[Bruno Chareyre <bruno.chareyre@xxxxxxxxxxx>]

Thank you for notifying and fixing the error.
I see SpherePack_toSimulation has a feature that I did not suspect (and
that I find in fact annoying): it sets the cell's size to the packing's
size (which means I can't generate a cloud smaller, or with a different
geometry, than the cell itself).
Commenting  the line blocked this behaviour, hence was detected by some
doc-testing (pack.py:73):

Add generated packing to the simulation, rotated by 45° along +z

    >>> sp.toSimulation(rot=Quaternion((0,0,1),pi/4),color=(0,0,1))
    [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19]

Periodic properties are transferred to the simulation correctly,
including rotation:

    >>> O.periodic
    True
    >>> O.cell.refSize
    Vector3(5,5,5)
    >>> O.cell.hSize
    Matrix3(3.53553,-3.53553,0, 3.53553,3.53553,0, 0,0,5)

It is ok to revert the change and keep the line uncommented as you did.
Fortunately, I think there is a workaround to avoid modifying the cell.

Bruno
