      FreeCAD is an open-source parametric 3D modeler made primarily to design
      real-life objects of any size. Parametric modeling allows you to easily
      modify your design by going back into your model history and changing its
      parameters.

      FreeCAD allows you to sketch geometry constrained 2D shapes and use them
      as a base to build other objects. It contains many components to adjust
      dimensions or extract design details from 3D models to create high quality
      production ready drawings.

      FreeCAD is designed to fit a wide range of uses including product design,
      mechanical engineering and architecture. Whether you are a hobbyist, a
      programmer, an experienced CAD user, a student or a teacher, you will feel
      right at home with FreeCAD.
