what is problem with this code?for example
DrawingCurvesEnumerator drawingCurves = drawingView.DrawingCurves;
DrawingCurve drawingCurve1 = null;
DrawingCurve drawingCurve2 = null;
DrawingCurve drawingCurve3 = null;
DrawingCurve drawingCurve4 = null;
drawingCurve1 = drawingCurves[1];
drawingCurve2= drawingCurves[2];
drawingCurve3 = drawingCurves[3];
drawingCurve4 = drawingCurves[4];
GeometryIntent firstGI = sheet.CreateGeometryIntent(drawingCurve1);
GeometryIntent SecondGI = sheet.CreateGeometryIntent(drawingCurve2);
GeneralDimensions generalDimensions = sheet.DrawingDimensions.GeneralDimensions;
Point2d point2D1 = inventorApp.TransientGeometry.CreatePoint2d(15,15);
LinearGeneralDimension linearGeneralDimension = generalDimensions.AddLinear(point2D1, firstGI, SecondGI,DimensionTypeEnum.kAlignedDimensionType);
linearGeneralDimension.CenterText();
