# class ImmutableArc

---

Arc element defined by a start point, end point, center point, and orientation. Note that an arc cannot be fully defined without the orientation specified. Arcs with equal start and end points are considered a full circle, except for the case where radius equals 0 in which case the arc is undefined.

ImmutableArc inherits from Shape

# CONSTRUCTORS

# constructor ImmutableArc()

Description: Create an arc of length 0 at 0,0.

# constructor ImmutableArc(center, start, end, direction)

Description: Create an arc from three points, start, end, and center. Direction is always required otherwise it is unknown which of the two possible arcs to create for the given points.

Parameters:

• center: (ImmutablePoint) - Arc center
• start: (ImmutablePoint) - Starting point
• end: (ImmutablePoint) - Ending point
• direction: (Direction) - Direction of the arc.
