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! -jelle On Wed, Dec 29, 2010 at 2:44 PM, Petar <petar.peri...@cadcam.hr> wrote: > Hi, > > My name is Petar Perisin, And I'm trying to connect FreeCAD and pythonOCC. > I have posted 2 messages on web site, so here they go: > > Hi, > > I have been playing with this STEP export.
