Adding "richness" to a topography curve / Replace points in a list

by Daniel Domenech Muñoz

I think i am posting to much in the last times.... but everything i try to do, there is always something that stop me. 

The thing now is that I have a lot of topographic curves of a city, but they are general and has no detail and I am doing some schemes like in the photo attached. So i want to move randomly some control points and then replace them in the same order and position to build the new curve... But i dont know how to do the last part, replacing and rebuild. 

Any idea?

Best regards,

Daniel

    The problem with using the existing control-points is that you may not get any randomization if the curve doesn't contain any cp's along a certain stretch. You can divide the curve into equal segments to ensure the randomness is equally spread along the curve.

    I attached two approaches, one which randomized points along the curve in the XY plane, and the other which randomized points along the curve along the local perpendicular vector.
