The Polyline tool allows you to create shapes and outlines with an arbitrary number of sides on the document. The Polyline works exactly the same as the Polygon only it can have an open ending or side. Hold the Shift key while drawing to make horizontal, vertical, or 45 degree angle lines. Once placed shapes can be modified by dragging any of the resize handles on the vertices of the shape.
