This paper discusses the issues of mathematical support for the formation of various schemes of complex technical objects for a computer-aided design subsystem. Information is given on the description of the station diagram using finite element methods. On the one hand, it is required that the mathematical model be as universal as possible (cover all types of de-signed schemes), accurate, algorithmically reliable. On the other hand, it is required to ensure the minimum cost of the required memory of com-puter time. These contradictions are eliminated by creating a bank of models. Models are planned from separate modules of structural and basic elements, i.e. from the elements of the third and fourth levels of de-composition. Using an interactive program, points on surface lines and volumes are determined. This operation is simplified by creating a struc-tural model of the scheme of complex technical objects, consisting of separate blocks. The article describes methods of joining surfaces with numerical parametric determination
