We have a new tool, [icon]/images/ggb/toolbar/mode_polygon.png[/icon], which lets you draw new figures or outline figures you drew before. Use the line tools[icon]/images/ggb/toolbar/mode_join.png[/icon] to draw a shape with your choice of sides, use the point tool[icon]/images/ggb/toolbar/mode_point.png[/icon] to mark an intersections you need for your figure, then you can use [icon]/images/ggb/toolbar/mode_polygon.png[/icon] to outline the figure by clicking on the vertices of your figure; it will also fill in the figure you outline. Use [icon]/images/ggb/toolbar/mode_polygon.png[/icon] to free draw a figure also. Feel free to play around with these features until you are comfortable with them.
