Angle between two Vector3d, Vector Direction of a Line3d

Hi !

I have given two Lines ( Rhino Geometry ) to be Input Parameters to PythonScript in Grasshopper. I have to determine the Angle between the two Lines by their Vector3d.

How does the Python Code has to be generated ?

Many regards

You can use the Rhino.Geometry.Vector3d.VectorAngle method:
