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.
