FreeCAD 0.13.0803 
برنامج FREECAD مجاني و 
مفتوح المصدر و هو 
برنامج مفيد  للمدرسين و الطلبة 
للهندسة الميكانيكية و 
الديناميكا و مناسب للعديد  من التخصصات الاخري مثل 
الهندسة المعمارية ...
يشبه البرامج  
CATIA, 
SolidWorks , 
Solid Edge,   و يقوم بنفس العمل و ليس  بديل عن 
الأتوكاد كما يعتقد بعض الاخوة و يجري مقارنات بين 
الأتوكاد  و 
الفري كاد .
يسمح البرنامج بأنشاء الاجزاء و التعامل  معها:
      FreeCAD is a general purpose Open Source 3D CAD/MCAD/CAx/CAE/PLM     modeler, aimed directly at mechanical engineering and product design but     also fits in a wider range of uses around engineering, such as     architecture or other engineering specialties. It is a feature-based     parametric modeler with a modular software architecture which makes it     easy to provide additional functionality without modifying the core     system.
 
 
FreeCAD     is based on OpenCasCade, a powerful geometry kernel, features an  Open    Inventor-compliant 3D scene representation model provided by the  Coin   3D  library, and a broad python API. The interface is built with  Qt.    FreeCAD runs exactly the same way on Windows, Mac OSX and Linux     platforms.
Key features
•A complete     OpenCasCade-based geometry kernel allowing complex 3D operations on     complex shape types, and supports natively concepts like brep, nurbs,     booleans operations or fillets
•A modular architecture that  allow    plugins (modules) to add functionality to the core application.  Those    extensions can be as complex as whole new applications or as  simple as    python scripts or self-recorded macros
•A full parametric model allowing any type of parameter-driven custom objects, that can even be fully programmed in python
•Complete     access from python built-in interpreter, macros or external scripts   to   almost any part of FreeCAD, being geometry creation and    transformation,  the 2D or 3D representation of that geometry    (scenegraph) or even the  FreeCAD interface
•Import/export to standard formats such as STEP, IGES, OBJ, DXF, SVG, U3D or STL
In development
•A     Sketcher with constraint-solver, allowing to sketch     geometry-constrained 2D shapes. The sketcher currently allows you to     build several types of constrained geomerty, and use them as a base to     build other objects throughout FreeCAD.
•A Drawing sheets module     that permit to put 2D views of your 3D models on a sheet. This  modules    then produces ready-to-export SVG or PDF sheets. The module  is still    sparse but already features a powerful python functionality.
•A     Robot simulation module that allows to study robot movements. The   robot   module already has an extended graphical interface allowing   GUI-only   workflow.
•A Rendering module that can export 3D   objects for   rendering with external renderers. Currently only supports   povray, but   is expected to be extended to other renderers in the   future.
•An   Architecture module that allows BIM-like workflow,   with IFC   compatibility. The making of the Arch module is heavily   discussed by the   community here.
