Ignore hatch style will hatch inward from the outer loop and ignores all internal loops.
Normal hatch style will hatch inward from the outer loop. If it encounters an internal intersection, it turns off hatching until it encounters another intersection. Thus, areas separated from the outside of the hatched area by an odd number of intersections are hatched, while areas separated by an even number of intersections are not.
Outer hatch style will hatch inward from the outer loop. It turns off hatching if it encounters an intersection and does not turn it back on. Because this process starts from both ends of each hatch line, only the outmost level of the structure is hatched, and the internal structure is left blank.
Defines the hatch style for determining which areas to hatch.
