Zusammenfassung:	The invention relates to a method for controlling the conformity of a profile of a section of a curved surface of a turbomachine element, comprising the following step: -(100) acquiring coordinates of a plurality of measurement points of the section in a frame of reference defined for said section; characterised in that the method comprises the following steps: -(200) calculating, based on the coordinates of these measurement points, the radius of curvature of the section at each of these points, in order to obtain a measured evolution curve of the radius of curvature according to the position of the measurement points along said section; -(300) comparing the measured evolution curve of the radius of curvature, obtained in the preceding step, with a theoretical evolution curve of the radius of curvature of the predetermined section; -(400) evaluating the conformity of the section based on the comparison carried out in the preceding step.
