You must often define the orientation of stiffener profiles. A profile has a linear or twisted orientation and can be divided into multiple regions, each having a different orientation. The following options are available to define profile orientation:

 Rule Region Definition

Defines regions along the profile landing curve. Each region of the landing curve can have a different orientation rule assigned to it. The software initially defines a region boundary point at the profile boundaries. You cannot delete or modify the software-defined region boundary points. You can define and modify additional region boundary along the profile landing curve using grid/reference planes.

 Orientation Rule Assignment

Opens a list of orientation rules from which you can select. These rules include:

  • Normal - The web of the profile follows the plate system surface normal along the landing curve. This is the default setting if the profile parent is a plate system.

  • Up-Down - The orientation vector of the profile cross-section remains in an up-down direction. For example, you can select Up-Down for profiles on a deck.

  • Fore-Aft - The orientation vector of the profile cross-section remains in a fore-aft direction. For example, you can select Fore-Aft for profiles on a transverse frame.

  • Port-Starboard - The orientation vector of the profile cross- section remains in a port-starboard direction. For example, you can select Port-Starboard for longitudinal stringer profiles.

  • Planar - The orientation angle remains constant relative to a reference plane that you specify.

  • Angle - Type the angle for the plane.

  • Reference - Select the reference plane from which to measure the angle. You can select Normal, Up-Down (horizontal), Fore-Aft (longitudinal) or Port-Starboard (transverse). Normal reference plane is the plate system surface normal along the landing curve and is available for any profile orientation. Up-Down, Fore-Aft or Port-Starboard are available as is appropriate for the direction of the landing curve.

  • Plane - Select the plane in which to measure the angle. For Normal Reference, this option is unavailable because the angle is always measured in a plane normal to the landing curve. For Up-Down or Port-Starboard Reference, you can select Normal or Orthogonal. If Normal is selected, the angle is measured in a plane normal to the landing curve. Orthogonal is the transverse, longitudinal or horizontal plane closest to the landing curve normal. If Orthogonal is selected, the software selects the orthogonal plane based on average direction of the landing curve.

Twist Linear Girth

Twist is distributed evenly along the girth length of the profile region, based on the difference between the First Angle and Second Angle defined at each end of the region. The twist rate is constant.

  •  First Angle - Type the angle at the first (beginning) point of the region boundary.

  •  Second Angle - Type the angle at the second (end) point of the region boundary.

  • Angle - See the definition and graphic for the Planar orientation rule.

  • Reference - See the definition and graphic for the Planar orientation rule.

  • Plane - See the definition and graphic for the Planar orientation rule.

Twist Cubic

Twist is distributed using a cubic equation along the girth length of the profile region, based on the difference between the First Angle and Second Angle defined at each end of the region. The twist rate at the ends is zero. The twist rate reaches its maximum at the midpoint.

  •  First Angle - Type the angle at the first (beginning) point of the region boundary.

  •  Second Angle - Type the angle at the second (end) point of the region boundary.

  • Angle - See the definition and graphic for the Planar orientation rule.

  • Reference - See the definition and graphic for the Planar orientation rule.

  • Plane - See the definition and graphic for the Planar orientation rule.

Twist Linear Ortho

Twist is constant at every frame along the orthogonal projection length of the profile region, based on the difference between the First Angle and Second Angle defined at each end of the region. The software uses the Main_CS frame system if it exists. Otherwise, the software uses the CS_0 frame system.

  •  First Angle - Type the angle at the first (beginning) point of the region boundary.

  •  Second Angle - Type the angle at the second (end) point of the region boundary.

  • Angle - See the definition and graphic for the Planar orientation rule.

  • Reference - See the definition and graphic for the Planar orientation rule.

  • Plane - See the definition and graphic for the Planar orientation rule.
