Profile Knuckle Properties

Displays the Manual Profile Knuckle Properties dialog box, which you use to view and modify the properties of the knuckle. For more information, see Profile Knuckle Tab (Manual Profile Knuckle Dialog Box).

Select Profile System

Specifies the profile system on which you want to place a manual knuckle.

Reference Curve

Specifies the reference curve, which you want to use to place a manual knuckle. You can select only one reference curve.

Generate Knuckle Point through GC

Allows creation of a geometry construction point to use as the reference to place the manual knuckle. You create the geometry directly in a graphic view by using the Geometric Construction Palette dialog box, the Geometric Construction ribbon, and the Geometric Construction Explorer. This option is the 3D equivalent to Sketch 2D. For more information, see Geometric Construction Palette Dialog Box and Geometric Construction Explorer Dialog Box.


Places the manual knuckle using the reference you chose.

Manufacturing Method

Specifies the default manufacturing method for the manual knuckle. Select one of the following options:

  • Split - The knuckle point behaves as a design seam. You must run Execute Split 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. For more information, see Execute Split.

  • Ignore - The profile part is not affected. The knuckle point is ignored and no knuckle is created.

  • Extend - Allows the tangential extension of the profile beyond the profile seam. The Structural Detailing task determines part geometry and applicable end cuts.

  • Split and Extend - Allows the profile system to split at the knuckle, and also at the tangential extension of the part beyond the knuckle.


Splits the profile system when Finish is clicked.

If this option is not selected, click Execute Split to split the profile system. For more information, see Split a profile or member system.
