Write a DXF drawing
===================

Round-trip a real 2D drawing through PyVista back out to DXF. The
layer assignment of every cell is preserved on the ``cad.layer``
array.

This example loads a real multi-layer DXF from the ezdxf project
(MIT), with entities on layers ``0``, ``BLUE``, ``RED``, writes it back
to a new DXF, and renders the source and the round-tripped result
side by side so any loss of detail is immediately visible.
