This paper discusses the problems of form finding and production of cutting patterns for fabric tension strictures. A computer method is proposed for simultaneous form finding and cutting pattern generation which produces initial principal stresses in the directions of the warp and weft of the fabric. A large‐displacement finite element procedure for computing the initial equilibrium shapes of tension structures is presented Several variations on this basic method are suggested. The cutting pattern generation method is based on the finite element model. A weighted least‐squares minimization flattening approach is developed to minimize the change in general link lengths and to generate plane cloth coordinates. Some design examples are given.
