API Reference > geometry-core > CartesianGeometry > Vector3d > angleTo angleTo Method Return the (Strongly typed) angle from this vector to vectorB. The returned angle is always positive and no larger than 180 degrees (PI radians) The returned angle is "in the plane containing the two vectors" Use planarAngleTo, signedAngleTo, angleToXY to take have angle measured in specific plane. angleTo(vectorB: Vector3d): Angle Parameter Type Description vectorB Vector3d target vector of rotation. Returns - Angle Defined in geometry3d/Point3dVector3d.ts Line 1196 Last Updated: 12 June, 2024
