When determining the buckling modes in RF‑STABILITY, additional lines are displayed for each member perpendicular to the buckling curve. Why?


These lines represent the local torsional rotation (see Figure 01). By default, the torsional rotations φx with the standardized values greater than 0.2 are only displayed. This ensures clear arrangement of the graphic. The graphical display is controlled directly in the add-on module (see Figure 02).
