Thank you both for providing some more insight into this. The sample I had provided was to merely show on a very basic level the idea I was trying to find an answer to. My model is actually very different than this but Alan I appreciate you spending the time to show the process you would follow to build out a box. I guess I was approaching the model similar to actually building the box in real life. Each side piece front and back piece are their own components as well as the bottom and the top. What I wanted to do from there was cut the box as I would with a band saw to ensure a good seam between the bottom (container) and the top (lid), not thinking at the time that it would be difficult to achieve in SketchUp. I will likely back pedal to my components and adjust at that point to construct the full lid as opposed to the piece of wood placed across the top.
