How can I influence the sag of the found shape in RF‑FORM‑FINDING?


The sag can be influenced by the prestress of the membrane. Please note that the uniform increment in both directions does not cause any changes in the shape. Thus, a modification must be made in the desired direction only. The video shows the procedure.
