Knuckles are created automatically as children of extruded plate systems and of profile systems by projection when there is an acute discontinuity (an angle with no radius) on the extrusion or landing curve. These knuckles can be modified through the dialogs shown below. Profile knuckles can also be added manually.
You can change the default colors of knuckle curves, seams, profile systems, and reference curves to enhance visibility. See Modify Plate Knuckle Curve Display Colors.
