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
( \8 F6 i* }6 v$ VNXObject nXObject2;
    nXObject2 = skeTChOffsetBuilder1.Commit();
   
) N5 v# }% E- C. Y  q5 q    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
, y, y% O/ f4 J% DNXOpen.Features.Feature[] features1 = new NXOpen.Features.Feature[1];
    NXOpen.Features.SketchFeature sketchFeature1 = (NXOpen.Features.SketchFeature)workPart.Features.FindObject("SKETCH(16)");
6 p: s! \: `. t6 ^' b: n    features1[0] = sketchFeature1;
    Sketch sketch1 =(Sketch)workPart.Sketches.FindObject("SKETCH_00SKETCH_000");
    Line line1 = (Line)sketch1.FindObject("Curve Line4");
    Curve nullCurve = null;
% C  m5 T6 v2 Z* q' O5 L    CurveFeatureChainRule curveFeatureChainRule1;
    curveFeatureChainRule1 = workPart.ScRuleFactory.CreateRuleCurveFeatureChain(features1, line1, nullCurve, false, 0.00095);
& b6 l) E% S+ O7 n$ v. h   
    section1.AllowSelfIntersection(true);
   
    SelectionIntentRule[] rules1 = new SelectionIntentRule[1];
    rules1[0] = curveFeatureChainRule1;

9 i$ H2 x8 o' ~0 o0 U2 x* H    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)");
. E" ^0 X4 g; \3 W7 A. Y9 W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;

再录一段没有草图的拉伸
3 C: _+ m' o" Q NXOpen.Features.Feature[] features1 = new NXOpen.Features.Feature[1];
    NXOpen.Features.OffsetCurve offsetCurve1 = (NXOpen.Features.OffsetCurve)nXObject2;//在这写了nXObject2
    features1[0] = offsetCurve1;
' M3 A3 Z- ~$ X  N    workPart.Features.SuppressFeatures(features1);
1 B- ^0 c9 l, K" U9 F它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.Features.OffsetCurve;
+ p) l0 e- A9 o  t: z
求高手告诉我下怎么转换
