Format for XYRS file

I am being told that the XYRS file my CAD software generates is 180
degrees out. I guess there is some sort of convention or standard,
but I can't find where that is described. I get the impression that
most assembly houses are happy to even get a file.

The program I am using has options for selecting things like the
rotation direction. How do I know what is correct? In the emails I
have exchanged, the assembly house seems to feel that whatever works
with their machine is the "correct" convention even if they can't tell
me what it is. Anyone know how to define the data in the XYRS file?

I forgot to mention that I found that gerbv can load in XYRS files
along with Gerber files. But when I tried to use it on my machine, it
crashes when I try to open a Gerber file. No joy...

Are there any other programs that will let you view XYRS files?

These guys seem to be saying that the assembly house
should be adapting to whatever data you send them.http://www.google.com/search?q=cache:mT33rN6fz_QJ:www.aapcb.com/Resou...

That's the only one I know of.

Actually, the guys you quote above provide a program, BOMbuilder, that
can read in your BOM and XYRS along with the gerbers to *show* you how
the parts will be placed. I tried it, but I found it to be a lot of
work. Plus, when I tried to get a quote from them, they didn't seem
to really care about the output of the program. I got the impression
that they don't consider it a useful front end tool for their use.
Maybe I didn't get the correct impression, or maybe I have not learned
enough about the tool yet.
