1. Click the Bezier tool
2. Click and drag from where you want to place the first node. As you drag, two control points move in opposite directions from the node. The distance between the control points and the node determines the height or depth of the segment that you are drawing. The angle of the control points determines the slope of the segment.
3. Click and drag from where you want to place the next node. As you drag, two more control points appear. These control points let you change the segment further.
4. If you want to place another node, repeat step 3.
