Mario,
That really sums it up! IPC-7351 does not include silkscreen, assembly,
polarity marking, ref des, 3D model, etc. in the publication.
So a Land Pattern is just the Pads and Courtyard and a Footprint is the
complete CAD library part.
Now we're making progress.
Thanks,
Tom

My initial response to "footprint" vs "land pattern" is that land pattern
refers just to the pads onto which the component is soldered while
footprint, IMHO, refers to the whole enchilada, pads, silk, assy, 3D ... I
create footprints not land patterns for my PCB tool. So, for me anyway,
both terms have a place. Land pattern is a sub set of a footprint.
