In this FreeCAD tutorial, I will show you how to use the Subtractive Pipe operation (often called a Sweep Cut in other CAD software) to remove material along a specific trajectory. We will start by creating a base solid and a path using a Polyline with fillets. You will learn how to align your sketches using Reference Geometry and perform a basic sweep cut. Then, we will take it a step further by using the Multisection mode to morph the cut from one shape (a Circle) to another (a Slot) as it moves along the path. This is a powerful technique for creating complex organic internal geometry in the Part Design workbench.
