| Method |
Sets the spiral's mathematical definition.
- Clothoid — Used to create a smooth transition between arcs that have different radii so that there is no abrupt change of curvature. Used in highway design.
- Archimedes — The radius changes linearly based on the angle.
- Logarithmic — The radius changes exponentially based on the angle.
|
| Initial Degree |
(Type set to Clothoid only) Sets the degree of curvature at the origin. |
| Final Degree |
(Type set to Clothoid only) Sets the degree of curvature at the spiral's endpoint. |
| Length |
(Type set to Clothoid only) Sets the spiral's length. |
| Initial Radius |
(Type set to Archimedes or Logarithmic only) Sets the radius at the origin. |
| Final Radius |
(Type set to Archimedes or Logarithmic only) Sets the radius at the spiral's endpoint. |
| Angle |
(Type set to Archimedes or Logarithmic only) Sets the sweep angle. |
| Tolerance |
(Type set to Clothoid or Logarithmic only) Sets the tolerance. |
Used to place a transitional spiral as a B-spline curve.
