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
) a$ M& E1 I! o# K/ ~NXObject nXObject2;
    nXObject2 = skeTChOffsetBuilder1.Commit();
7 ~, ?) k; u* X( O8 y  B( X   
    NXObject[] objects1;
! v& q6 e7 Z0 P$ u' b7 @    objects1 = sketchOffsetBuilder1.GetCommittedObjects();
9 h# b9 n. T3 K( [! m$ o我返回了nXObject2;
并录制了一个草图拉伸的日志 里面这么写的

# ^' u2 \9 o% }  m; S+ `    NXOpen.Features.SketchFeature sketchFeature1 = (NXOpen.Features.SketchFeature)workPart.Features.FindObject("SKETCH(16)");

    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；
