I think your original idea was pretty good. It seems like a natural
progression for learning PCB layout or evaluating the tool.
Yeah, you're probably right. I can put the more complex board in the

Hey, a thought...
What if gattrib could accept a *.bom on the command line in addition
to the *.sch ? We'd have to color code the cells to say which
attributes go to the schematics and which to the bom, and figure out
the logistics, but it might fit what we're trying to accomplish.
Looks like it has the relevent info.

That's old. We might have fixed it since then.
This was newly updated together with the newest Ubuntu on an AMD64.
I'm guessing it was the GTK gui, and not the Lesstif one, then?
Although, it works OK for gtk also, for me.
They both look fine to me, but you didn't say which GUI or exporter
you're seeing the erratic behavior in. Some graphics libraries, like
X, act funny when you give them out-of-range angles like that, so
we've been fixing them as we encounter them.

No reason it couldn't be, either. We can hide all that in gattrib and
the netlisters.
No reason not to support multiple BOM files in gattrib either; just
like we support multiple SCH files already.
