I have been annoyed by this for multiple years, and such an issue still exist in the latest version.
So, if you have a 2D drawing in a saved and no update state (no "*" mark on its tab), and you export it to DWG, Fusion will consider such export as a change to the file and therefore put a * mark on the tab. If you attempt to close the file, Fusion will ask you to [Save][Don't save][Cancel].
Fusion used to behave like this when exporting PDF as well. In the current and latest version, this seems have been fixed, though exporting to DWG still see such issue.
It doesn't sound like a big deal, but when you are in the middle of updating a whole bunch of design files, this makes you constantly second guess yourself about whether you've saved the latest changes or not and if increasing the version number is actually necessary. More often than not, you ended up with a bloated version number.
Appreciate if someone can confirm if this is indeed a bug, or if I missed anything and there's a good reason behind such behavior...
And if it is indeed a bug, I'd appreciate if lovely devs can fix it soon-ish.
