hey Marco,
That sounds like a smart idea. I think you've probably got further than
I have. I have OCC6.3.0 installed and running, but I haven't got very
far with pyOCC yet. I'll try and have a go tonight and see where I get
to. I'm building on i386 at home - I have an x86_64 at work, but it
needs a bit of work before I can install there.
Do you have any tips before I start?
