ODA File Converter Support
==========================
Use an installed `ODA File Converter`_ for converting between different versions
of `.dwg`, `.dxb` and `.dxf`.
.. warning::
Execution of an external application is a big security issue! Especially
when the path to the executable can be altered.
To avoid this problem delete the ``ezdxf.addons.odafc.py`` module.
The `ODA File Converter`_ has to be installed by the user, the application is
available for Windows XP, Windows 7 or later, Mac OS X, and Linux in 32/64-bit
RPM and DEB format.
At least at Windows the GUI of the ODA File Converter pops up on every call.
ODA File Converter version strings, you can use any of this strings to specify
a version, ``'R..'`` and ``'AC....'`` strings will be automatically mapped to
``'ACAD....'`` strings:
=========== =============== ===========
ODAFC ezdxf Version
=========== =============== ===========
ACAD9 not supported AC1004
ACAD10 not supported AC1006
ACAD12 R12 AC1009
ACAD13 R13 AC1012
ACAD14 R14 AC1014
ACAD2000 R2000 AC1015
ACAD2004 R2004 AC1018
ACAD2007 R2007 AC1021
ACAD2010 R2010 AC1024
ACAD2013 R2013 AC1027
ACAD2018 R2018 AC1032
=========== =============== ===========
On Windows the path to the ``ODAFileConverter.exe`` executable is
stored in the config file (see :mod:`ezdxf.options`) in the "odafc-addon"
section as key "win_exec_path", the default entry is:
.. code-block:: INI
[odafc-addon]
win_exec_path = "C:\Program Files\ODA\ODAFileConverter\ODAFileConverter.exe"
On Linux and macOS the ``ODAFileConverter`` command is located by the
:func:`shutil.which` function.
Usage:
.. code-block:: Python
from ezdxf.addons import odafc
# Load a DWG file
doc = odafc.readfile('my.dwg')
# Use loaded document like any other ezdxf document
print(f'Document loaded as DXF version: {doc.dxfversion}.')
msp = doc.modelspace()
...
# Export document as DWG file for AutoCAD R2018
odafc.export_dwg(doc, 'my_R2018.dwg', version='R2018')
.. attribute:: win_exec_path
Path to installed `ODA File Converter` executable on Windows systems,
