FreeCAD is made for everybody, by everybody. The new parameter object is easy to code. Properties of one object can drive property values of other objects, allowing for complex chains of custom parameters that can only exist in your wildest dreams. All shape changes are recalculated as needed, recorded by the undo/redo stack, and allow accurate modeling history to be maintained. All FreeCAD objects are themselves parametric, which means their shape can be based on properties such as values, text, on/off buttons or even other objects. It supports solids, Boundary Representation (BRep) objects, and Non-Uniform Rational Basis Spline (NURBS) curves and surfaces, and provides a wide range of tools to create and modify these objects, including complex Boolean operations, fillets, shape cleanup, and more of.

FreeCAD has an advanced geometry engine based on Open CASCADE technology. FreeCAD provides tools to generate, export and edit solid, full-precision models, export them for 3D printing or CNC machining, create 2D drawings and views of models, perform analyses such as finite element analysis, or export model data such as quantities or materials list. Everything you do in FreeCAD uses real-world units, whether it's microns, kilometers, inches, or feet, or even any combination of units. FreeCAD is primarily used to design objects for the real world. FreeCAD is 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. The development is completely Open Source (LGPL License). FreeCAD is a general purpose parametric 3D CAD modeler.
