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
( T+ a5 P$ B" E5 }% ]NXObject nXObject2;
5 ~7 [) X4 f3 J: h    nXObject2 = skeTChOffsetBuilder1.Commit();
   
    NXObject[] objects1;
    objects1 = sketchOffsetBuilder1.GetCommittedObjects();
我返回了nXObject2;
* i4 A# l3 C% y! I并录制了一个草图拉伸的日志 里面这么写的

    Sketch sketch1 =(Sketch)workPart.Sketches.FindObject("SKETCH_00SKETCH_000");
    Line line1 = (Line)sketch1.FindObject("Curve Line4");
    Curve nullCurve = null;

    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)");
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;
- `2 p" m( w' p+ z& B" b# h, H& u

6 G3 N, f0 P4 n3 F    NXOpen.Features.OffsetCurve offsetCurve1 = (NXOpen.Features.OffsetCurve)nXObject2;//在这写了nXObject2
    features1[0] = offsetCurve1;
    workPart.Features.SuppressFeatures(features1);
/ l, ?' i$ P8 y) e7 K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
