Normal Vector to some awkward looking plane..

Area and Volume of awfully weird shape which you never knew why such shapes were created..

Finding the tolerance for some shaft to fit into some hole (don't let your mind wander here)..

How fast does a metal corrode in a bridge.. to ensure that by the time a person uses it after 1 year, he won't fall and die..

Draw a Layout Drawing for some jet engine used in some aircraft.. hopefully the foreman who redraws it understands your scribbling which you aptly call it Layout Drawing..

Ahhh.. studying is fun. It's then you really know what your lecturer have been teaching all this while.
