FreeCAD is a general purpose parametric 3D CAD modeler based on the OpenCASCADE geometry kernel. It's written in Python and its GUI utilizes Qt. It provides a modular plugin architecture and extensibility via macros and scripts, but already comes with a wide range of 2D and 3D property editing tools and transformation filters, simulation and rendering backends. Various export formats include STEP, IGES, OBJ, STL, DXF, SVG, STL, DAE, IFC or OFF, NASTRAN, VRML, DWG, and the native FCSTD files.

minor feature:
By switching to PySide (in place of PyQt) FreeCAD is now fully LGPL-compatible. The reusable parts library and parametric BOLTS models are now included. WebGL exports, a coherent units scheme, and GUI styling were added. Sketcher, Drawing and Raytracer modules were enhanced. A spreadsheet tool was added. DWG and IFC import and export overhauled.
