FORMFINDING: TENSILE SURFACE STRUCTURE
FEST.EIN coordinates of fixed points RANGENN.EIN fixed points: 3D-coordinates + fixity status boundary cable points: 3D-coordinates + fixity status cable links: length, force density, stifness
NETGENN.EIN (2D) fixed points: 3D-coordinates + fixity status boundary cable points: 3D-coordinates + fixity status net points: 3D-coordinates + fixity status cable links: length, force density, stiffness
LAGGEN.EIN like NETGENN.EIN but including T-elements ZUSN.EIN (3D) RANGENN.EIN + NETGENN.EIN in 3D FOFIN.EIN Formfinding result LOOP2D.ECK Polygons LOOP2D.DRE Triangles
