computeElbowDirection Function
Computes the direction vector for an "elbow" for leader based on the attachment point and a frame curve. The elbow direction is determined by whether the attachment point is closer to the left or right side of the frame. If the computed elbow would be tangent to the frame at the intersection, no elbow direction is returned.
computeElbowDirection(attachmentPoint: Point3d, frameCurve: Loop | Path, elbowLength: number): Vector3d | undefined
@returns The direction vector for the elbow, or undefined if the elbow would be tangent to the frame.
| Parameter | Type | Description |
|---|---|---|
| attachmentPoint | Point3d | The point where the leader attaches. |
| frameCurve | Loop | Path | The frame curve (either a Loop or Path) to which the leader is attached. |
| elbowLength | number | The length of the elbow segment to be created. |
Returns - Vector3d | undefined
The direction vector for the elbow, or undefined if the elbow would be tangent to the frame.
