1. Yes you were right I commited models without noticing, sorry !
2. I have issues with the previous tests, and would need your help understanding why.

binding/python3/model_creation/segment_real.py line 58 at r1 (raw file):

        if self.rotations != Rotations.NONE:
            out_string += f"\trotations\t{self.rotations.value}\n"
        if self.q_ranges != None:

For very subtle reasons in Python, comparing against None should be done using the "is" operator (instead of the equal operator "=="), as it may leads in some tricky cases to be evaluated as True while False is expected. So this should be changed to:
self.q_ranges is not None

Please change all the occurrences of these (I may have missed some in other files too)

@EveCharbie
It seems the tests were broken by this PR I will wait that it is fixed to merge!
