Introduction
This is the documentation website of FreeCAD. It is written by the community of FreeCAD users and developers, and is continuously being updated and extended. It might therefore contain errors, inaccuracies, or articles that describe functionality that is not yet available on the version you have installed. We try our best to fix these and make this documentation better, don't hesitate to help and contribute!

Getting started
FreeCAD is an open-source general purpose parametric 3D CAD modeler, made for product design, that is, anything you plan to build in the real world. It is mainly made for two categories of users: Professional users from the fields of mechanical engineering and product design but also from a wider range of uses around engineering, such as architecture or other engineering specialties, and also hobbyist and casual users who need a tool to model objects they want to build or 3D print. It can also be used by developers who wish to build their own application using FreeCAD as a base.

Modeling for product design is usually a complex task, where precision is important. FreeCAD is therefore also a complex tool with a fair learning curve. This documentation will hopefully help to make this learning phase an interesting and enjoyable experience.

Workbenches
The FreeCAD interface is based on the concept of workbenches. Workbenches are sets of tools typically designed for a specific task. Switching between these workbenches changes several parts of the FreeCAD interface such as toolbars and menus, while still working on the same document. Most of the tasks you will do in FreeCAD will require a specific workbench to be activated. Click the  icons below to show the tools of each workbench.


 * The Part workbench provides basic tools for working with solid parts: primitives, such as cube and sphere, and simple geometric operations and boolean operations. The Part workbench provides the foundation of FreeCAD's geometry system, and is used by almost all other workbenches.

Customizing
The workbench system is not to be considered as a limitation to your freedom, but simply a way to organize large quantities of tools and offer different workflows inside a single application. They are however extensively customizable, so you can tailor your interface to your preferences and needs.

 * Modifying user preferences CLEANUP
 * Creating macros
 * Macros recipes

Scripting
Strong support to python scripting is one of the main strengths of FreeCAD. Almost any part of the FreeCAD application is accessible to python scripting: the core application, the interface, the 3D view, and almost all of the modules functionality. Python scripting can be used from the FreeCAD python console, from macros, from external scripts or even from external applications, FreeCAD being importable as a python module.
