The technique shown in this 3ds Max tutorial is meant to be a design modeling technique. Watch and learn how to model the Beijing Olympic Stadium in 3D Studio Max.
A form that resembles the stadium was modeled then sliced randomly to get edges in an editable poly. Those edges are then chamfered and extracted to then be shelled. In this video the slice plane is used within the element sub-object level. Thinking about it a bit more the quick slice option might have been more suitable for the exercise.
Disclaimer: Just to be clear David Feno isn't trying to reduce the complexity and elegance of the stadium which has far more thought than just random slices /patterning in a form. What he is putting forward is a technique with which one could quickly go about modeling a similar pattern in 3ds Max.
