FAQ: What are the curve and tangent curve parameters for the Traverse tool?

Question

What are the curve and tangent curve parameters for the Traverse tool?

Answer

For a tangent curve there are four parameter types:

- Chord: Length of the chord of the curve.
- Angle: Internal angle of the curve.
- Arc: Length of the arc of the curve.
- Radius: Radius of the curve.

Turn specifies whether the course is curving to the left or to the right.

For a nontangent curve, the parameters also include:

- Chord Direction: Direction of the chord of the curve.
- Radial Direction: Direction of the radius of the curve, taken at the start point.
- Tangent Direction: Direction of the tangent of the curve, taken at the start point.
