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
/ R) Q  K; B* J3 }* p0 s3 j6 gNXObject nXObject2;
5 Y; y% ^5 [9 ?# m/ K# j2 V    nXObject2 = skeTChOffsetBuilder1.Commit();
! A: Q! l% ~0 y  Q0 H   
    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

    NXOpen.Features.SketchFeature sketchFeature1 = (NXOpen.Features.SketchFeature)workPart.Features.FindObject("SKETCH(16)");
    features1[0] = sketchFeature1;

    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;
3 ?' w: i! W2 \! M1 @: \% J/ C

NXOpen.Features.Feature[] features1 = new NXOpen.Features.Feature[1];

    workPart.Features.SuppressFeatures(features1);
' B  Y' p9 @2 }& k7 t" R. @+ g5 L; t它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.Features.OffsetCurve;
