Hi.

I've wanted to work on the code that handles the various
DWG formats,
and several months ago I received some documentation about
newer DWG
formats. Sadly I've not made any progress in coding up
routines to
handle newer DWG formats. The existing DWG reading code
needs cleaning
up, and then I need to start working on new code for the new
formats.

I'd like to be able to support the AC1018 format, but I
don't have a
timeline as to when that will happen. My work over the last
couple of
months has been concentrated on improving the GUI
responsiveness, fixing
bugs, and adding an occasional new feature. I regret that
still the code
needed for directly importing older DWG/DXF files is not
written as
well as the lack of code for newer version of these files. 

Thanks for the kind words regarding PythonCAD.

We had a start on implementing DXF -> pythoncad
conversion in 
vectorsection.  The trouble with DWG is that it is as
convoluted as DXF 
but also in a very bit-juggly binary format (e.g. some
values take 2-3 
bits and various other not-8 widths.)  The first issue makes
it 
difficult because of the conceptual mapping of entities. 
The second is 
just really hard to code and debug.

It's difficult, but not impossible.  If anyone is
interested in working 
on it, I'm more than happy to help you get started.  The
first goal for 
vectorsection would be a standalone dxf<->pythoncad
conversion.  From 
there, we would handle dwg<->pythoncad (where the
conceptual mapping 
stuff would be done and we would basically only need a
working DWG 
class to drop-in as a replacement for the DXF stuff.)  After
that, 
pythoncad could use the standalone converters directly or
steal some 
code.
