Intersection of two NURBS curves

Recommended Posts

I need to find the intersection of a set of NURBS curves, basically obtained from the "Contour" tool from a mesh surface. 

By hand, I can select the "Analyze" tool and then click on the two curves and get a 3D Locus on the intersection.

How can I obtain the same result using a script?

I tried to select the two nurbs and then calling the tool, but obviously "Analyze" wait for the clicks...


There is a way to automate this?


Thank you

Because NURBS curves can intersect at from zero to an infinite number of points, I don’t think VectorScript is equipped to automate this.

Thank you. 
I believe there is some algorithm that do this calculus, because the “Analyse” tool work.
