Write the files using an only style polyline. You don't need the handles
and all the other junk that Autodesk now requires in DXF files now for
some of the newer entity types. The following is all you would need for
a polyline.
This works because AutoCAD will support older file format versions of
DXF which didn't have nearly as much info. Once you start using newer
entities or items in the DXF file, AutoCAD then needs a lot more junk to
go with it to support them. Handles are just one of those things that's
needed in a newer DXF file version that isn't in the older ones.
