In this lesson you will learn how to draw cross-sections.  A cross-section shows the interior details of an object.  It shows how an object is put together, or how the different parts look once inside the object.  You will often find this in books such as David Macaulay's The Way Things Work.  

Below you will see two drawings. The top one is an isometric to show you where the sections you will be drawing are located. In is included here as a reference for you. The bottom one is the one you will actually be drawing. It shows three cross-sections.
