Computer techniques for the generation of cutting patterns for membrane structures are reviewed. The two types of design systems under review are based on the dynamic relaxation and force density methods. With the dynamic relaxation system a geometric unfolding method is used to generate cutting patterns, whereas with the force density system a least squares minimization procedure is used to generate the cutting pattern. A new procedure for generating cutting patterns, using a two-dimensional dynamic relaxation analysis for each cloth, is proposed. Comparisons are undertaken for a standard test case and reassembled cloth strips are re-analysed and variations in stress compared. © 1990.
