The authors present the main properties of the planar configuration of Desargues, which open the possibility of its widespread use in architectural design and the design of complex volumes, consisting of a series of simple overlapping forms. However, the computer implementation of Desargues configuration construction is associated with certain difficulties caused by the fact that the monitor can only discretely represent the graphical information. In this article we identified and analyzed the properties of Desargues configuration, the use of which allows overcoming these difficulties and solving the problem of the limited capacity of monitors in the development of complex architectural forms with the help of computer graphics. Along with this, the use of the allocated properties allows predicting complex effects of the perception of architectural forms, for example, the difference of perception of architectural objects near and afar with account for perspective distortion, and they are also the basis for the development of the algorithm of construction sequence during design.

In civil engineering and architectural design the coupling of circular curves are of great importance. There are different requirements for their practical application, including the possibility of approximation of the curves of higher order. The present article contains a brief excursion into the axiomatic description of the properties and concepts uniting the geometric graphics of a circular, a direct and a point into various compositions. One of the main conjunction theorems is presented, which defines the position and properties of orthoelements of pairing and the sequence of mating arcs using symmetry. The content of the theorem is commented in the form of proof by contradiction, in the form of geometric graphical operations that are naturally consistent with the analytical results. The examples are given of the circular conjunctions closed into oval shapes with a slight difference in the algorithms of composition construction. A particular case of the present configuration is a linear model of squaring the circle, the circle when the medial conjunction coincides with the base circle squaring. Here, the rhomb figure is presented as a basic square and the four successively conjugated circles have their centers at the vertices of squaring, their area are equiareals. Then, the straight “tapered” circular number and variations of its geometry graphical construction are analyzed. The summary results of the considered material are as follows. The main qualitative, quantitative, and typical examples of the circular conjunctions allow competently and variably solving certain problems of geometry graphics in the design process of civil engineering, architecture and applied domestic objects, items and personal things.

The article presents the results of the analysis to assess the multi-variant approaches to constructing the Desargues configuration which is the fundamental to projective geometry and projective graphics. From the practical point it is the basis for the theory of perspective and is widely used to solve various tasks, such as constructing shadows in perspective, a direct, incidentally out of the rich within the drawing of the vanishing point, etc. The authors present the algorithm of the possible variants of construction of the Desargues configuration using computer technologies. The computer implementation of theoretical provisions of separate aspects of projective geometry and graphics has previously been considered as applied to Johnson polyhedrons. As any other figure the configuration of Desargues may be constructed by different methods. The authors consider the choice of points and directs included into the configuration and different interpretations of the relations of the point. The considered algorithm of the possible variants of the Desargues configuration construction will allow widely using the configuration in design of complex architectural and design volumes, consisting of a series of simple overlapping forms, by means of modern computer technology.
