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
: v9 n4 ?0 g2 N5 F" LNXObject nXObject2;
    nXObject2 = skeTChOffsetBuilder1.Commit();
   
    NXObject[] objects1;
' }% n+ e* x/ f2 h. k    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

    section1.AddToSection(rules1, line1, nullNXObject, nullNXObject, helpPoint1, NXOpen.Section.Mode.Create, false);
: w) @: @  W3 l9 a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；
5 T5 M( L# U( Y: T# ^! O  I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
NXOpen.Features.Feature[] features1 = new NXOpen.Features.Feature[1];
