Constructs a pieccewise linear approximation to a clothoid spiral. Curvature is the reciprocal of the radius, so specify a curvature of 0 for an infinite radius. curveLength is the design length of the curve.
[Visual Basic .NET] Public Function ConstructClothoidByLength ( _ ByVal pFrom As IPoint, _ ByVal pFromTangent As IPoint, _ ByVal bCurveRight As Boolean, _ ByVal fromCurvature As Double, _ ByVal toCurvature As Double, _ ByVal curveLength As Double, _ ByVal __MIDL__IConstructClothoid0000 As esriCurveDensifyMethod, _ ByVal densifyParameter As Double _ ) As IPolyline
