I cannot define the prestress separately for warp and weft in RF‑FORM‑FINDING. How can I activate it?


The warp and weft directions are linked to the axes of the surface. The default setting allows you to only apply isotropic prestress. If the axes are aligned, the orthotropic or radial prestress will be available as well.

The video shows the procedure.
