In the documentation, the GetOffSetFromUnit and GetOffsetFromReal have their discription swapped. And I just can't get any usable value from the GetTangent function. If the spline is a flat spline, it always returns Vector(0,1,0).

Thank you for the error report in the docs. I fixed it.

About SplineHelp.GetTangent(), you should try to use SplineObject.GetTangent() :
import c4d from c4d import utils def MakeEditable(op) : if (not op) | op.CheckType(c4d.Ospline) : return op op = [op.GetClone()] doc = c4d.documents.BaseDocument() doc.InsertObject(op[0], None, None) op = c4d.utils.SendModelingCommand(command = c4d.MCOMMAND_MAKEEDITABLE, list = op, mode = c4d.MODELINGCOMMANDMODE_EDGESELECTION, doc = doc) return op[0] def main() : spline = MakeEditable(op) if (not spline) | (not spline.CheckType(c4d.Ospline)) : return for i in range(0, spline.GetTangentCount()) : tangent = spline.GetTangent(i) print tangent if __name__=='__main__': main()

I'd like to align my clone to the spline As I have the percentage along spline and the mograph clone matrix for each clone
using spltanvec = c4d.utils.SplineHelp.GetTangent( pospercent, smooth=True, realoffset=True) gives me an error - expecting spline help object?
out of the blue I added a spline help object used earlier in my code shelp = SplineHelp() shelp.InitSpline(spl,use_deformed_points=True)
spltanvec = c4d.utils.SplineHelp.GetTangent(shelp, pospercent, smooth=True, realoffset=True)
but this just gives me an unchanging vector - no matter what position percentage I use

I've posted the whole c4d file on CGSociety Maxon thread - coding. Any help appreciated.
