How to get from FreePCB to AutoCad or just print; or suggest a better suite.

Is there a way to get the PCB trace from FreePCB to AutoCad?  I was
hoping that I would get lucky and just be able to copy and paste but
that hasn't worked at all.

I just gave CDNEX a shot too but without any luck.  CDNEX is supposed
to be able to take the gerber files and translate them into .dxf.  I
don't know anything about gerber files and when I try to run CDNEX I
get an error 20 after giving the layer number.

I could also possibly settle for being able to print from FreePCB but
although I see the option to print, it is always grayed out and won't
allow me.

I've been struggling my way through various free programs trying to
accomplish a goal and pretty much going with whatever programs I've
been able to figure out.  Right now I am using:

LTSpice - for circuit simulation and netlist export.
FreePCB - for netlist import and component placing.
fpcroute - to export .dsn files.
freerouting.net - to do autorouting and export .ses files.
FreePCB - again to import the .ses files and do some final editing.

I would prefer to be able to get the graphics on to AutoCad so that I
can have full control of the PCBs appearance.  I also like the way the
vector graphics print.  I need to print so that I can produce the
occassional Gootee board.

Any suggestions on a suite of programs to accomplish all of this?
These are all free of course so I would prefer suggestions for free
programs but I might be willing to spend a total of about $200 to be
able to accomplish all of the above tasks.  Also, I'm running
windows.  I would love to run Linux but it is not an option for me
right now.  Also, the last time I tried to use Cygwin I found it to be
a lesson in futility.  In other words, the gEDA package sounds great
but I probably won't touch it unless it comes in a windows friendly
package.

Any help is appreciated.
Thanks,
ll

To a guy with a hammer, everything looks like a nail??

An "ECAD" seems so much more apt.

Please *do* specify why not.
For $200 you could easily buy another HDD to use as a Linux partition.
Hell, you could probably use someone's cast-off HDD for free.

...or was it a *libraries* problem?

There's nothing more "free" than gratis AND libre.

Considering the hoops you're already jumping thru
and your apparent unwillingness to add a Linux partition,
*this* would be no more cumbersome a solution
to getting gEDA working on a Windoze box:

In addition, if you are a Windoze user
and are such a fan of free software,
it's hard to believe you haven't stumbled across KiCAD.

You've got me all wrong, I'm a guy with a nail and everything looks
like a hammer!

Okay, I'm happy to indulge anyone that has tried to help me.  I can't
install Linux on my work pc, my pc at home is down and I haven't
touched it in months, and the HDD on my laptop is full.  I used to
think of myself as a computer guy but lately I'm fed up with fixing
computers so I probably won't work on my pc until I have to.  Other
than that, I don't have a good excuse for never installing Linux.
I've had Debian/Libranet on disc for years and have never got around
to installing it.  Right now I am frustrated that I have spent more of
the past two weeks fooling around with computer programs instead of
actually building the PCB.

The first time I ever heard of Cygwin was when I needed to do some CFD
Flow Modeling.  Documentation was scarce and it seemed that everyone
assumed the end user was familiar with the process.  I don't know if
it was more of a problem with Cygwin or with the CFD program.  I would
fix my computer and install Linux before I ever try to use Cygwin
again.

I'm guessing here but it sounds like "a Knoppix like gEDA disc" is a
bootable CD that runs a Linux OS and allows gEDA to be run?  That
would be cool.

Yes, hard to believe I guess.  It looks very impressive, I think I'll
try it.

After this project is done, I probably will install Linux and go with
the gEDA.  I just can't stand putting this project off anymore.

Thanks,

--snip--

Further reading in the FreePCB documentation revealed that the
printing options haven't been implemented yet.  It also suggested the
use of ViewMate 9.6 which I am able to print from just fine.

I'm still open to other suggestions to go from simulation>autorouting/
manual routing>printed PCB pattern.

Thanks all,
