It's been almost two years and offline export is still bugged. 😞
I just got hit with same thing today. I started a design while working offline (not by my choice, it's maintenance time ... again, and who knows for how long).
Same error message about autodesk services unable to convert the file.
When I try to create a new design and NOT SAVE IT, then I can convert a body to STL without issue.
It's only when an offline design is saved and then you attempt to export STL file, while in offline all the time, it fails no matter what you try.
I am starting to get tired of this "always online" concept, that stops working when you least need it. 😞
Why such a basic functionallity as model conversion to triangles can't be done on my computer locally? It is not a super computer task, just a dumb format conversion. I just don't get it.
Any hope of reopening the issue and actually fixing this bug?
Thanks.
