Abstract. Design is one of the most challenging types of intellectual work. In industrial practice, the object of design automation is a set of actions by a designer who develops a product, the result of which is design and technological documentation. When designing shoes, various design steps are repeated many times. This is due to the fact that design is a naturally developing process, consisting of stages and operations that can be described using certain mathematical methods and determine the tools for their automation. It begins with the development of a general concept of the designed structure — a draft design. The process of developing a draft design in different CAD systems is carried out in different ways. For all stages of shoe design and manufacturing technology, the following basic typical information processing operations can be distinguished:

• search and selection from various sources of the necessary information;

• analysis of the selected information;

• performing calculations;

• making design decisions;

• design of design solutions in a form convenient for further use at subsequent stages of design and manufacture of the product. Therefore, the authors in their decision proceeded from the fact that at the stage of sketch development, one should operate with information that allows for calculations, designed, on the one hand, to increase the objectivity of the design decisions, on the other hand, to ensure digitalization of the Sketch Design module for CAD footwear.

The aim of the study is to link sketch planar design with computer-aided design by establishing a correspondence between the sketch of a part and the outline of this part in the drawing of the structural basis of the upper of the shoe. This will automatically prepare a preliminary drawing of the new model when overlapping parts during the sketching process. The proposed algorithms and mathematical calculations can be used in both 2D and 3D computer-aided design systems. This approach is implemented within the framework of the dissertation for the degree of candidate of technical sciences Razina E.I. and is supposed to be used in the educational process of the departments «Artistic modeling, design and technology of leather goods», «Information technology» Russian State University A.N. Kosygin (Technology. Design. Art).
