17 | private class ApproxSeewing from BRepFill |

18 | |

19 | ---Purpose: Evaluate the 3dCurve and the PCurves described in |

20 | -- a MultiLine from BRepFill. The parametrization of |

21 | -- those curves is not imposed by the Bissectrice. |

22 | -- The parametrization is given approximatively by |

23 | -- the abscissa of the curve3d. |
