This add-on creates special DXF files for use by Gerber Technology applications which
have a low quality DXF parser and cannot parse/ignore BLOCKS which do not contain
data according the ASTM-D6673-10 standard. The function
DXF R12 and only DXF R12 files which do not contain the default “$MODEL_SPACE” and
“$PAPER_SPACE” layout block definitions, have an empty HEADER section and no TABLES
section. These special requirements of the Gerber Technology parser are annoying, but
correspond to the DXF R12 standard.
Autodesk applications maybe complain about invalid BLOCK names such as “Shape 0_M”, which in my opinion are valid, maybe spaces were not allowed in the original R12 version, but this is just a minor issue and is more a problem of the picky Autodesk DXF parser, which is otherwise very forgiving for DXF R12 files.

Exports the specified DXF R12 document, which should contain content conforming to the ASTM-D6673-10 standard, in a special way so that Gerber Technology applications can parse it by their low-quality DXF parser.
