Strange, I can’t seem to replicate the same error.
@bialmeida, I think I might have to agree with @cgartland about your localized version.
Here is my output using MM. It is exactly 1,000 units smaller.

And it does work as a hatch pattern!
To be fair, I had to convert your file to Revit 2020, but I have doubts about whether the upgrade would have solved the issue. However, you might also try out this trick: When I converted the units to Meters in the Manage - Settings Tab, my output went to decimals, shrinking it by… 1,000 units. That may be an easy workaround, but if you happen to narrow down the root cause of the issue on your own, please let us know what it was!
