Class :blue:`MbContourWithBreaks` is declared in file *cur_contour_with_breaks.h*.

A two-dimensional contour with breaks is a derived class of a two-dimensional contour
:ref:`MbContour <MbContour_Two-Dimensional_Contour_>`, Fig. 1:

   :width: 12cm

A two-dimensional contour with breaks is defined by a set of
**segments** of curves joined to each other, a periodicity flag
*closed*, breaks **breaks**, a set of visible parts of the contour
**visibleContours**, and a set of contour segment indices
*baseSegNumbers* that define fixed break points.

A contour with breaks is shown in Fig. 2:

Other two-dimensional contours must not be used as segments
of a two-dimensional contour with breaks.

A two-dimensional contour with breaks is used only for building
multilines.
