Review: The subject of this article is the application of the apparatus of set-theoretic operations for the formation of the assembly graph of the construction of the 3D object. The article also considers organization of algorithmic and program electronic constructor of the graph of the 3D object assembly system as one of the ways of transforming archives of design documentation from paper representation to the electronic model of the object. Automation of this process is of great scientific interest and is in the process of developing some scientific geometric schools including the Nizhny Novgorod school. In the research the authors used theoretical and empirical methods: analytical generalization and systematization of information on literary and other sources, the formulation of the problem, the identification and resolution of contradictions, the use of the heuristic approach in constructing working hypotheses, the application of methods of geometric modeling. Automation of data conversion process from 2D to 3D, drawn images into the electronic product model known as the "solution of the inverse problem of descriptive geometry" has long attracted researchers but has not yet been introduced in any of the known geometric modeling systems. The study and analysis of the user's actions, when allocates elementary bodies in the drawing allows to develop the perfect algorithm of "automatic reading of the drawing" with maximum consideration of the heuristic component of this process. The program complex developed by the authors of the article is one of the preparatory stages for conversion of archives of drawn design documentation of the products from paper into electronic form and transformation of a 2D drawing into an electronic three-dimensional model of an object. It also allows conducting practical research in a poorly studied area of human perception of drafting documentation which is necessary for the preparation of software developers for CAD systems.
