If swept_object is a point list and there is no closure tag,
then sweep
connects n+1 successive copies of each
point (including the original) with straight line segments to form a
polyline. If there are m points in the original point list,
then m polylines with n segments each are formed by the
sweep. In this manner, sweep
forms a set of one-dimensional
objects (polylines) from zero-dimensional ones (points).
When there is a closure tag,
sweep
connects n
successive copies of each point (including the original) with straight
line segments and finally connects the last copy back to the original
to form a polygon with n sides. If there are m points in
the original point list, then m polygons with n sides
each are formed by the sweep. In this manner, sweep
forms a
set of two-dimensional objects (polygons) from zero-dimensional ones
(points).
Options
of the sweep
are copied directly to the resulting
polyline(s).
