At most you might want to verify that the data in the XYRS file

Why do you think you need to verify the results by reverse engineering
the code??? That is the stuff I am talking about over thinking the

I'm guessing here, but pick and place machine have to orientate the

a principal axis of inertia. It is not always easy to determine where
the axis lies when the component is asymmetric, which is frequent

My mechanical cad demo has a similiar feature: 5 buttons that

A nc pin would be like pas, but gives no error if unconnected.
The documentation of the Renesas TinyH8 states:
... Do not connect anything to the nc-pins. They might be used as test
I have seen this handled in other CAD packages not by making the pin
an NC in the symbol, but by having a feature in the schematic where
the pin can be No Connected so that it is not flagged as an error
if it has no wire.
Or course, it makes some sense to have a special type of NC in a
Hi, im new on geda, and have installed the latest version.
There are changes or problems when i try make a footprint and call it
from xgschem2pcb??
Only one footprint (only one pin) do not appear when i touch the button
update layout in xgschem2.
Thanks!!
I'm having trouble with layers in pcb and can't find any relevant info
either on the web or in reading back through several hundred archived
messages, so I figured I'd just ask.
I'm using version 20080202 (because that's what's in the repo I use.)

Excellent! If you could put update the readme and built script for
windows high on the priority list, it will save us much headache in

One way would be to directly add my script to the pcb sources. I would
trim it down for building only pcb
I prefer replacing the scripts already in pcb, to avoid confusion.
