With coronavirus (COVID-19) affecting communities and families around the world, Autodesk has announced a temporary Extended Access Program for several cloud collaboration products, including BIM 360 Design, to better support customers during this time.

The Extended Access Program for BIM 360 Design gives users the ability to use a BIM 360 Design trial on commercial projects, starting from Mar 25, 2020 with a current end date of June 30, 2020. View the terms and conditions unique to the Extended Access Program.

As a participant in the Extended Access Program for BIM 360 Design, there are a few actions you will need to take prior to June 30 – to ensure both the continuity of your projects, and retention of your project data, once the Extended Access Program comes to a close. To see what options are available to you, please visit the Extended Access Program Transition Guidance. Your Autodesk representative or reseller can also support you in implementing any of these options, whether you choose to subscribe or not. You should feel no pressure to buy at any point in this program.

View the COVID-19 Autodesk Resource Center for more information.

Following the expiration date of the Extended Access Program, standard trial terms and conditions for a 30-day product trial will apply.
