The "Origamic" approach gives us useful information and suggestion in the design of folding pattern of membrane, which can be applied to retractable membrane roof or foldable membrane structures. In the Origamic approach, membrane is assumed that it has perfect shear rigidity and its flexural deformation occurs only along the crease line. In the paper extraction of basic folding pattern from eigen modes of bending deformation is firstly proposed. Then the condition of foldability and its applications to the generation of foldable pattern in the finite displacement range are also proposed. Finally the patterns and conditions are examined by folding analysis.
