FreeCAD will be a general purpose 3D CAD modeler. The development will be completely Open Source. As with many modern 3D CAD modelers it will have a 2D component in order to extract design detail from the 3D model to create 2D production drawings, although 2D (e.g. AutoCAD LT) is not the focus, neither are animation and organic shapes (e.g. Maya, 3D StudioMAX and Cinema 4D). I did not create the spec file. I only made a few modifications.
