I checked this and it seems to me that it always starts from the starting point of the element no matter where you click.
If you draw two Arcs, one constructed clockwise, the other constructed counter-clockwise you will see that the Magic Wand gives different result for them when creating linear segments based on them since the linear segments always start from the starting point of the Arc.
This means that we should have two things:
1. We should be able to see on every element the direction of their segments (clockwise or counter-clockwise) just like in case of Reference Lines of Walls and Beams.
2. We should have commands to invert this direction in case it is needed (just like in case of Wall Reference Lines).
