Darcy,
I don't have as extensive an internal knowledgebase for Protel
as some of the folks on this forum, but my first thought of course is
who's creating the library parts. Copying existing footprints which then
need to be modified causes grief here sometimes.
Recently I responded to a post on what the various SMD caps
sizes actually refer to, so I assume some folks are still completing
footprint libraries of these parts.
I really have no idea how to go about checking all of the parts
in the library other than physically looking through them. Keep us
posted as to what you discover the problem to be. Hopefully it's a one
off. Good Luck and Happy Holidays.

Subject: [PEDA] Wrong geometry, right footprint name!
Hey Guys,
I ran into a rather disconcerting problem this morning (just before we
sent
this board for fabrication). I found a part in this particular PCB that
had
an 0603 geometry where there should have been a 1206. The really
disconcerting part is that the "footprint" field for this part said 1206
(which is correct). I could have explained this as human error if it was
the
only part. However, further review turned up an 0603 geometry where an
0805
should have been. I'm still looking for other problems.
1) Anybody seen anything like this before? or can come up with an
sequence
of steps that may have caused this?
2) Its going to take a long time to check every part in the design.
Anybody
have any suggestions for finding further errors?
Darcy
