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.

Thanks

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.

Thanks
