Answer:
The RF‑/STEEL Warping Torsion add-on module is a module extension of the RF‑/STEEL EC3 add-on module. You can activate RF‑/STEEL Warping Torsion directly in the EC3 module in the details (see the image). The windows are then adjusted accordingly. Since this module is only suitable for sets of members, it is not possible to select any members for the design.
