Unfortunately that beast had:
1) Thru-board vias at the minimum diameter hole size the fab shop would
tolerate
2) Blinds, buried... lot's of 'em
3) Multiple independent power planes - boatloads of coupling and bypass
caps
4) matched length lines - most being differential pairs
5) Controlled impeda
Hi all,
Attaching the new version of the dsub15 hd footprint, instead of
drawing it with a mm grid I drew it with a mil grid and just made the
mm to mil conversions from the diagram of the footprint I have. I also
fixed the soldermask clearances, let me know if this symbol is good
enough now to be

Which model of connectivity should it understand? There isn't just
one. And if you implement one model in the gschem core, it will

Hey TeX uses 32 bit coordinates which an unit which is way

I also did a MAXINT-sized board once. It worked out to be 0.25 miles
across. I had an element the size and shape of my HOUSE and it was
still too small to see.

Do you (or some one else) have a script that will edit the

Hi Stefan,
thanks for pointing this out. I will try to use it next time for small
changes. However, I would have to make sure that I change the
schematic in addition.
Furthermore, I guess a simple gsch2pcb with different footprints in
pcb and geschem would overwrite the local changes i

This is bad -- a weak spot in PCB.
If you modify Footprints in schematics they are removed and you have to
place the new ones again manually.
You can exchange them in

Hi,
I just had to change some footprints for a nearly finished pcb (some
parts was tricky to order from resellers in small quantities).
I used gattrib which allowed me to change the footprints very easily.
After running gsch2pcb, I noticed that all old footprints was removed
from the pcb and I had
