There are three different shapes to choose from – circles, quadrilaterals, and triangles. In addition, it is possible to draw a free shape, or use shape recognition.
Select the shapes tool, and choose the type of shape required. The tool will then remember which shape was previously used, and will enable it by default.
Thickness, alpha, and colour can be customised.
Once a line type has been selected, the cursor will show as a crosshair. Click /press and drag to draw the shape.
