5. Create a series of arcs.
 * 5.1. Click on.
 * 5.2. Approach the endpoint of one of the construction lines, and click on it. This will set the center point of the circular arc to be Constraint_PointOnPoint.svg coincident with this line's endpoint.
 * 5.3. Click once in the 3D view at an arbitrary location to set simultaneously the radius of the arc, and the first endpoint of it. Define an approximate radius of.
 * 5.4. Move the pointer in an anti-clockwise direction to trace an arc that has its concavity pointing towards the origin of the sketch. Click to set the final endpoint of the arc, defining a circular arc that approximately sweeps or half a circle.
 * 5.5. Repeat these steps with each construction line, so that each of them has a circular arc at its tip. We will call these O-arcs for outwards-arcs.
