草图偏置曲线返回的OBJECT无法用日志拉升

smalfly11

这是录的日志里草图偏置曲线里的
NXObject nXObject2;
& C2 w1 ~: |: o, `    nXObject2 = skeTChOffsetBuilder1.Commit();
- E& d+ d: Z- ]) P8 r) z% R; Q   
5 e9 D& f; q' u9 [9 T/ R0 m' w    NXObject[] objects1;
    objects1 = sketchOffsetBuilder1.GetCommittedObjects();
我返回了nXObject2;
并录制了一个草图拉伸的日志 里面这么写的
NXOpen.Features.Feature[] features1 = new NXOpen.Features.Feature[1];
    NXOpen.Features.SketchFeature sketchFeature1 = (NXOpen.Features.SketchFeature)workPart.Features.FindObject("SKETCH(16)");
    features1[0] = sketchFeature1;
/ t' r) _' q; n# @' q    Sketch sketch1 =(Sketch)workPart.Sketches.FindObject("SKETCH_00SKETCH_000");
    Line line1 = (Line)sketch1.FindObject("Curve Line4");
& {* X4 x: A: i3 c4 y4 Y/ B    Curve nullCurve = null;
# q6 `7 U" [' Y" G$ J    CurveFeatureChainRule curveFeatureChainRule1;

% f; r9 E; v4 B. t5 U( s   
    SelectionIntentRule[] rules1 = new SelectionIntentRule[1];
    rules1[0] = curveFeatureChainRule1;

    section1.AddToSection(rules1, line1, nullNXObject, nullNXObject, helpPoint1, NXOpen.Section.Mode.Create, false);
我把NXOpen.Features.SketchFeature sketchFeature1 = (NXOpen.Features.SketchFeature)workPart.Features.FindObject("SKETCH(16)");
2 [' s$ u/ o2 X: E1 _改成了NXOpen.Features.SketchFeature sketchFeature1 = (NXOpen.Features.SketchFeature)nXObject2；
- e7 {! R( O3 V( ^- r它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.features.sketchfeature;

再录一段没有草图的拉伸
NXOpen.Features.Feature[] features1 = new NXOpen.Features.Feature[1];
1 {8 V; Q. q7 l7 h0 `6 p4 E    NXOpen.Features.OffsetCurve offsetCurve1 = (NXOpen.Features.OffsetCurve)nXObject2;//在这写了nXObject2
    features1[0] = offsetCurve1;
    workPart.Features.SuppressFeatures(features1);
它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.Features.OffsetCurve;

求高手告诉我下怎么转换
