**Rail 1** | R¹ | Rail curve that the first and fourth corners of the twisted boxes are on | Curve |

**Rail 2** | R² | Rail curve that the second and third corners of the twisted boxes are on | Curve |

**Thickness** | T | Thickness of the twisted box strip, offset from the rail curves | Number |

**Parameters T1** | t¹ | Division parameters along rail curve one's {t} domain (0.0 = Rail 1 start, 1.0 = Rail 1 end)
For best results parameters should be between 0 and 1, in numerical order, non duplicate, and have the same amount of parameters as the parameters {t} t¹ list | Number |

**Parameters T2** | t² | Division parameters along rail curve two's {t} domain (0.0 = Rail 2 start, 1.0 = Rail 2 end)
For best results parameters should be between 0 and 1, in numerical order, non duplicate, and have the same amount of parameters as the parameters {t} t² list | Number |

**Weighted** | W | If True, parameters {t} distribution is weighted by the input rail curves curvatures | Boolean |
