### Introduction

This tutorial is meant to introduce the reader to the basic workflow of the PartDesign Workbench. The reader will see how to create 3D objects based on Sketches, perform subtraction operations and how to replicate specific features in a pattern.

### Procedure

#### Creating 3D geometry

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

To achieve this, two tools are exist: 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. With the sketch selected in the tree view, press , choose the default XY-plane, and press OK. The sketch should appear now inside the Body.
4. Set the distance to 5 mm
5. Select Ok

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

1. Create a new body , and then a sketch based on the image above.
2. The sketch can be on any plane, but should be co-incident with the horizontal axis.
3. Select Revolution
4. Set the "Axis" to the "Horizontal Sketch Axis"
5. 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 flat face of the "Revolution"
2. Select New sketch
3. Select 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 hexagon centered on the same point as the arc and set the radius of the reference circle to 5 mm
External Geometry

When a 3D element has been created it is possible to create references to it within a sketch.

1. Select External Geometry.
2. Approach the element that you wish to reference, the edge of a Pad for example.
3. Click on it
4. New elements of a different color should appear on the sketch in the location of the feature you wish to reference.

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

1. Select the sketch
2. Select Pocket
3. Set the distance to Through all

#### Pattern Features

Recall the extruded profile that was created at the start of the tutorial.

1. Select the top face of the object
2. Create a new Sketch
3. Create reference geometry linked to the top arm of the figure
4. Create a circle constrained to the center of the reference arc
5. Set its radius to 3 mm
6. Pocket the sketch through all the workpiece

Instead of creating a circle for each hole in the sketch, we will introduce the concept of Pattern Features. These tools operate by replicating a feature in the workpiece that has already been created and that we wish to reproduce in a linear or circular arrangement. We will use a combination of Linear and Polar pattern features simulatneously to obtain the final workpiece.

1. Select the Pocket feature that we just created in the Tree View
2. Select MultiTransform

In the Combo View we are now asked to introduce the Transformations that we desire. Notice that in the MultiTransform parameters menu we see that FreeCAD has identified the Pocket as the Original feature and a second box requests us to Right click it to introduce the pattern features.

1. Right click the box
