Hello,
I have a revit file downloaded form the autodesk360 portal, I can preview the file on their web interface, but when I downloaded, and try to opened the "Failed to Open Document" shows up.
I have tried several Revit versions, Navisworks, 3DS max, with no luck.
Using a CTC tool to read the Revit version, shows as unknown version. see attachement
Thank you for your help.
Fernando
