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;
- I2 E' X: @- K, P2 j8 h2 m    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];
# L& N. e- q% X' P; G3 e    NXOpen.Features.SketchFeature sketchFeature1 = (NXOpen.Features.SketchFeature)workPart.Features.FindObject("SKETCH(16)");
    features1[0] = sketchFeature1;
    Sketch sketch1 =(Sketch)workPart.Sketches.FindObject("SKETCH_00SKETCH_000");
# g6 y0 m+ a* B' \    Line line1 = (Line)sketch1.FindObject("Curve Line4");

    NXObject nullNXObject = null;
    Point3d helpPoint1 = new Point3d(-18.8530653857088, 21.736029640554, 0.0);

/ m$ A: t3 x2 w% N* @3 y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;
  h- n% I' ~4 p7 D
再录一段没有草图的拉伸
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;
+ |/ I( \5 q/ G8 ]1 X" D- M, W; V, P    workPart.Features.SuppressFeatures(features1);
它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.Features.OffsetCurve;
/ v7 p$ q& w& j
求高手告诉我下怎么转换
