access to the software for a short period to evaluate functionality, but this does not represent the primary licensing model for ongoing use of Revit.
