Specifies the properties of the profile knuckle.


Specifies the name of the knuckle. Names generated by a rule include a Global Workshare name rule ID if the name rule ID was defined when the model database was created. For more information, see Using Global Workshare in the Global Workshare Guide.


Select the naming rule to name the knuckle.

Override Rule

Indicates whether you can manually specify the Manufacturing Method. When this option is cleared, the catalog rules determine the behavior of the profile.

Knuckle Properties

Manufacturing Method

Specifies the method for creating the knuckle. This list is only available if the Override Rule check box is selected. The availability of methods depends on the profile cross-section type and the plate seam condition. The list is defined by the ProfileKnuckleManufacturingMethod codelist.

  • Bend indicates that the knuckled part displays the bend radius after detailing. The Flat Bar cross-section type is supported for this option.

  • Split indicates that the knuckle point behaves as a design seam. You must run the Execute Split command to split the profile system. During detailing, the end cut rules determines the part geometry. The plane bisecting the knuckle angle is passed to the end cut rules. All cross-section types are supported.

  • Ignore indicates that no seam or radius is created. This applies to EA, UA, BF and Flat Bar cross-section types. This option is available when the knuckle angle is 2° or less.

  • Extend indicates that the tangential extension of the profile can extend beyond the profile seam. The software determines part geometry and applicable end cuts. The profile is trimmed to the plate contours after detailing. All cross-section types are supported.

  • Bend Plus Feature indicates that when a profile is bent about its weak axis, Smart 3D places a feature or features on a profile after detailing. The resulting features that are placed are based on a combination of the profile knuckle rule and the smart occurrence rules. For example, an edge feature and an insert plate feature are placed on a profile that has a concave bend with its flange oriented on the convex side. This applies to UA and EA cross-section types with heights of 200 mm or more and knuckle angles of 90° or less.

Inner Radius

Specifies the inner radius dimension of the knuckle. The inner radius is generally two times the web thickness. This box is read-only if Override Rule is cleared.

Outer Radius

Specifies the outer radius dimension of the knuckle. The outer radius is generally the inner radius plus the flange length. This box is read-only if Override Rule is cleared.

Knuckle Angle

Displays the angle of the knuckle bend.

Related Plate Knuckle

Displays the name of the associated plate knuckle.
