API Reference > geometry-core > Curve > IntegratedSpiral3d > createRadiusRadiusBearingBearing createRadiusRadiusBearingBearing MethodStatic Create a transition spiral with radius and bearing conditions. createRadiusRadiusBearingBearing(radius01: Segment1d, bearing01: AngleSweep, activeFractionInterval: Segment1d, localToWorld: Transform, typeName?: string): undefined | IntegratedSpiral3d Parameter Type Description radius01 Segment1d radius (inverse curvature) at start and end. (radius of zero means straight line) bearing01 AngleSweep bearing angles at start and end. bearings are measured from the x axis, positive clockwise towards y axis activeFractionInterval Segment1d fractional limits of the active portion of the spiral. localToWorld Transform placement frame. Fractional coordinate 0 is at the origin. typeName string Returns - undefined | IntegratedSpiral3d Defined in curve/spiral/IntegratedSpiral3d.ts Line 185 Last Updated: 11 June, 2024
