Eagle holes/pad widening

I'm a new user of eagle, and I've managed to get through designing my
schematic to designing a PCB. I want to print via laser printer from
eagle on to some transfers which iron on to the copper, ready for
etching.

I can see that I can widen tracks in eagle, which is great, but the
copper area around holes is too small for me to solder on to. Is it
possible to expand these circular pads without editing each and every
library item at all?

Regards,
Mark

Yes, you can change the restring (usually called annular ring) in the
Restring tab of the DRC window. Don't ask me why its in the DRC area
but it is.

You will probably want to make the minimum larger but play with it.
What you see on the screen is a close representation of what should come
out in the output files.

I beleive I should mention that Cadsoft has multiple great newsgroups on
their server too. Very helpful folks there including the authors:
news.cadsoft.de

Thanks James

I kow DRC stands for design Rules Check, but does running this actually
change your board layout then? As you can see, I've never run it
before.

hey thanks, I read news on google groups, but when I get home, I'll
connect to the news server you suggest, thanks Mark

No.
It flags stuff that doesn't match the specifications (e.g.,
clearances).
At that point, YOU can
1) change the layout
2) change the rules
or
3) cross your fingers and ignore the prompt

Except that in EAGLE you can set all sorts of parameters in the DRC that
actually do change how the Gerbers get generated. For example, that is where
you go to select which vias get tented, what kind of blind/buried vias are
allowed, what thermals look like, and other things like that. It is more
`design rules' than `check.'

I don't know how to widen pads that way but I can believe that you can.
