Terms of use and the cloud
This is a free, closed Autodesk service, not open source, and use is subject to the Autodesk terms of use. Files are uploaded to the Autodesk cloud and stay available for 30 days; a signed-in user can extend them by another 30 days each time. For confidential projects, think about this first or prefer a viewer that works locally.
