How Cut Curve

Rhino Developer
1

I need to cut a Curve in a point3d.

I´m using C#.

I have a curve and I have a Point3d and I know that this Point3d belongs to the curve.

How I can cut the Point3d and the curve start with this point?

The approach i would use is to determine the parameter of the curve that corresponds to the point using ClosestPoint method. Then use the Split method with that parameter.
