Help: Extracting curvatures from GeometricAnalysis::CurveCurvatureAnalysis

I can display a curve analysis using GeometricAnalysis::CurveCurvatureAnalysis. I would like to extract the curvature values at sampled points. What is the API for that. Also I can show the inflection points on the curve. But how to get the coordinates of those points thru program?

For curvature, the easiest is the SNAP function

 

myCurve.Curvature

 

Other options are:

 

NXOpen.UF.UFModl.AskCurveProps

NXOpen.UF.UFEval.Evaluate

 

The first of these gives you curvature directly; the second one gives you derivatives, from which you can calculate curvature.

 

For inflexions:

 

NXOpen.UF.UFCurve.AskCurveInflections

Thanks for the reply. I am looking for a way to directly extract data from Analysis. To use the functions you mentioned, I need to sample the cruve when I change my curve.

So, No one has better way to extract the curvature in an associative way?
