API Reference > geometry-core > Curve > CylindricalRangeQuery > buildRotationalNormalsInLineStrings buildRotationalNormalsInLineStrings MethodStatic Recurse through geometry.children to find linestrings. In each linestring, compute the surface normal annotation from the curve tangent stored in the linestring the axis of rotation a default V vector to be used when the linestring point is close to the axis. buildRotationalNormalsInLineStrings(geometry: AnyCurve, axis: Ray3d, defaultVectorFromAxis: Vector3d): void Parameter Type Description geometry AnyCurve axis Ray3d defaultVectorFromAxis Vector3d Returns - void Defined in core/geometry/src/curve/Query/CylindricalRange.ts Line 97 Last Updated: 13 June, 2024
