Abd ul-Rahman,
I was supplying a view of what we do for our documentation, not
suggesting it was the only way nor the way that everybody should/has to do it.
I don't know the full history behind our methods but they are complete,
succinct and readily/quickly created once you have the basic methodologies
down, no more work than flipping or rotating Gerbers.
Yes all of the information can be manipulated and derived through other
means but in the end you still have to flip/rotate at least the Gerber data so
it offers no more efficiency than rotating and flipping the original design for
post fabrication documentation. None except that the Gerber is dumb so you then
have to rely on working with two files (the flipped/rotated Gerber and the
original PCB file) for your full production data rather than cleanly all
encompassed within one file.
Sincerely,

The gerber solution is only for the purpose of producing flipped
human-readable documentation; I've never needed to do this except for
bottom-side assembly drawings. Yes, the gerber contains no
intelligent part information, but this solution allows a single
drawing to show both top and bottom assembly. If you want to make
separate drawings, you might do something different, but.... you
might still do what I suggested, only in a separate file.
