Hi,
Autocad desktop allows you to sync drawings automatically to A360 Drive.
Although AutoCAD 360 and A360 should share the same storage, there're currently a few syncing issues between the 2 products. Files that were synced from Autocad desktop directly to the A360 Drive account may not be accessible from AutoCAD 360.
Both teams are working on finding solutions for these syncing issues.
In the meantime, I suggest uploading files directly into your AutoCAD 360 account, open and the edit the files there.
For information about how to upload files to your AutoCAD 360 account, take a look at our new help page instructions for uploading files- http://help.autocad360.com/customer/portal/articles/1110800-how-to-upload-your-files--general-
With kind regards,
