Fairing types

Hull line points are connected by a 2D curve (fairing). In order to obtain the desired curve, the user can influence the fairing type and/or the fairing direction at every point.

In this chapter you can read more details about the available fairing settings of your hull points.

The following fairing types are available:

Faired

The 2D curve is continuous and is automatically faired through the hull line points.

The image below shows a hull line where all points are set as faired.

Faired with direction

The 2D curve is continuous and the angle of the hull line at the selected point is defined by a specified direction for both incoming and outgoing directions.

The image below shows a hull line where the second point has been faired with direction to baseline.

Knuckle

Breaks the curve of the fairing at the selected point. Both incoming and outgoing directions are determined automatically. The image below shows a hull line where the second point has been faired with a knuckle.

The option Radius can be used in two ways:

  • If the hull line consists of a single point, then the radius is used to construct a 2D circle. The single point is the circle's centre point.
  • If several points are defined, the radius is used to construct a rounded corner.

    The radius is not applied when:
      • the connected curve segments are not straight lines.
      • the angle between the straight line segments is 0 or 180 degrees.
      • the radius introduced is larger than the maximum value allowed by the geometry.

Knuckle with incoming direction

Breaks the fairing at the selected point. You have the chance to define the direction type of the incoming direction at the selected point. The outgoing direction is determined automatically, based on the direction of the following point.

Knuckle with outgoing direction

Breaks the fairing at the current point. You have the chance to define the direction type of the outgoing direction at the selected point. The incoming direction is determined automatically, based on the direction of the previous point.

Knuckle with directions

Breaks the fairing at the current point. The direction types for both the incoming and outgoing directions must be specified.
