When I tried to save the contents viewer3D.min.js received via the autodesk api, the viewer launch failed with an error.
Is it possible to keep viewer3D.min.js locally on your project?
Unfortunately, you cannot do that due to the Forge Viewer Usage Limitations, but you can implement a disconnected workflow by using the Web browser's cache. Please check out this blog post for details: https://forge.autodesk.com/blog/disconnected-workflow
Usage Limitations
The Autodesk Forge Viewer JavaScript must be delivered from an Autodesk hosted URL.
