Displays the options that you use to place a stiffener profile in the model.

 Profile by Intersection Settings - Opens the Profile by Intersection Settings dialog box, which you use to view and modify the properties of the profile system that you are about to place in the model. The initial settings default from the parent plate system. For more information, see Profile Properties Dialog Box.

 Plate System - Specifies the plate system that you want to stiffen. You can select multiple plate systems to place multiple stiffener profiles systems at the same time. The software uses the same information for each stiffener profile system. After placement, the stiffener profiles are unrelated to each other and can be edited as individual entities.

 Landing Curve Definition - Specifies the grid planes that intersect the plate system at which to place the stiffener profiles.

 Profile Orientation Definition - Defines the orientation of the profile system cross-section. See the Profile Orientation Definition Controls section below.

 Boundary Definition - Defines the boundaries of the stiffener profile. You can define the boundaries by selecting objects in the model. If you select objects in the model and those objects are moved, the software automatically resizes the stiffener profile to maintain the boundary relationship. See the Boundary Definition Controls section below.

Finish - Places the stiffener profile using the defined parameters.

Profile Orientation Definition Controls

Available when you use the Profile Orientation Definition option.

 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.

 Profile System Table

Opens a read-only table containing the coordinates, orientation angles, and twist rates of the current profile.

Boundary Definition Controls

Available when you use the Boundary Definition option.

Pick Boundaries

Selects objects in the model or in the Workspace Explorer to define the boundaries. This option is only available when you are defining the boundaries.

After you select a boundary plate, press SHIFT to select the Pick Edges option. Press SHIFT again to return to the Pick Boundaries option.

Pick Edges

Selects free edges on plates to define the boundary. This option is available when you select a plate in the Pick Boundaries step.

 Solve Ambiguity

Clarifies the required boundary. If the boundaries that you selected can form the object boundary in more than one way, then you have defined an ambiguous boundary. The software prompts you to select multiple bounded areas to specify the boundary. For more information, see Solve ambiguous solution created by selected boundaries.

 Boundary List

Opens the Boundary List dialog box. This dialog box allows you to review and define the boundaries. For more information, see Boundary List Dialog Box.

 Boundary Curve

Draws the boundaries. This option is only available when you are defining the boundaries. See Define Plane Controls below.

Sketching Plane

Selects the sketching plane for the boundary.

Add Intersecting Item

Allows you to select objects in the model that intersect the sketching plane to use as reference geometry. You see the selected objects in the Sketch 2D environment.

Add Projection Item

Allows you to select objects in the model that do not intersect the sketching plane that you want to use as reference geometry. The objects are projected onto the sketching plane, and you see the selected objects in the Sketch 2D environment.

Sketch 2D

Opens the Sketch 2D environment in which you can draw the boundary.

Auto

Allows the software to automatically add all objects that are relative to the object to be sketched to a select set. The Workspace Explorer and the graphics view highlight items in the select set. If the software adds no objects to the select set, a message displays in the status bar. This option is only available when you use the Add Intersecting Item or the Add Projection Item option. For more information, see Sketch 2D Best Practices.

 Reject - Clears all selected objects.

 Accept - Accepts all selected objects.

Section Type - Specifies the cross-section type for the profile.

Section Size - Specifies the cross-section size for the profile.

Name - Displays the name of the stiffener profile that you are placing.
