Type Alias: Arc ​

Arc = object

Defined in: geometry/arc.ts:9

Circular arc of an evaluated contour, the fillet of one corner (ADR-0001, DERIV-fillet-arc).

filletArc returns a degenerate arc (start = end) for a corner without fillet; such arcs never appear in a rounded contour.

Properties ​

center ​

readonly center: Point

Defined in: geometry/arc.ts:17

Center of the circle, kept for hit-testing and snapping.

end ​

readonly end: Point

Defined in: geometry/arc.ts:15

Tangent point on the outgoing edge, where the arc ends.

kind ​

readonly kind: "arc"

Defined in: geometry/arc.ts:11

Discriminant of a contour piece.

positive ​

readonly positive: boolean

Defined in: geometry/arc.ts:21

Whether the arc turns in the positive direction of angles: clockwise on screen (y down).

radius ​

readonly radius: number

Defined in: geometry/arc.ts:19

Radius, >= 0; an arc of a rounded contour always has a length (hasLength).

start ​

readonly start: Point

Defined in: geometry/arc.ts:13

Tangent point on the incoming edge, where the arc starts.
