System and method for detecting shaping

This disclosure relates to systems and methods for automatically detecting three-dimensional shaping in a three-dimensional model of a sheet-metal part. Therein, data of a three-dimensional model of the sheet-metal part, which extends in a plane spanned by a first direction and a second direction, is detected, wherein the sheet-metal part comprises a bulge in a third direction which is different from the first and the second directions. Then, a horizontal cut is made through the bulge, as well as a vertical cut perpendicular to the plane spanned by the directions, so that closed cross-sectional contours of the bulge are formed. After a transformation, e.g., a Fourier transformation, of the cross-sectional contours, a tool that produces the bulge can be allocated to the Fourier coefficients.
