Gcode is specifically designed for converting AutoCAD drawings into
G-Code files for use with any 2-D or 3-D machine such as wire EDMs,
laser etchers, flame cutting, 3 axis milling machines, lathes etc.
GCode can be used for creating individual complicated tool paths for 2-D
and 3-D machines. Custom INI files are used to tailor Gcode to your
particular machine tool.
TTFtoDXF a utility to convert from a single character to a paragraph of text
in any True Type font, to a Dxf file which can then be manipulated in Gcode
or Autocad. Handy for sign making or engraving.
