Specifies the position of the profile cross-section.

Primary Orientation

Specifies the side of the plate system used to place the stiffener profile. The default setting is determined by the molded conventions of the parent system. This property can be modified only at the root system.

Secondary Orientation

Specifies the direction of the web thickness for symmetrical cross-sections and the direction of the flange and web thickness for unsymmetrical cross- sections. The default setting is determined by the molded conventions of the parent system. This property can be modified only at the root system.

Mounting Face

Specifies the cross-section face to mount to the plate system. The options vary depending on the profile cross-section.

Load Point

Specifies the cross-section load point through which the landing curve passes.

Landing Curve Projection Method

Specifies how the software locates the landing curve with respect to the parent plate system thickness. The list is defined by the ShipStructLandingCurveProjectionMethod codelist

Along Web indicates that Smart 3D projects the landing curve in-line with the profile web.

Normal indicates that Smart 3D projects the landing curve normal to the plate surface.

Attachment Method

Specifies the method of trimming the profile web where it is attached to the plate system. The list is defined by the ShipStructStiffenerAttachmentMethod codelist.

Partial Trim indicates that Smart 3D trims the short side of the web.

No Trim indicates that Smart 3D does not trim the web.

Full Trim indicates that Smart 3D trims the entire web.

Offset Method

Specifies how the profile is offset from and trimmed by the plate system when the profile crosses design seams with leaf plates of varying thickness, and the profile is on the thickened sides of the plates. The list is defined by the StiffenerOffsetMethod codelist.

Position on thinnest plate indicates that each profile part of the parent profile system is mounted to the thinnest plate part that the profile part crosses. The profile part is then trimmed to any thicker plate it crosses.

Position on thickest plate indicates that each profile part of the parent profile system is mounted to the thickest plate part that the profile part crosses. No trimming occurs.

Offset and trim indicates that each profile part of the parent profile system is mounted at the specified Offset Value from the molded surface of the plate system. Profile part position is not adjusted based on plate part thickness. Each profile part is trimmed by any plate part thicker than the offset distance.

Offset with no trim indicates that each profile part of the parent profile system is mounted at the specified Offset Value from the molded surface of the plate system. Profile part position is not adjusted based on plate part thickness. Profile parts are not trimmed by any plate part thicker than the offset distance.

This option is useful when the gap from successively thicker plates can be filled by welding:

Offset Value

Specifies the amount of offset used with Offset and trim or Offset with no trim. A positive value moves the stiffener away from the molded surface. A negative value moves it toward the molded surface. The value is also relative to the profile orientation.

For example, the following positive and negative values are used when profile orientation is Below on a deck:

The following positive and negative values are used when the profile orientation is Above on a deck:

Attachment, connection, and offset methods are applied to the profile after the plate and profile systems are detailed in Structural Detailing.

Start Connection Method

Specifies the method of connecting the beginning of the profile to its plate, profile, or member boundary. By Rule is the default setting. The connection is determined by assembly connection rules defined for Structural Detailing. Other connection methods can be added as part of your reference data customization.

Welded

Places a welded web and flange cut.

Snip

Places a snipped web and flanged cut.

Cutback

Places a web and flange cut that are straight (not snipped) but are cut back from the bounding object.

Bracketed

Places a bracket as a child of the assembly connection.

End Connection Method

Specifies the method of connecting the end of the profile to its plate, profile, or member boundary. By Rule is the default setting. The connection is determined by assembly connection rules defined for Structural Detailing. Other connection methods can be added as part of your reference data customization.

Identifying Parent Values for Leaf Properties

For a property on a leaf system, the value assigned to the root system contains an asterisk (*), such as:

This makes it easy to see whether the currently assigned value for a leaf property is different from the parent property. You can also change a modifiable leaf property back to the root value without first checking the root value in the root system Properties dialog.

The asterisk (*) only displays in the Properties dialog for a leaf system.
