Thank you very much for addressing my question Tim. Your method described here makes a lot of sense if we realize that sketchup is treating the breadboard as a hollow "skin" instead of a solid board.

Tim, it seems like doing an intersect between the Breadboard and the top should give you the same result, but it doesn't seem to work when both the top and the breadboard end are defined as components. Any idea why?

It seems to work when the breadboard is not defined as a component.
