That's true.
Anyway, my point is that newbies seem to have a hard time with more
mundane things like the footprints being syntactically wrong, or
perhaps not on the correct search path. The best that a bunch of Free
Doggers could do is verify that each footprint loads without error
into PCB from a .sch export (via gsch2pcb). It is really up to the
user to verify that the footprint will correctly fit the part.
As a first pass, I often read my Gerbers into GCPrevie (*ugh*!
Windoze again!) and then print them out 1:1. Then I place my parts
on their footprints to verify that they fit correctly. This doesn't
catch subtle errors like 2 mil too short for a solder foot. But since
most footprint errors are large and not subtle, my method catches a
lot of errors.
I'd do it with PostScript output straight from PCB, but I understand
that PostScript's 1:1 doesn't really mean 1:1 exactly. Or am I wrong?
