    Introduction A FreeCAD manual Note: The manual has been moved to the official FreeCAD wiki which is now its new home. If you wish to propose edits, please do them there, as this repository will be kept only for generating the ebook versions and will not be directly edited anymore. Introduction FreeCAD is a free, open-source parametric 3D modeling application. It is made primarily to model real-world objects, ranging from the small electronic components up to buildings and civil engineering projects, with a strong focus on 3D-printable objects. FreeCAD is free to download, use, distribute and modify, and its source code is open and published under the very permissive LGPL license. The data you produce with FreeCAD is fully yours, and can be recovered without FreeCAD. FreeCAD is also fundamentally a social project, as it is developed and maintained by a community of developers and users united by their passion for FreeCAD. This manual is an experiment at taking the opposite way from the official FreeCAD documentation wiki. The wiki is written collaboratively by dozens of community members and, like most wikis, it contains huge amounts of information, but is very hard to access and navigate by newcomers. This makes it a precious resource for reference, but not a very practical tool to learn FreeCAD. This manual will walk you through the same information available on the wiki. However, we hope that the more step-by-step pace, based on examples, and the more unified tone given by a smaller number of authors, will make it more suitable for a first contact with FreeCAD, and that it will become a perfect companion for the wiki. This manual has been written for the current stable version of FreeCAD which is version 0.16. All the contents of this manual are published under the Creative Commons 4.0 license, and can be freely used, downloaded, copied, and modified. The source files of this manual are hosted on github. This book has been written mostly by Yorik, but using a lot of information built by FreeCAD users, mostly from the FreeCAD wiki. The real author of this book is actually the whole FreeCAD community! 4

    What is FreeCAD? What is FreeCAD? FreeCAD is an open-source parametric 3D modeling application, made primarily to design real-life objects. Parametric modeling describes a certain type of modeling, where the shape of the 3D objects you design are controlled by parameters. For example, the shape of a brick might be controlled by three parameters: height, width and length. In FreeCAD, as in other parametric modelers, these parameters are part of the object, and stay modifiable at any time, after the object has been created. Some objects can have other objects as parameters, for example you could have an object that takes our brick as input, and creates a column from it. You could think of a parametric object as a small program that creates geometry from parameters. FreeCAD is not designed for a particular kind of work, or to make a certain kind of objects. Instead, it allows a wide range of uses, and permits users to produce models of all sizes and purposes, from small electronic components to 3D-printable pieces and all the way up to buildings. Each of these tasks have different dedicated sets of tools and workflows available. FreeCAD is also multiplatform (it runs exactly the same way on Windows, Mac OS and Linux platforms), and it is open-source. Being open-source, FreeCAD benefits from the contributions and efforts of a large community of programmers, enthusiasts and users worldwide. FreeCAD is essentially an application built by the people who use it, instead of being made by a company trying to sell you a product. And of course, it also means that FreeCAD is free, not only to use, but also to distribute, copy, modify, or even sell. 7
    What is FreeCAD? FreeCAD also benefits from the huge, accumulated experience of the open-source world. In its bowels, it includes several other open source components, as FreeCAD itself can be used as a component in other applications. It also possesses all kinds of features that have become a standard in the open-source world, such as supporting a wide range of file formats, being hugely scriptable, customizable and modifiable. All made possible through a dynamic and enthusiast community of users.
