The modeller is further applied to garment pieces in contact with a mannequin to compare drape with and without constructional features. An energy based modeller, developed for drape simulation, is introduced and applied to model garment constructional details in fabric test specimens of variable stiffness. Features which occur in block patterns and for which accurate simulation is required are identified.
