Property: * Extended property status bitset. Mirror most of PropertyType and allow dynamic change property type. * Cache property name and type to improve performance * Centralize property status change signalling * Change aboutToSetValue()/hasSetValue() to virtual * Add new API getFullName() to obtain full quanlified name of the property AtomicPropertyChangeInterface: * Allow calling aboutToSetValue()/hasSetValue() when actually changed PropertyLists: * Refactor implementation by an abstract class PropertyListBase and a template class PropertyListsT, to allow better code reuse. PropertyListT is derived from AtomicPropertyChangeInterface to allow more efficient change on individual elements. * All list type property now accept setting python value as a dictionary with index as key to set individual element of a list. * Add touch list for more efficient handling of value changes. The list contains the index of changed value. And empty touch list should be treated as the entire list is changed. PropertyContainerPy expose this functionality with getPropertyTouchList(). PropertyPersistentObject: * New property to allow dynamic creation of any FreeCAD object derived from Base::Persistence, and use it as a property. DynamicProperty: * Use boost multi_index_container for efficient property lookup while keeping order. * Modify to be allowed to use in PropertyContainer directly PropertyContainer: * Use boost multi_index_container for efficient property lookup while keeping order. * Allow adding/removing dynamic property on all property container * Modify Save/Restore() to persist property status, and better handle transient property which can now be dynamically enabled/disabled per object. * Add new API getFullName() to obtain full quanlified name of the property. Implemented by Document, DocumentObject, and also ViewProviderDocumentObject if future patch DocumentObject and FeaturePython are modified to accommondate the dynamic property changes. Removed get/setCustomAttribute() implementation from DocumentObjectPy, and rely on PropertyContainerPy for the implementation, because of the additional dynamic property support in property container. Gui::ViewProviderDocumentObject, which is derived from PropertyContainer, is also modified accordingly

Overview
-
Freedom to build what you want 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.
-
Create 3D from 2D & back 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.
-
Designed for your needs 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.
-
Cross platform FreeCAD runs on Windows, Mac and Linux
-
Underlying technology
- OpenCASCADE A powerful geometry kernel, the most important component of FreeCAD
- Coin3D library Open Inventor-compliant 3D scene representation model
- Python FreeCAD offers a broad Python API
- Qt Graphical User Interface built with Qt
Installing
Precompiled (installable) packages are available for Windows and Mac on the Releases page.
On most Linux distributions, FreeCAD is directly installable from the software center application.
Other options are described at the wiki Download page.

Compiling
Compiling FreeCAD requires installation of several libraries and their development files such as OpenCASCADe, Coin and Qt, listed in the pages below. Once this is done, FreeCAD can be simply compiled with cMake. On Windows, these libraries are bundled and offered by the FreeCAD team in a convenient package. On Linux, they are usually found in your distribution's repositories, and on Mac OSX and other platforms you will usually need to compile them yourself.
The pages below contain up-to-date build instructions:
Usage & Getting help
The FreeCAD wiki contains documentation on general FreeCAD usage, Python scripting, and development. These pages might help you get started:
The FreeCAD forum is also a great place to find help and solve specific problems you might encounter when learning to use FreeCAD.
