Sometimes you would like
to be able to take a pair of scissors to a shape – make a wavy or straight cut
across it. You can do this with Breaklines. Using the ‘Break line’ button,
having already selected a closed-outline Line object, you enter the Break Mode.
Next, select an input mode to draw your line across the shape, and right-click
to end drawing. You can edit the line before it is used. Once you have the line
as you would like, use the “Cut the object” button to make the cut. You will now
have multiple objects.
