There is if you print instead of plot. For both schematics and boards there 
is a print frame ref checkbox (that is on by default) in the print dialog.

So, just un-check the box and do a print to file with a compatible HPGL 
printer and you should be good to go.

The file (dxflib_commercial_license.txt) that give some info on 
dxflib licence in the downloaded dxflib was very unclear.
In fact the dxflib site is unclear and very poor about the license: 
The dxflib license appears only in a FAQ ...

Yes, it is indeed rather vague on their website. However, the source code files 
themselves do contain a short form reference to the GPL:

** This file may be distributed and/or modified under the terms of the
** GNU General Public License version 2 as published by the Free Software
** Foundation and appearing in the file LICENSE.GPL included in the

so it looks like it is okay for use in GPL'd projects.

Also, FYI, the library seemed to build okay under a default MinGW 5.1.4 
installation. Haven't done anything with it yet, though.  ;-)

In the Module Editor, from PCBNew, open your local module library (or create

 I am just starting to think about using KiCAD for capturing some small

 How could one use KiCAD cvpcb and/or pcbnew to show the traces and hole
 patterns that exist on the commercially manufactured  board, then place
 the components where they will go on the board?

I don't believe there's an existing library for this, but there's nothing 
preventing you from creating a template board file with just the tracks, and 
then open a copy of that template onto which you would place your components.

AFAIK, the design-rule-check (DRC) may not see the pads as connected to the 
traces unless they land iexactly/i co-incident, so you're assuming more of 
the responsibility of checking that all and only the right things are connected.

With that in mind, however, it should work.

Alternately, there is a layout program that's designed to work with 
stripboard-style protoboards. Kicad can create netlists that it can read, so 
you will get routing and DRC capability. The program is VeeCAD; it's over at 
http://veecad.com and there is a free version available.

Stripboards are available from various vendors. One I've found on the 'net with 
decent prices is Futurlec at http://www.futurlec.com/ProtoBoards.shtml

 But you always need to have the vias/nodes connected with traces first.

Not with the most recent release. If a net is first selected when laying out a 
zone then the fill will add connections (using thermals) to pads that are part 
of that net. The resulting connections will (mostly) pass DRC so they are truly 
seen as connected.

Zone fill is not 100% perfect -- some pads that appear to be connected may 
still show on the DRC as unconnected (not sure why), and I've had some 1-pin 
mounting holes become overlaid with the zone -- but it's much smarter than it 
used to be.

One footnote. If a pad needs very narrow traces, such as a connection to a 
fine-pitch QFP, one may still need to make a manual connection with an 
appropriate narrow track if the track width that the zone uses is so wide that 
it can't get to the pad.

With the latest rev, you don't need to create tracks between pads that will be 
connected to the zone; thermal reliefs will be automatically created, with the 
relief widths of the size specified in the zone fill dialog.

Two exceptions to this. You may want normal reliefs to be wider than will fit 
into a small pad, like a TQFP. In that case, use a narrow trace and connect 
that pad to another component on the net as usual. The other exception would be 
power pads where you might want much larger traces. Again, draw these 
separately at the desired width.

Once you fill the zone, any existing traces will be merged to the zone in the 
Gerber file and won't be separately visible in the final board.

There is no single best. In general, you can pay more (sometimes 
much more) for faster service and prettier boards or pay less 
(sometimes much less) for a slower turnaround and and more basic 
boards (e.g., no silkscreen or solder mask).

If you've not send a board out before, one thing to be sure to check 
is the diameter of any through-holes (including vias). Know whether 
you're looking for a diameter before plating (raw drill size) or 
after plating and know whether the hole diameters that result are 
really appropriate for the parts you intend to use. 

PCB Express http://www.pcbexpress.com/index.php isn't the cheapest 
but they'll do well for your first couple of runs until you're more 
comfortable with the process. At a *minimum* read through their pre-
order checklist and FAQ, even if you decide to go with somebody else. 
Other places will have different free drill sizes but otherwise 
it's pretty good advice.

If you can wait a little longer, Sparkfun runs a batch fab at http://
www.batchpcb.com/. You'll save a little but expect to wait. OTOH, you 
may receive more boards than you ordered (at no additional cost) if 
they used yours to fill in the gaps to complete a panel.
