Translations:Creating a simple part with Part WB/3/en

This tutorial aims to be used as a first introduction to 3d modeling using the Part Workbench of FreeCAD. After having finished this tutorial you should be able to make simple 3d models by using primitives like cubes, cylinders, etc with a technique called Constructive Solid Geometry, short CSG modeling. Another way to create 3d models is by using a 2d shape to create a 3d shape by for example extruding or revolving the 2d shape in 3d space. For an introduction of that technique please follow the sister-tutorial Creating a simple part with PartDesign. The two tutorials intentionally have exactly the same model generated, this presents the beginner with a hands on experience of the two different techniques and how they are implemented in FreeCAD. The definition of the two techniques can be viewed as strictly divided from a semantic point of view, however there is nothing directly hindering a mix of the techniques when creating models. There are some caveats to watch out for when mixing modeling techniques, those are mainly related to aspects of how FreeCAD is programmed. There is a third tutorial intended as a first introduction to a mixed modeling example. That tutorial uses the Draft Workbench to create a 2d profile utilized to extrude a solid in the Part Workbench to make the same model as in this tutorial.
