Anyone got the code to insert a basic spline with 2 points into a scene

Started to look up spline in the docs and its a tad daunting

Hi Niklas

Many thanks - a great helper

This is the sort of example we need in the documentation

Here's an example using the spline class:

import c4d  
from c4d import gui  
  
def main() :  
  myspline = c4d.SplineObject(2,c4d.SPLINETYPE_BEZIER)  #Create a 2pt. Bezier spline in memory only  
  p1 = myspline.GetSplinePoint(0)  #Assign the first point to a variable                  
  p2 = myspline.GetSplinePoint(1)  #Assign the second point to a variable   
  
  myspline.SetPoint(0, c4d.Vector(-100,0,0)) #Place the first point here  
  myspline.SetPoint(1, c4d.Vector(100,0,0))  #Place the second point here  
  myspline.Message(c4d.MSG_UPDATE)  #Should do this any time an object's points are changed     
   
  doc.InsertObject(myspline)  #Insert it into the Object Manager from memory  
  c4d.EventAdd() #Update C4D about the changes  
  
if __name__=='__main__':  
  main()

From here.
You can use the SplineData, SplineHelper, SplineLengthData classes on it to manipulate the points, segments, tangents.

Yeah. But he was asking how to make a two point spline based on the documentation.
And you posted an example using a spline object with it's points in the same positions as two objects.

He won't learn how to use the docs from that.
So I just thought that I'd give him an example that is based closer to how it's done in the docs.
That way he can see how they work. And be able to use the other functions and classes.
