createLineSpiralSpiralLine MethodStatic

Compute 2 spirals (all in XY) for a symmetric line-to-line transition.

  • First spiral begins at given start point.
  • first tangent aims at shoulder
  • outbound spiral joins line from shoulder to target.

createLineSpiralSpiralLine(spiralType: IntegratedSpiralTypeName, startPoint: Point3d, shoulderPoint: Point3d, targetPoint: Point3d): undefined | GeometryQuery[]

@returns array with the computed spirals, or undefined if failure.
