Draw Polyline Arcs
A polyline is a connected sequence of line segments created as a single object.
You can create straight line segments, arc segments, or a combination of the
two.
Multisegmented lines provide editing capabilities unavailable for single
lines. For example, you can adjust their width and curvature. After you've
created a polyline, you can edit it with
PEDIT or use EXPLODE to convert it to
individual line and arc segments. You can
■ Convert a spline-fit polyline into a true spline with SPLINE
■ Use closed polylines to create a polygon
■ Create a polyline from the boundaries of overlapping objects
