In article results of work on parametrization blades the compressor of 7 steps of engine NK 14 ST are resulted. The program on creation macros for formation 3D is submitted to model to a feather blades. Areas of use of results of work are discussed.</p>Modelbladeparametersprogramsolid modeling3D-parametrizationМодельлопаткапараметрыпрограммаобъемное моделирование3D-параметризация
