    The ending point of a curve is the starting point of the next curve in the

    Parameters
    ----------
    self : HoleM54
        A HoleM54 object
    alpha : float
        Angle to rotate the slot (Default value = 0) [rad]
    delta : complex
        Complex to translate the slot (Default value = 0)
    is_simplified : bool
       True to avoid line superposition
