You didn't respond to that, so again:
Make sure BACKGROUNDPLOT for publishing is OFF (0 or 1)
and use the 'Publish in' option: PDF
Still an issue?
with all files?
>> "and lose all work"
Usual rule, save your work from time to time, specially before you start function which you have trouble often.
And the publish list can saved too.
Autocad don't have a automated Backup, just isavebak for backup the (pre-)last saved file version.
The "internal" Automatic Save file, can safe your unsaved edits, but it is not bulletproof, so as a user you shouldn't rely on that.
- Automatic Save (SV$) drawing file – A temporary drawing file created after a specified time interval has been reached since the last time the open drawing was saved. Controlled by the Automatic Save, or Autosave, feature of AutoCAD.
Attention: The Automatic Save timer is reset each time the drawing is saved. This can cause AutoCAD to never create an Automatic Save (SV$) drawing file for an open drawing. So, for example, if you have the time interval for the Autosave feature set to 10 minutes, and you perform a save operation every 2-5 minutes, an SV$ file won’t be created.
