CurveEvaluator on drawing (.idw)

[Anonymous]

Hi,

Is there a CurveEvaluator for use in 2D drawings?

I'm trying to figure out if a quadrant point of an arc is on the arc or not.

here's what I tried so far;

                    CurveEvaluator  oCurveEval = default(CurveEvaluator);
                    oCurveEval = drawingCurve.Evaluator3D;
                    double[] oCor = new double[3];
                    double[] geussParam = new double[2];
                    double[] maxDev = new double[2];
                    double[] paramsdf = new double[2];
                    SolutionNatureEnum[] soluNatur = new SolutionNatureEnum[1];

                    returnGeomIntent = oSheet.CreateGeometryIntent(dCurve, PointIntentEnum.kCircularTopPointIntent);
                    oCor[0] = returnGeomIntent.PointOnSheet.X;
                    oCor[1] = returnGeomIntent.PointOnSheet.Y;
                    oCor[2] = 0;

                    oCurveEval.GetParamAtPoint(ref oCor, ref geussParam, ref maxDev, ref paramsdf, ref soluNatur);

Similar code with an CurveEvaluator2D gives also no results.

Thanks,
