Try this: Query ICurve_DG from your IBSplineCurve_DG: ICurve_DG curve = theBsplineCurve.As<ICurve_DG>(); Parameters for your intersection points can be obtained with ICurve_DG.GetNearestPoint(PointDg point, out PointDg pointNearest). It returns the parameter. So, you will get paramMin, paramMax. Do ...
