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();
   
+ v/ V- F3 u/ n" g    NXObject[] objects1;
    objects1 = sketchOffsetBuilder1.GetCommittedObjects();
. Q" p! J) c' m' V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];
- s& B9 d9 s0 `6 c) x5 d% Y- \    NXOpen.Features.SketchFeature sketchFeature1 = (NXOpen.Features.SketchFeature)workPart.Features.FindObject("SKETCH(16)");

它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.features.sketchfeature;
