If I understand correctly, in the above implementation I cannot define firstly a (non-oriented) body, and then build, on top of it, two bodies with opposite orientations.

The above comments apply here, too. In what concerns other suggestion, about Python language, I shall do my best to understand them and apply them. Thank you.
