[QUOTE="Jhyrryl, post: 1041888, member: 6406"] Had to go to work and couldn't continue... :) Anyway, so a point at an intersection *must* belong in one or more of the squares bounded by the lines defining that point. In geometry, which we really don't have any choice but to use, the point actually belongs to *all* of the squares. When defining a bounded region, the points that define the line or curve of the boundary are included in the region. Equations that evaluate whether an intersection will occur between a given intersection and some other geometric "object" will always evaluate as "true", even if the only such intersection is a point that makes up the boundary -- in this case, a corner. Actually, I guess this isn't exactly correct, as it would result in a 5 ft. (or even a 10 ft.) corridor always generating cover. The rules for cover are a little more complicated. [/QUOTE]
