Curved Stiffeners

By definition a curved stiffener has a trace curve that is not straight. On the other hand the cross section perpendicular to the trace curve is always constant and equal to the nominal dimension of the profile.

This means that a stiffener which is knuckled perpendicular to its trace is a curved stiffener, not a knuckled stiffener, see the image below.

Curved stiffeners may be set parallel to limits, holes and arbitrary curves stored in the panel.
