Regions are two-dimensional areas created from closed shapes or loops. Closed polylines, lines, and curves are valid selections. Curves include circular arcs, circles, elliptical arcs, ellipses, and splines.

Closed polylines in the selection set are converted to separate regions. As a consequence, polylines, lines, and curves are converted to form closed planar loops [outer boundaries and holes (islands) of a region].

It is possible to add islands inside a region as well.
