The authors provide a brief description of the software algorithm designed to automatize some of the final stages of design and research into buildings and structures, namely, computer-aided realistic visualization of a simulated object in the AutoCAD environment. Special attention is driven to realistic shadows that are important whenever a construction site is positioned within the environment. The software simulates sunlight by creating a remote source of light. Diffused light is generated by a set of three additional sources of light. The software algorithm is based on a pattern of light sources simulating sunlight and skylight. The point of location of each additional source of light is pre-set by the software operator. This point is identified by the software as the set of coordinates calculated using a special subroutine. The article has a table of sun angles for any time of the day and each month of the year at the latitude of Moscow.

The article describes the issue of increasing the visibility of technological solutions in organizational-technological design. The ability to visualize the main stages of building process technology contributes to organic integration of all the requirements. A special role for the harmonious perception is played by correct display of the lighting facilities, shadowing. Realistic shadows help to analyze the rooms’ insolation of the designed fa- cility and the surrounding areas. We give a justification for the use of AutoCAD in order to automate the process of visualizing the results of organizational-technological design. The author describes the methods of obtaining realistic natural lighting in AutoCAD without significantly increasing the complexity of the process. Engineering companies in 46 % of cases use the software AutoCAD in order to create construction plans. AutoCAD has a variety of possibilities and is constantly evolving. Continuation is one of the benefits of this program. AutoCAD is unique in terms of customization, because, apart from instruction languages, it has two built-in programming languages: AutoLISP and VisualBasic. Because of these specific features AutoCAD allows to create any applications related to graphics implementation. Constant monitoring of lightning changes allows finding the appropriate in terms of aesthetics, ergonomics and insolation decisions on planning and associating a building or structure to the environment. Solar lighting is simulated by a combination of several directional lightning point sources. The author offers a brief description of the program algorithm, which allows automatically managing lighting settings and creating a file with a realistic visualization of the design solutions.
