This is as good as OpenDWG which is also providing the libraries for reading DWG formats. Since the DWG is CAD format used by AutoDESK which is known to have changed their file formats over last 10+yrs (under the same file extension) this project needs lot of support for it has a moving goal. libdwg is "An open C library to directly read DWG files, a popular drawing format used in the CAD world." - It tries to read the DWG CAD format of AutoDESK and can be of help for any Free CAD software project.Inkscape is a native SVG editor which has as part of it's road map CAD tools inline with technical illustration and traditional 2D CAD activity.CADEMIA is simple CAD tool made in JAVA it can import DXF format.
FreeCAD is existing project on written in C and Python seems promising.Best part is Python seems to be right choice for free software. PythonCAD is simple 2D CAD software in Python recently this has been rewritten to improve speed.Some more cad software listings: linuxmafia.Various (ex-commercial or unknown stage) other cad packages brlcad, varkon or, GraphiteOne.But - the 3D displaying technology and rendering is there, blenders interface is very theme driven, maybe a starting point. Blender is about artists expressing there imagination. However CAD is mainly about 3D geometric driven design and then deriving 2D drawing from it. Blender - once had the idea to fork a cad version.It is in very early stages, aimes for cross plattform use, but i fear java the wrong choice for a demanding piece of software We also have pythonOCC is a set of open-source Python bindings for OpenCascade, distributed under the terms the CeCILL Licence It was started or at least is pushed by airbus - i think to avoid vendor lock-in with long running aeroplane design projects that go on for decades. the opencascade project provides a software stack that has many foundations for CAD/FEM/CFD Software.QCAD an easy to use 2d-CAD, available in a closed source professional and a GPLed community edition.Archimedes is free CAD software built over Eclipse’s Rich Client Platform fully based on plug ins.Please help us collecting existing Computer Automated Design and related software projects.
