Chad,
Just an update to let you know what I discovered since my last message.
I discovered that LibreCad (LC) does not handle PNG imports very well.
It imports the file, but it is huge. When I tried to "scale" it down by
a reasonable amount, the image disappeared! I later read that LC prefers
vector graphics to raster bit-maps, of which PNG is, and suggests
converting the raster file to DXF using inkscape. I have tried that in
the past, but with less than successful results.
However, I tried exporting the PCB layers I want using the EPS option
instead of the PNG option, and then running the EPS file through
pstoedit, which converts it to DXF, which is LC's native file format for
"blocks". I then imported the DXF file as a block into my LC drawing and
it worked fine. I was then able to make my assembly drawing using the
PCB exported design without re-drawing it. Slick.
BTW: For another "data point", I was going to try to export my design as
EPS without the work-around you suggested (no copper layers selected),
but DJ mentioned in a previous message in this thread that the EPS
option also has the same problem. So, I will not bother testing it.
BTW2: I discovered the "PS" PCB export option produces the same output
as File > Print - all board layers on separate pages - which is not the
same format as the other export options. That was not expected but may
be by design for some reason. It may be more intuitive to "Print" to a
file using PostScript and let the PS export have the same result as the
other export options.

<p>Chad,</p>
<p>Okay, here's what I did. As you suggested, I used the
unused "signal2" layer to create a box around the board
edge and kept it turned on with the "component" and
"solder" layers turned off. In the PNG dialog, I checked
the "screen-layout-order" option and that gave me what I
want - silkscreen, pins, and outline. If I leave the
"screen-layout-order" option unchecked and nothing else
changed, then I get everything again - traces from both
sides and all.<br>
</p>
<p>So, I thank you for your work-around and I can continue
my work wile you get it sorted out. I will look into
posting a bug report ASAP.</p>

<p>Thanks for your prompt response.<br>

<p>Yes, I have "Only-visible" checked in the PNG
dialog. That was the first thing I did, since the
prompt specifically said "...visible items...",
which implies visible on the screen.<br>
</p>
<p>I thought I did this before, but my notes from
then say to enable "Component" side to get pads.
Otherwise will only get silkscreen. Sounds
familiar. However, that board was a single-sided
board, so it didn't matter, since there were no
traces on the Component side. This new board is a
double-sided board. I just checked and exporting
with "Component" layer turned on will produce the
top silk, pins and both component and solder layer
traces, which still is not what I want. I don't
want the traces for this export. According to the
PNG file date on that single-sided board, it was
February of 2015. So, this process was giving me
problems that far back at least.<br>

<p>I have never used LaunchPad before or filed a bug
