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.
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.
Another way to create 3D geometry is with the Revolution tool.
We'll begin by creating a sketch with the shape we want to subtract.
Afterwards, we'll proceed to apply a Pocket feature.
Recall the extruded profile that was created at the start of the tutorial.
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.
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.
After completing this task you should have the following result.
If not, re-edit the MultiTransform operation by double clicking on it in the Tree View. Check both pattern features to detect necessary modifications, such as the Axis and if the Direction needs to be reversed.
We are now finished with the basic workflow for the PartDesign Workbench.
