Rhino blend curve VS grasshopper blend curve

Hi all,

using blend curve in grasshopper, why I can’t choose different blend option for each curve as for rhino command?

setting, for example, Fa = 0.5 and Fb = 0 to simulate tangency and position, it generate unwanted cv at the end of the curve

Rhino command uses different CreateBlendCurve method.

Rhino:

Curve CreateBlendCurve(Curve curve0, System.Double t0, System.Boolean reverse0, BlendContinuity continuity0, Curve curve1, System.Double t1, System.Boolean reverse1, BlendContinuity continuity1)

Gh:

Curve CreateBlendCurve(Curve curveA, Curve curveB, BlendContinuity continuity, System.Double bulgeA, System.Double bulgeB)
