Summary
Regions are two-dimensional areas you create from closed shapes or loops.
Closed polylines, lines, and curves are valid selections. Curves include circular
arcs, circles, elliptical arcs, ellipses, and splines.
You can combine several regions into a single, complex region.
Closed 2D and exploded planar 3D polylines in the selection set are converted
to separate regions and then converts polylines, lines, and curves to form
closed planar loops (outer boundaries and holes of a region). If more than two
curves share an endpoint, the resulting region might be arbitrary.
