FreeCAD 0.17 Description:
FreeCAD is an open source, full-featured and general purpose 3D modeler specifically designed to be used for CAD, MCAD, CAE, PLM and CAx work. It is a multi-platform software that supports mainstream operating systems. The application features a rock-solid OpenCasCade-based geometry kernel, full parametric model, an Open Inventor-compliant 3D scene representation model, a Python API, as well as some key concepts like workbenches, macro recording, and the ability to run as a server. Another interesting feature of this CAD software is its modular architecture, which will extend its default functionality through plugins or modules. It can export or import files to/from the VRML, SVG, STEP, OBJ, IGES, STL STL, DXF, DAE, NASTRAN, IFC or OFF.
