Tutorial for Creating DXF Drawings
==================================
Create a new DXF document by the :func:`ezdxf.new` function:
.. code-block:: Python
import ezdxf
# create a new DXF R2010 document
doc = ezdxf.new("R2010")
# add new entities to the modelspace
msp = doc.modelspace()
# add a LINE entity
msp.add_line((0, 0), (10, 0))
# save the DXF document
doc.saveas("line.dxf")
New entities are always added to layouts, a layout can be the modelspace, a
paperspace layout or a block layout.
.. seealso::
:ref:`thematic_factory_method_index`
Predefined Resources
--------------------
`Ezdxf` creates new DXF documents with as little content as possible, this means
only the resources that are absolutely necessary are created.
The :func:`ezdxf.new` function can create some standard resources, such as
linetypes and text styles, by setting the argument `setup` to ``True``.
.. code-block:: Python
import ezdxf
doc = ezdxf.new("R2010", setup=True)
msp = doc.modelspace()
msp.add_line((0, 0), (10, 0), dxfattribs={"linetype": "DASHED"})
The defined standard linetypes are shown in the basic concept section for
:ref:`linetypes` and the available text styles are shown in the :ref:`tut_text`.
.. important::
To see the defined text styles in a DXF viewer or CAD application, the
applications have to know where the referenced TTF fonts can be found.
This configuration is not possible by `ezdxf` and has to be done for each
application as described in their documentation.

Simple DXF R12 drawings
-----------------------
The :ref:`r12writer` add-on creates simple DXF R12 drawings with a restricted
set of DXF types: LINE, CIRCLE, ARC, TEXT, POINT, SOLID, 3DFACE and POLYLINE.
The advantage of the :ref:`r12writer` is the speed and the small memory
footprint, all entities are written directly to a file or stream without
creating a document structure in memory.
