Situations like these are a designer's worst nightmare...

It reminds me of the real need to double check the gerbers before going out
to fab, something we tend to take for granted that we expect to always be
ok... I use Protel here and the gerber RS274X outut from the 98 version that
has had 3 service packs installed, seems to be fairly reliable with it's
Gerber output, but before I upgrade to the 99SE software I will run several
tests on the output and read them in to verify that they are correct before
I send anything out....
Also, more than once, Power Circuits in Anaheim, CA, has saved our bacon by
using Valor to check the incoming job and found things like stubs, which
Protel doesn't check for...
It's very important to have a good PCB vendor check you as well... there is
so much riding on the system running smoothly... which is always risky when
you upgrade software versions....
Maybe this bug alert will save another company from the same fate... Thanks,
Mark.

Subject: [DC] Cadence Allegro RS274x Artwork Bug


Has anyone seen problems with generating artwork files
using the Gerber RS274x Format on Cadence?  We are
running version PE13 still and I recently sent out a board
using this "new" Gerber only to find out that one of the
shapes on the top layer did not plot- No errors nor warnings
regarding this were given and the boards will have to be
reworked at a considerable cost and loss of time in the factory.
