In order to carry out the work, a topographic survey of the site was necessary at a scale of 1: 2000, and for the radiated points the rectangular coordinates were calculated in STEREOGRAPHIC 1970 system, and then with their help the plan and analytical calculation of the surface were drafted. Specialized programs were used to calculate the rectangular coordinates and the analytical calculation of the surfaces, and the data will be loaded and then processed in AutoCAD. AutoCAD is a CAD program used in the design of construction plans in two dimensions (2D), less in three dimensions (3D), developed and marketed by the American company Autodesk. The system-specific ('native') files are the dwg type, as well as the dxf (Drawing eXchange Format) files, which are extremely widespread. Although it was originally created to run on platforms such as Unix and Macintosh, its development was abandoned in favor of the Windows operating system. AutoCAD - computer aided design - is the most common environment for computer aided graphics and design, successfully used in fields such as architecture, geography, medicine, astronomy, technology, etc. The Hi-Target V30 GPS was used to make the measurements, angles and distances.
