# How to determine curvature radius using nx?

I need to calculate a curvature radius of this surface between 100mm x and y using nx..How can i calculate this radius using this points?

There is not enough details in the attached image

If you cannot calculate it, and to save modelling time, You can put the same image as a reference background in the design software and trace over it to draw the satisfactory curvature.

Hi,Auday

the above image is not 2d its 3d curved surface...i need to find a curvature radius for every 200x200 portion,on the surface itsself ..so i need that thing.

If it is 3D you, then you still don't have enough data to get the 3d curvature, maybe I got it wrong!
