Hi jelle
I have seen this example, and it does not generate any file in my
installation of pythonOCC (I have tried to make filename
"C:\Users\Petar\Desktop\result_export_multi.stp". It is probably because
in my installation there is no "my_step_exporter.write_file()" command.
I have only "my_step_exporter.write()" (I have installation from the web
- all in one version 0.4 with python 2.6 for windows). But even after
modifying this I don't see result_export_multi.stp file on my desktop.
But, could you do me a favor? Can you please make cut of this two shapes
from the example (cube and sphere), export resulting shape in green, and
put a STEP file on web page so that I can check it out?
Regards,
Petar Perisin

Hi Petar,
3 links:
1) use
StepOCAF_Export<http://code.google.com/p/pythonocc/source/browse/trunk/src/addons/Utils/DataExchange/STEP.py?r=1115>
it
supports colors& layers ( not all readers support 'em rhino does... )
2) here's an
example...<http://code.google.com/p/pythonocc/source/browse/trunk/src/examples/Level2/DataExchange/export_multi_to_step_colors_layers_ocaf.py?spec=svn1115&r=1115>
<http://code.google.com/p/pythonocc/source/browse/trunk/src/examples/Level2/DataExchange/export_multi_to_step_colors_layers_ocaf.py?spec=svn1115&r=1115>3)
use
OCC.Utils.Construct<http://code.google.com/p/pythonocc/source/browse/trunk/src/addons/Utils/Construct.py?r=1115>to
make your code much more pythonic.
Happy to have you on board.
FreeCAD is a great project& the link with pythonocc is terrific work!
