Firstly position the duplicate path to form a love heart either by dragging it or pressing the right hand arrow key. Then you can drag the start and end points drag the control points to change the curvature Bezier paths and drag the adjustment handles to fine tune the shape and smoothness of the control points. If false fewer calculations are performed but calculating positions along the path is less accurate. Because the segments are connected end to end the last and first control points of successive curves are the same and we can omit one of the duplicates. Although they are all used mathematically in the same manner the first and last points end up also being the start and end of the curve and the other two points are never reached by the curve.
