Process for generating a multidimensional offset surface with a predeterminable distance (d) from a starting surface (10, 20) of the same dimensions, wherein in order to generate a point on the offset surface (10'') (offset point) an approximation normal (ND) is determined, which stands perpendicular to an approximation surface the position and course of which correspond approximately to the position and course of the starting surface (10, 20), the approximation normal (ND) forming a point of intersection (S3) with the starting surface (10, 20) which forms the point of the starting surface (10, 20) relative to which the associated offset point is to be generated, and the offset point is generated along the direction of the approximation normal (ND) starting from the point of intersection (S3) at a distance corresponding to the given offset distance (d), while a plurality of offset points obtained in this way serve to form the offset surface (10'').
