**Planes** | Pl | Set of planes on surface to tween through | Plane |

**Surface** | S | Surface to tween plane on | Surface |

**Factor** | F | Tween factor (0.0 = Plane at Pl start, 1.0 = Plane at Pl end), unless Normalized is False | Number |

**Normalized** | N | If False, the rules for factor are (0.0 = Plane at index 0, Index number of last plane = Plane at last index)
The tween factor range from one plane to the next plane in the list is:
Index number of a plane = the plane at that index, Index number of the next plane = the next plane in the list, factors between the plane index numbers will be the corresponding tweens.
For instance:
A tween factor of 2.5 will result in a tween plane halfway between the plane at index 2 and the plane at index 3. | Boolean |

**Equalized** | E | If True, tween distribution is evaluated along the tween path without considering the locations of the input plane set | Boolean |

**Weighted** | W | If True, tween distribution is weighted by the input plane set and the tween path curvature | Boolean |

**Loopback** | L | If True, allow the tween path to continue from the end back to the start as a closed loop
(if Normalized is False, increase the tween factor range maximum by 1) | Boolean |

**Degree** | D | Curvature degree of the tween path, degree should be a positive odd number | Integer |

**Interpolation Type** | I | Determines how the tween path is interpolated
0 = Linear
1 = Chord
2 = Square Root
3 = Uniform | Integer |

**Quaternion** | Q | Interpolate with quaternion rotation | Boolean |
