Spiral tool for grasshopper

I have done this one Spirale.gha (21 KB) It has these paramters “AxisStart”, “AS”, “Point of start”, “AxisDirection”, “AD”, “Direction” “HelixStart”, “HS”, “Point of start of helix” “Pitch”, “P”, “Pitch”, “TurnCount”, “TC”, “TurnCount”, “R1”, “R1”, “Radius of begining”, “R2”, “R2”, “Radius of end”, And use this method from Rhinocommon Rhino.Geometry.NurbsCurve.CreateSpiral(axisStart, axisDir, radiusPoint, pitch, turnCount, r1, r2)) https://developer.rhino3d.com/api/RhinoCommon/html/M…
