How to use SetCurveCurveIntersectionDir function

Hi all.

I want to use ON_SetCurveCurveIntersectionDir while Curve Curve Intersection, but I don’t know how to use it. Can somebody post a simple example how to use this function.


Hi Biljana,

Why do you need to call this function?

The only place this function is used in Rhino is by our curve-curve intersector when it detects coplanar curves…

Hi Dale

I need direction of the curves at the intersection points. First I thought to use SetCurveCurveIntersectionDir but now I find the direction with EvTangent function.
