You have probably misplaced the control points -- they determine how long
segments will be drawn. See the attached picture which displays their
correct position.

You may draw a segment either, but you get solid line crossing the
passage. Drawing a curve makes it possible to control the omitted part in
the middle. Even if you draw a curve, displayed will be straight segments,
not a curve.
