.. _r12export_addon:
.. module:: ezdxf.addons.r12export
R12 Export
==========
.. versionadded:: 1.1
This module exports any DXF file as a simple DXF R12 file. Many complex entities will be
converted into DXF primitives. This exporter is intended for creating a simple file
format as an input format for other software such as laser cutters. In order to get a
file that can be edited well in a CAD application, the results of the ODA file converter
are much better.
Usage
-----
.. code-block:: Python
import ezdxf
from ezdxf.addons import r12export
doc = ezdxf.readfile("any.dxf")
r12export.saveas(doc, "r12.dxf")
Converted Entity Types
----------------------
=============== ===
LWPOLYLINE translated to POLYLINE
MESH translated to POLYLINE (PolyfaceMesh)
SPLINE flattened to POLYLINE
ELLIPSE flattened to POLYLINE
MTEXT exploded into DXF primitives
LEADER exploded into DXF primitives
MLEADER exploded into DXF primitives
MULTILEADER exploded into DXF primitives
MLINE exploded into DXF primitives
HATCH exploded into DXF primitives
MPOLYGON exploded into DXF primitives
ACAD_TABLE export of pre-rendered BLOCK content
=============== ===
For proxy- or unknown entities the available proxy graphic will be exported as DXF
primitives.
Limitations
-----------
- Explosion of MTEXT into DXF primitives is not perfect
- Pattern rendering for complex HATCH entities has issues
- Solid fill rendering for complex HATCH entities has issues
ODA File Converter
------------------
The advantage of the :mod:`~ezdxf.addons.r12export` module is that the ODA file converter
isn't needed, but the ODA file converter will produce a much better result:
.. code-block:: Python
from ezdxf.addons import odafc
odafc.convert("any.dxf", "r12.dxf", version="R12")
