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;
    nXObject2 = skeTChOffsetBuilder1.Commit();
   
    NXObject[] objects1;
    objects1 = sketchOffsetBuilder1.GetCommittedObjects();
& s. `* q0 g( v; J8 Q: w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;
    Sketch sketch1 =(Sketch)workPart.Sketches.FindObject("SKETCH_00SKETCH_000");
$ t( `3 H8 ]  o3 l    Line line1 = (Line)sketch1.FindObject("Curve Line4");
    Curve nullCurve = null;
/ p* |+ w7 L+ T/ K    CurveFeatureChainRule curveFeatureChainRule1;
    curveFeatureChainRule1 = workPart.ScRuleFactory.CreateRuleCurveFeatureChain(features1, line1, nullCurve, false, 0.00095);

    section1.AddToSection(rules1, line1, nullNXObject, nullNXObject, helpPoint1, NXOpen.Section.Mode.Create, false);
  L' E0 m, [! z1 h5 V0 H, u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；
它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.features.sketchfeature;

" J) [: v0 G* c1 |再录一段没有草图的拉伸

    NXOpen.Features.OffsetCurve offsetCurve1 = (NXOpen.Features.OffsetCurve)nXObject2;//在这写了nXObject2
    features1[0] = offsetCurve1;
- g4 }1 y7 G! R6 A( q# D1 k5 L    workPart.Features.SuppressFeatures(features1);
它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.Features.OffsetCurve;
