What is a "hole"

I would like a little clarification of what Cura calculates to be a hole.  So far, I have found that when looking down on the model in Cura, a hole can be any shape.  Round, oval, square, or even just plain weird.  And everything I have seen so far has no bottom and no top. 

I would guess, however, that since Cura slices layer by layer, a hole would be any space that is enclosed on all sides in the layer being sliced.  If that is the case, how would a horizontal hole on the side of a model, like a screw hole, get expanded since it would be open on one side?

    You are right.  A horizontal hole will not be expanded because it isn't vertical.  Note that the Horizontal Expansions settings are with the rest of the Wall settings.  Those settings only affect the XY.

    So your horizontal hole must be designed correctly.  Thick layer heights can make the hole oval shaped with the long axis in the Z.  Cura has to hit the next layer height and it rarely is exactly at the quadrant of the circle.  The tops and bottoms of horizontal holes are characteristically flat.

    When it's necessary I chase them out with the appropriate drill.  Pin chucks come in handy.
