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();
   
6 C9 I* i) C4 p    NXObject[] objects1;
    objects1 = sketchOffsetBuilder1.GetCommittedObjects();
我返回了nXObject2;
/ H( Y! s' a+ F并录制了一个草图拉伸的日志 里面这么写的

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；
* n0 f9 t4 x( X3 E/ E它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.features.sketchfeature;

; v' ]8 m! c# S" e$ h8 d: H% q再录一段没有草图的拉伸

    workPart.Features.SuppressFeatures(features1);
6 l4 K% \9 G& o. G3 ]6 L它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.Features.OffsetCurve;

$ R- b" N- [8 s6 |( l  R求高手告诉我下怎么转换
