PartDesign tutorial

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 substractive 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 circe centered on the same point as the arc and set its radius to 5 mm radius

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.
