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
" L8 R/ h+ I, g3 lNXObject nXObject2;
    nXObject2 = skeTChOffsetBuilder1.Commit();
   
# y! u' S% D! A+ O5 Z    NXObject[] objects1;
    objects1 = sketchOffsetBuilder1.GetCommittedObjects();
) Q) f7 t# k& Z: w我返回了nXObject2;
4 L: v& X; _# q. |+ Y  ?% T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)");
+ @% k( s9 ~( F3 T) T    features1[0] = sketchFeature1;
$ m+ P7 ^% W" v    Sketch sketch1 =(Sketch)workPart.Sketches.FindObject("SKETCH_00SKETCH_000");
    Line line1 = (Line)sketch1.FindObject("Curve Line4");

    CurveFeatureChainRule curveFeatureChainRule1;
$ e6 n) l* R4 T+ Q8 s. k    curveFeatureChainRule1 = workPart.ScRuleFactory.CreateRuleCurveFeatureChain(features1, line1, nullCurve, false, 0.00095);
   
    section1.AllowSelfIntersection(true);

    Point3d helpPoint1 = new Point3d(-18.8530653857088, 21.736029640554, 0.0);
7 d7 S% H8 G) K9 n( r' C; M    section1.AddToSection(rules1, line1, nullNXObject, nullNXObject, helpPoint1, NXOpen.Section.Mode.Create, false);
$ k, k- \9 _4 ]我把NXOpen.Features.SketchFeature sketchFeature1 = (NXOpen.Features.SketchFeature)workPart.Features.FindObject("SKETCH(16)");
改成了NXOpen.Features.SketchFeature sketchFeature1 = (NXOpen.Features.SketchFeature)nXObject2；
* t1 T+ A8 u3 W* e3 Z它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.features.sketchfeature;
+ |/ a5 J0 ^  L2 R' ?
再录一段没有草图的拉伸
NXOpen.Features.Feature[] features1 = new NXOpen.Features.Feature[1];
& ~( l9 @  _) P6 t    NXOpen.Features.OffsetCurve offsetCurve1 = (NXOpen.Features.OffsetCurve)nXObject2;//在这写了nXObject2
    features1[0] = offsetCurve1;
: ?2 `, [5 d* r    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
