+G-code exporter
+===============
+
+Functionality
+-------------
+
+Export file with G-code discribing the generated shape
+
+Inputs
+------
+
+**Layer Height** - List of coefficients for layer height
+**Flow Mult** - List of coefficients for Print speed
+**Vertices** - Main thing The Geometry (can be one or severat pathes)
+
+Outputs
+-------
+
+**Info** - Information for sthetoscope of properties of Gcode - path length, filament extrusion and Extruded Volume.
+**Vertices** - Vertices that will be exported
+**Printed Edges** - Edges will be printed
+**Travel Edges** - Edges not will be printed
+
+Properties
+----------
+
+**File** - Define file in directory, that will be written
+**Continuous / Retraction** - Define would be filament retracted back in to nozzle (some kind of effect)
+**Start** - Starting Gcode before it starts printing
+
+--
+
+**End** - Finishing Gcode after all geometry done (turn back nozzle to home position for example)
+**Export Gcode** - Button to export when all ready
+
+Continuous
+----------
+
+**Filament (Ф)** - Thickness of fliament
+**Nozzle** - Coeffitient of nozzle diameter
+**Print** - Printing Speed general
+
+Retraction
+----------
+
+**Filament (Ф)** - Thickness of fliament
+**Nozzle** - Coeffitient of nozzle diameter
+
+--
+
+**Print** - Printing Speed general
+**Zlift** - Lift when retract
+**Travel** - Travel when retract
+
+--
+
+**Retraction** - Itself parameter
+**Z Hop** - Hop after retract
+**Preload** - Load after retract action done
+
+--
+
+**Sort Layers (z)** - Sorting if input geometry have some disorder
+**Close Shapes** - Close all layers
+
+Example of usage
