Evaluate Curvature

Hello

I need to evaluate the curvature of the following curve. I cannot get the Curvature component to work. (Error: Curvature is infinite at: ... a long list of points) I'm not sure what the Derivatives component outputs? ("point" and "first derivatives"). I would expect a slope of the tangent to the curve at a given point. Can anyone please help

Hey,

In your screenshot, you are trying to get the curvature in the polyline instead of an arc(degree 2) or other nurbs curves( degree 3 or higher).
Obviously, there is no curvature in the polyline of a line segment. And derivative means tangent, ie, a slope at some point in a curve.

Thank you. Didn't realise that until you pointed it out. I will try another method. Thanks
