VRML scaling works great using
freecad your_part.step kicad_StepUp_vrml_export.FCMacro
The parametric generator gives me the following error:

Hi Marcos,
thank you for the feedback.
The screenshot is very nice!
1) For fusion object, it is strange, I don't have prob in conserving
colors neither in FC015, nor in FC016 both in win and linux...
but I'm on ubuntu and I used the ubu repos
2) To scale a part there is already a small macro in the demo project;
the file name is kicad_StepUp_vrml_export.FCMacro
and there is also a bash file
launch-kicad_StepUp-step-to-vrml-example.sh
The script has to be cleaned up a bit...
anyway it works... NB after exporting the VRML file, do not save the
FC STEP file or you'll get it scaled too :)
3) I'm going to complete a new macro named 'move_rotate_scale'
(which is not included at the moment), so it would be easier to
manage manufacturer models to align and generate vrml scaled models.
When it si ready I will let you know
4) Please also have a look at:
https://github.com/easyw/kicad-3d-models-in-freecad/tree/master/cadquery/FCAD_script_generator
there are script to generate parametric STEP and scaled VRML for
SOIC, DIP, QFP, Resistor chips and Capacitor chips
there are some configuration files in which you only need to add
dimensions as in the datasheet, then the model 3D will be generated.
There a re also some already generated examples at:
https://github.com/easyw/kicad-3d-models-in-freecad/tree/master/cadquery/FCAD_script_generator/generated_cap
https://github.com/easyw/kicad-3d-models-in-freecad/tree/master/cadquery/FCAD_script_generator/generated_gw

https://github.com/easyw/kicad-3d-models-in-freecad/tree/master/cadquery/FCAD_script_generator/generated_res
and a mini starter guide
https://github.com/easyw/kicad-3d-models-in-freecad/raw/master/cadquery/FCAD_script_generator/FC-script-generator-starter-Guide.pdf
I've added a colored pinmark and some more models.
Could you please give me a feedback also on those scripts/models.

Hi Maurice,
the issues were related to using freecad 0.16 and non compatible
DXF files
(Freecad 0.15 and 0.16 produced an incompatible dxf file that
was fixed
re-exporting it using librecad in R14 format, later you told me
that R12 is
better but I didn't try.
The final woraround for fusing parts and maintaing the color
correctly was
to make the top level fused part 100% transparent It seems that
when I
export the fused part freecad exports all the parts inside the
fusion too,
and the object surfaces have all 2 faces, one from the fused and
one from
the original, and the colors get messed up. Forcing the fused part
transparent it still exports duplicated faces but since one is
transparent
it doesn't bother me. Maybe it a dependency issue when compiling
FC15 and
this doesn't happen in a stable FC installation.
BTW, now it is *much* easier to import 3D parts from the
manufacturers 3D
models

I'll share the footprints when I get some free time, have to
organize them
and make a repo for it. Oh and I have to learn to scale the parts by
1/2.54. How do you scale them? it seems MCAD don't like to just
shrink a
part.
There is an Draft.scale() function call in your script, does it
work with
raw STEP files?

Marcos
