PartDesign tutorial/en

Introduction
This tutorial is meant to introduce the reader to the basic workflow of the PartDesign Workbench.

This tutorial will continue working with the sketch that was created previously.



Requirements

 * FreeCAD version 0.16 or above
 * The reader has read the Sketcher tutorial

Creating 3D geometry
The purpose of the PartDesign Workbench is to allow the user to create geometry in 3D space to fulfill a certain need. As such, it is equipped with tools to make use of sketches and convert them to 3D objects.

There are two basic features to achieve this: Pad and   Revolution. Alongside their subtractive counterparts ( Pocket and Groove) they make up most of the common actions used by this workbench.


 * 1) Switch to the PartDesign Workbench
 * 2) Select the sketch that was created in the Sketcher tutorial
 * 3) Select [[Image:PartDesign_Pad.png|32px]] Pad
 * 4) Set the distance to 5 mm
 * 5) Select Ok

Another way to create 3D geometry is with the  Revolution tool.




 * 1) Create a sketch based on the image above
 * 2) Select [[Image:PartDesign_Revolution.png|32px]] Revolution
 * 3) Set the angle to 360°

Subtracting Features
We'll begin by creating a sketch with the shape we want to subtract.


 * 1) Select the top face of the Pad
 * 2) Select [[Image:Sketcher_NewSketch.png‎‎|32px]] New sketch
 * 3) Select [[Image:Sketcher_External.png|32px]] External Geometry
 * 4) Approach the edge of the pad. An arc should be highlighted
 * 5) Select the arc. An arc of a different color should appear in the sketch
 * 6) Create a circle centered on the same point as the arc and set its radius to 5 mm

Afterwards, we'll proceed to apply a Pocket feature.


 * 1) Select the sketch
 * 2) Select [[Image:PartDesign_Pocket.png|32px]] Pocket
 * 3) Set the distance to Through all

Pattern Features
We are now finished with the basic workflow for the Sketcher Module.
