If the top view of an object shows a drilled-through hole, how many hidden lines will be necessary in the front view to describe the hole? How many if the hole is countersunk? Counterbored?

A hole in the front view requires two hidden lines.
A countersunk hole in the front view requires five hidden lines.
A counterbored hole in the front view would also require five hidden lines.
