this is the first time i encountered such error.
when generating artwork, there is a message that i need to run dbdoctor,
and when i run dbdoctor, the attached image appears. what does it mean?
i cannot output the gerber data with the errors.
Just a guess...Was this a translated board or made from scratch in PCB Editor? If it was a translated board is sounds like there may be some illegal characters in the package name.
In reply to KEN13:
Actually I did not design the board so i do not know the details, my boss just told me generate gerber data out of the brd data he gave me.
I really can`t fix the errors, but what I did is that I uncheck the "check data base" when generating artworks. I don't know if that is OK but I have successfully generated artwork. And I think the dbcheck errors are not related to artwork since they are all concerned with the packages. Thanks for your time.
