update for DXF-Importer v1.12, DXF-Exporter v1.29 - 2009.04.11 by migius
- added DWG support, adapted Stani Michiels idea for binding an extern
DXF-DWG-converter
The external DXF-DWG converter "dconvertcon.exe" 355kb comes from
openDesignAlliance www.opendwg.org, is free, but not opensource, not
GPL-compatible (can not be bundled with commercial programs), so must be
downloaded and installed in Blender script folder by user. It is a DOS console
application, can be started in background mode, works on Windows, and in Wine
on Linux and OSX. Version 1.0 (2002) supports conversion between DXF<->DWG for
autocad release: 2.5, 2.6, 9, 10, 11, 12, 13, 14, 2000, 2002.
