    <title>Introduction</title>
    <para>
      The DXF to NGC converter <emphasis>dxfngc</emphasis> provides a
      means to convert 2D technical drawings in DXF file format to G-code
      in NGC format used by CNC mills or routers (e.g. LinuxCNC).
    </para>
    <para>
      Usually, the 2D drawings in DXF format do not contain enough information
      for G-code creation, e.g. about which lines describe the border of a part
      and which lines describe holes.  The diameter of the cutting tool and the
      depth of the cut are other examples.  Therefore, dxfngc relies on a
      script file to control the G-code generation.  This script is the input
      to the tool.  It sets all required parameters, reads the drawing,
      controls generation of the G-code and finally writes the output file.

    <para>
      To illustrate the usage of dxfngc, suppose a stencil for the
      <emphasis>BlinkenArea</emphasis> logo shall be cut with a CNC mill.  The
      basic shape of the stencil is a circle.  The logo is formed by two holes
      with a specific shape (see <xref linkend="logo_stencil"/>).
