About the USB connector, don't follow the original part from the
manufacturer, it took me a while to align it.
Here is the step and vrml of that connector. Its the same manufacturer
step, but aligned.

and the connector footprint:

The IDF export is not the problem, trying with a simpler outline
generates the pcb okay but the parts are still rotated.

Hi Maurice,
I just compiled the latest kicad version and the script says
IDF board has to be exported to Xref=0; Yref=0
pcbnew version >=6091
IDF board has NOT to be exported to real placement
pcbnew version < 6091
Anyway, the board is perfectly aligned now, thanks!
I'm using kicad Version: (2015-08-18 BZR 6103)-product release build
and freecad 0.16
I do have a question, the tutorial says "assure that your STEP
module is fused to just one solid object". I see it failing with
multi part obejcts, but I don't know how to fuse a part properly in
freecad.
A boolean operation between parts (union) creates a "fusion" object
that loses color information.
Going through "make compound" in the part workbench seems to be the
right way to do it, but the script is still not happy with the
generated step file and in freecad you can see its not a single object.
See attached an example of a part that I can't fuse together
(X2QFN). I think there are no coplanar faces in the part.
Also, pogo_pin.step looks fine to me in freecad, but when it is
added to a board using the script it gets rotated. Its also attached

The usb connector that is also rotated is here

I'm also having throubles exporting the pcb to IDFv3 of this
particular board, maybe this is related to these rotation issues. I
should ask cirilo later about this.
Thanks

Hi Marcos,
it took me a bit but I managed to align the board.
Now the script can manage also circular board, board with arcs
and pcb rotated inside pcbnew.
I also made an update for the board position for the new IDF
exporting grid.
http://sourceforge.net/projects/kicadstepup/files/kicad_StepUp_v0.519.zip/download
NB this version will put the board at the right position only if
IDF is exported to Xref=0;Yref=0 (pcbnew version > 6091)
I added a starter guide (adoc and pdf) both for kicad StepUp
http://sourceforge.net/projects/kicadstepup/files/kicadStepUp-starter-Guide.pdf/download
and for FreeCAD script generator.
http://sourceforge.net/projects/kicadstepup/files/FC-script-generator-starter-Guide.pdf/download
I patched also the scripting to generate 3D models in STEP, to
be execute correctly also in linux (cadquery freecad module has
been updated too).
(I tested the scripts in ubuntu but it should work also in debian)
Please have a look :)

Thanks Maurice,
the board edge is actually a footprint, and it was rotated
180° in
kicad_pcb file, I don't know if that matters.
About 2), you're right, freecad 0.14 messed up the vrml
export. I tried
with 0.16 and it looks perfect. I'm on a debian box, the
stable freecad
version for us is 0.14, in order to get 0.15 I had to
compile it, and since
it was the same effort as getting the bleeding edge I
compiled 0.16.
I keep forgetting that gmail's inline images are not shown
here, the
screenshot in my last mail was this one (thanks Mario)

Hi Marcos, thank you for the board...
1. I had a quick look and I see the position prob...
IDF import in FreeCAD, with this complex edge board,
adds a rotation and
probably the center of rotation is not fine ... I' m
going to investigate a
bit more if this depend on import or export or on my
calculations...
2. about the rendering of wrl model SIL7, which version
of FC did you use
to export it?
I tried your wrl in kicad and is not well displayed,
then I exported the
STEP model to wrl in FC 0.15 and the rendering is fine...
I will post the wrl model when I'll be back home.
Thank you again for your feedback
Maurice

This should work, see attached a test board

The SIL7 model is awful, somehow it looks ok in
freecad and really bad
in
kicad.
