ARC3 @id,start,through,end,layer
| Argument | Meaning |

| through | A point it passes through, between the two. |
| end | The point it ends at. |

Notes
The centre, radius and direction are worked out from the three points whenever they move, so the arc always passes through all three. They must not be in a straight line.
