In this Step the chest bottom, front and back are created.

Use the Line or Rectangle Tool to create an edge face for the Bottom. Double click on the rectangle, then right click, and choose Make Component from the menu.  Name the component Bottom.

Note that the following steps in making new components are executed in the context of the overall chest assembly. This is much more efficient and accurate than making components in isolation or free space, and then assembling later.
Edit the Bottom component, and use the Push/Pull Tool to give it a width across the full length of the groove in the Ends.

Use the Rectangle Tool to outline the face of the Front. Double click and right click, then pick Make Component from the menu.

Then, with the Push/Pull Tool, pull out a thickness of 5/16-in. The Front and Back components are 1/2-in. thick with a 3/16-in. deep rabbet around the edges for housing the End and Bottom components.  
To create the rabbet, orbit around for a rear view of the Chest (shown below). Edit the Front component and draw lines in the intersecting corners of the Bottom and Ends. Then with the Push/Pull Tool, pull out another 3/16-in. thickness to the inside face of the Front. This results in creating the 3/16-in. deep rabbets around the inside face of the Front.

You can verify the surrounding rabbets by making a copy of the Front, and moving it away from the assembly.

 
Make a copy of the Front component and move it to the rear of the assembly. Right click on the copy and choose Flip Along Component’s Green to orient into the back of the assembly.

Currently, a common component definition is being used for both the Front and Back. Eventually, there will be a need to have independent definitions for the Front and the Back. The front will require unique cuts for the front lock. And the back will have recesses for the hinges. Delaying the separation is efficient since there is much commonality in grooves and rabbets. See Figure 17 for status after six steps.

Here is the video showing these steps.
