21.17 POLYLINE (PLINE)
Polyline is basically a composite curve which is a combination of linear and arc segments in
AutoCAD. The other property that can be varied is the thickness of the line drawn. Special
properties of the polyline are:
(a) All the connected segments are treated as single entity.
(b) Width of line of any or all segments can be varied.
(c) It can also be a closed curve.
(d) Line type can be varied as required along various segments of the line.
