The work introduces modeling in AutoCAD as one of the most adapted CAD for professional designers and architects, as well as for beginners. The creation of associative drawings of a building object in AutoCAD based on its 3D model is considered. When developing a building model, the technology of 2D block parametrization was applied, an associative array was used and both solid and surface modeling were implemented. The article introduces the possibility of creating a 3D dynamic block based on associative surfaces in an environment of flat parameterization of AutoCAD. The great importance of organization of work "on layers", with blocks, was noted. The photorealistic visualization of the building and its section with staging the scene was performed: by creation of light sources, assignment of materials, construction of shadows and insertion of a background. The article familiarizes construction students and design engineers with progressive methods of work in AutoCAD while developing the graphic part of the architectural and construction project, which allows one to speed up the implementation of all design processes.
