What do the nine points refer to when considering any cross-section (Z-Section) in the RF-/STEEL Warping Torsion?

Answer

The setting of the load application in the Details refers to the principal axes of the respective cross-section. For a Z-Profile as an example, a box with the nine edge nodes is put around the profile. The load application is then always related to the rotated principal axis angle and the corresponding eccentricities.
