Library and command line tools to handle DWG files

GNU LibreDWG is a C library to handle DWG files. It aims to be a free replacement for the OpenDWG libraries. DWG is the native file format of AutoCAD. LibreDWG was based on LibDWG (http://libdwg.sourceforge.net), which is written with variable names, documentation, and comments in Esperanto. There are also command line tools and libraries to read and write DWG files, with converters for various formats (DXF, DXFB, SVG, PS, JSON, XML, etc.) and a SaveAs functionality, to convert between the various DWG versions. It can read r13-r2018 DWG, write r13-r2000 DWG, write r11-r2018 DXF ASCII and binary. Much more object types than any other free DWG library.
