Remarks

Interior knots occur after the first set of 0s and before the last set of 1s in the knot array. If the knot array is [ 0 0 0 0 0.279240779943874 0.55 0.720759220056126 1 1 1 1 ], then the interior knots are 0.279240779943874, 0.55, and 0.720759220056126.

Before calling this method, call ISplineParamData::GetKnotPoints and ISplineParamData::KnotPointsCount to help specify Index and the new knot value.

After calling this method, you must call IModelDoc2::ForceRebuild3 to update the sketch.
