Polyline Tool

Polyline.pngUse the Polyline tool to draw shapes with 2 or more line segments.

Click to set each node on the Polyline and Doubleclick to set the last node and finish drawing that Polyline.

While you're drawing a Polyline, you can remove the last defined node by using the Backspace key on your keyboard.

You can add nodes to an existing Polyline by rightclicking on a segment and selecting Add Node.

You can delete nodes from an existing Polyline by rightclicking on a node and choosing Delete Node.

The default Fill for a Polyline is "Transparent", or "0,255,255,255" using the ARGB color model, and this creates an 'open' Polyline, i.e. the last and first nodes are not connected and there is no fill color.  To change a Polyline into a Polygon just choose a different Fill Color; this will add a line segment between the last and first nodes of the Polyline and apply your chosen Fill Color.
