Dear Jelle,
as a new user of pythonocc I installed it on suse-linux and would like to try
your example regarding the spline approximation, but with you code I got the
following error message (your code is included in the file 'naca.py'):
Could you please give me a hint for exporting the spline into a step file - my
goal would be the creation of a 3D-type structure like Marcos is trying for ?
