A wrapper for `ezdxf `_ providing methods for
converting :class:`cadquery.Workplane` objects to DXF entities.
The ezdxf document is available as the property ``document``, allowing most
features of ezdxf to be utilised directly.
.. rubric:: Example usage

:caption: Single layer DXF document

Export Workplane content to DXF. Works with 2D sections.
:param w: Workplane to be exported.
:param fname: Output filename.
:param approx: Approximation strategy. None means no approximation is applied.
"spline" results in all splines being approximated as cubic splines. "arc" results
in all curves being approximated as arcs and straight segments.
:param tolerance: Approximation tolerance.
:param doc_units: ezdxf document/modelspace :doc:`units ` (in. = ``1``, mm = ``4``).
