are we speaking about 99SE or DXP ? i can't tell
re 99SE we don't have problems with - or _ in footprint names BUT! spaces are bad they prevent the UPDATE footprint from lib from working at all
is this fixed or changed in DXP ?

Hi Darcy, Sorry for not responding sooner but our email was down just before Xmas and only recently has been restored.
I have seen this issue sometime a long time ago. I cannot recall with certainty why it occurs but I do have one question which may lead to the solution. If I recall correctly this may be related to footprint naming conventions. There are a couple of quirks with footprint naming that are not documented by Protel. At least not clearly. Are your footprint names over 12 characters? There are some functions which will trip up at names over 12 characters. Do your footprint names contain "-" or "_"? One or the other of these also causes some issues. Did you change these component footprints recently? i.e. are they still the old footprint but have the new footprint name? This is what I can recall from my experiences the name updated but the footprint didn't update.
The cause (if I remember correctly, it was about 4 years ago) is in the naming of the footprints. With one or more of the issues I question above the footprints do not update but the name will update. Good luck, hope you find the answer.
If you do find the answer please repost the results. It is so long ago that I forget the cause I found. I just changed my common practices and have never seen the problem again.

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
