API Reference > geometry-core > CartesianGeometry > Vector3d > planarAngleTo planarAngleTo Method Return the (as strongly typed Angle) Angle from this vector to vectorB. The returned angle can range from negative PI to positive PI (not closed on negative side) Use signedRadiansTo` to take have angle measured in other planes. planarAngleTo(vector: Vector3d, planeNormal: Vector3d): Angle Parameter Type Description vector Vector3d planeNormal Vector3d Returns - Angle Defined in core/geometry/src/geometry3d/Point3dVector3d.ts Line 1177 Last Updated: 13 June, 2024
