= FreeCAD =

FreeCAD è un software Open Source di modellazione 3D di tipo CAD/MCAD/CAx/CAE/PLM, rivolto principalmente all'ingegneria meccanica e al design industriale. Si inserisce egregiamente in ambiti legati all'ingegneria civile e all'architettura, nonché in altri settori di interesse ingegneristico. La sua struttura modulare, volta principalmente alla modellazione solida, rende il software flessibile, facilmente modificabile e adattabile alle esigenze più variegate.

FreeCAD è basato sulla tecnologia OpenCasCade che mette a disposizione dei progettisti un ambiente di modellazione geometrica modulare e flessibile. Le scene 3D vengono renderizzate attraverso le librerie Coin 3D ed è possibile interagire con l'ambiente di progettazione attraverso lo scripting in python. L'interfaccia utente è invece basata sulle librerie Qt.

FreeCAD è multi-piattaforma, è pertanto possibile utilizzarlo in ambiente Microsoft®, OSx© e Linux.

Funzioni principali

 * [[Image:Feature1.jpg|left]] Il kernel basato su OpenCasCade permette operazioni complesse su profili di varia natura, anche molto articolati. È presente il supporto nativo al BREP, al NURBS ed alle operazioni di tipo booleano.


 * [[Image:Feature6.jpg|left]] La già citata architettura modulare permette l'estensione delle funzioni del programma attraverso l'utilizzo dei plugins. È inoltre possibile interagire con il software attraverso l'uso di macro.


 * [[Image:Feature3.jpg|left]] A full parametric model allowing any type of parameter-driven custom objects, that can even be fully programmed in python


 * [[Image:Feature4.jpg|left]] 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


 * [[Image:Feature5.jpg|left]] Import/export to standard formats such as STEP, IGES, OBJ, DXF, SVG, U3D or STL

In development

 * [[Image:Feature7.jpg|left]] 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.


 * [[Image:Feature8.jpg|left]] 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.


 * [[Image:Feature9.jpg|left]] A Robot simulation module that allows to study robot movements. The robot module already has an extended graphical interface allowing GUI-only workflow.


 * [[Image:Feature-raytracing.jpg|left]] 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.


 * [[Image:Feature-arch.jpg|left]] An Architecture module that allows BIM-like workflow, with IFC compatibility. The making of the Arch module is heavily discussed by the community here.

Manual
The FreeCAD manual is a work-in-progress community effort to provide state-of-the-art documentation about using FreeCAD, and is already available in a couple of languages. It still lacks much information, so feel free to join and contribute!

About the development
Check the Development roadmap for news about what is being planned, the Changelog and Roadmap mantis pages to see the progresses towards next release, or the Project statistics for even more information about the FreeCAD codebase.

Source code
FreeCAD can be compiled using cMake or autotools, the subversion link is https://free-cad.svn.sourceforge.net/svnroot/free-cad/trunk and there are build instructions for Windows, Unix/Linux and MacOSX.

Help wanted
FreeCAD would benefit greatly from your help, for example by testing and reporting bugs, or helping with extending and bettering the documentation destinated to newcomers, for example by writing or recording tutorials. Another problem we have, is lack of people to build and test FreeCAD on Mac OSX. If you have a mac, please help us! You are also welcome to help translating FreeCAD in your language.
