Sure, if attaching a file to a post works on groups.io (it was rather
hit-and-miss on Yahoo groups). If it doesn't work, I'll send the image
direct to you.
The image is confusing if you don't know what it all means. Firstly,
it shows just the left-hand end of the board. The green and the yellow
lines are on the eco1 and eco2 layers, used to show me where are the
keep-out areas on either side of the board. The outer green line
overlays the board profile, so you can't see the lines on the profile
layer, but they're there, baked into the footprint. The purple text is
on the silk screen. The items in grey (the drawings layer) show me
where one of the other engineers wants me to place items that have to be
in a specific position, including the pig-tail pads (I just have to
remember which side of the board they are on). 1 to 9 are pads for a
pig-tail, and the pads marked 10 are for bolt holes that connect
electrically to the metal case. I could have made the pigtail pads a
separate footprint, but it was convenient in this case to do things as I
have. I could also have numbered the pads marked 10 as 9, since in
this case they are connected electrically, but instead I opted to show
the connection on the schematic to make it salient to people looking at
the schematic. Speaking of which, this entire footprint is represented
in the schematic as a ten pin connector. Sometimes I have the board as
a separate component (with or without a connection to chassis); it just
depends on what works best for a particular project.
All the elements you see except the pads are imported from DXFs sent
through from two engineers working on other aspects of the project.
Regards,
Robert.

Hi Robert, can you show how it looks like?
"The board I'm currently working on even has solder pads for a pig-tail baked
into the board footprint."

That's what I do. And if the board profile is something complicated
that has come from a mechanical CAD application (as a DXF), I have a
"board" component that includes the holes, the profile, and anything
else I will need to know whilst laying out (such as keep-outs). The
board I'm currently working on even has solder pads for a pig-tail baked
into the board footprint.
