Surface
=======
.. module:: ezdxf.entities
:noindex:
SURFACE entity (`DXF Reference`_) created by an ACIS geometry kernel provided by
the `Spatial Corp.`_
.. seealso::
`Ezdxf` has only very limited support for ACIS based entities, for more
information see the FAQ: :ref:`faq003`
======================== ==========================================
Subclass of :class:`ezdxf.entities.Body`
DXF type ``'SURFACE'``
Factory function :meth:`ezdxf.layouts.BaseLayout.add_surface`
Inherited DXF attributes :ref:`Common graphical DXF attributes`
Required DXF version DXF R2000 (``'AC1015'``)
======================== ==========================================
.. warning::
Do not instantiate entity classes by yourself - always use the provided factory functions!
.. class:: Surface
Same attributes and methods as parent class :class:`Body`.
.. attribute:: dxf.u_count
Number of U isolines.
.. attribute:: dxf.v_count
