Optionalpoints: Point2[]Optionalclosed: booleanOptionalbulges: number[]Points defining the polyline vertices
OptionalclosedWhether the polyline is closed
OptionalbulgesBulge values for each vertex (optional) Bulge = tan(angle/4) where angle is the arc angle in radians Positive = counterclockwise, Negative = clockwise 0 = straight line segment Array length should match points length (or be undefined for all straight segments)
Polyline segment defined by multiple points Can include bulge values to create arc segments between vertices
