This paper discusses on the numerical model flattening algorithms enabling the representation of straightened surface of three-dimensional objects in the plane. These algorithms are widely used in the engineering industry which requires a precise representation of surfaces of various fragments of 2D maps, such as the automotive industry. One of the examples of the application in the manufacture of footwear could be automatic formation of molds using shoetrees, which are usually produced by a unit ignoring the fact that manufacturers are still using wax foil for flattening. This paper provides an investigation of the most widely used 3D object surface flattening algorithms and also the comparison of molds of shoetrees obtained by these methods.
