Thanks Tom.

How does the fabmaster data handle this problem? and what property do they
need to see in the Allegro data?

I've always thought this was a funny issue.  The component report includes a
rotation column, but it is a rotation from an arbitrarily drawing footprint,
so it is useless data to the assembly house.

I think that is why many of them prefer the fabmaster data.

I have never been asked this before, but a cm asked why I had no
polarization sense in the pick and place cad data. i.e. for diodes and
tantalums.  They had not even asked for one of the 3rd party outputs like
Valor, Fabmaster or Circuitcam, just the component report out of Allegro in
.xls format.  So how does that work?  Does Allegro have a property you can
attach in the footprint that will come out in any of those reports?
