The starting half-width becomes the default ending half-width. The ending
half-width becomes the uniform half-width for all subsequent segments until
you change the half-width again. The starting and ending points of wide line
segments are at the center of the line.
Typically, the intersections of adjacent wide polyline segments are beveled.
No beveling is performed for nontangent arc segments or very acute angles
or when a dot-dash linetype is used.
