## 1.3. Communication with other engineering software

The base drawing (plans of individual storeys), which is necessary for designing radiant heating system and is also used to calculate heat losses, may be drawn directly in the application, or may be imported from one or more DXF or DWG files created with engineering graphical software. The files may be imported with or without having the walls, windows and doors interpreted. In the first case the individual objects are recognised and rooms will be defined. In the latter case the imported material will form just a background drawing on which the plan may be drawn. In order to enable proper interpretation of the file and identification of walls, windows and doors and creation of rooms, it is important that defined principles of graphical design are observed within the application where the building design is created. These principles are described further in this manual.

When plans and drawings and calculations of the system are complete, the drawings with calculation results may be printed, or saved (exported) to DXF or DWG files. These files may include just the base drawing and the system, or the export may comprise the remaining contents of the DXF or DWG files from which the plans were imported, and then new layers will be appended with the components designed. This way the documents created may be adapted to a specific standard, where all graphical information (including other system drawings) is included in one DWG/DXF file.
