Arrows
======

.. module:: ezdxf.render.arrows

This module provides support for the AutoCAD standard arrow heads used in
DIMENSION, LEADER and MULTILEADER entities. Library user don't have to use the
:attr:`ARROWS` objects directly, but should know the arrow names stored in it as
attributes. The arrow names should be accessed that way:

.. code-block:: python

    import ezdxf

    arrow = ezdxf.ARROWS.closed_filled


.. attribute:: ARROWS

    Single instance of :class:`_Arrows` to work with.


.. class:: _Arrows

    Management object for standard arrows.

    .. attribute:: __acad__

        Set of AutoCAD standard arrow names.

    .. attribute:: __ezdxf__

        Set of arrow names special to `ezdxf`.
