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;
6 ^1 K3 z) A6 h, Z4 p    nXObject2 = skeTChOffsetBuilder1.Commit();
   
4 L- L' u3 _9 H    NXObject[] objects1;
2 b" I' Y& u( y    objects1 = sketchOffsetBuilder1.GetCommittedObjects();
我返回了nXObject2;
" m" T4 t" O- w并录制了一个草图拉伸的日志 里面这么写的

7 J# _$ V+ K: ]2 \: a8 v7 D9 x我把NXOpen.Features.SketchFeature sketchFeature1 = (NXOpen.Features.SketchFeature)workPart.Features.FindObject("SKETCH(16)");
* {" y9 n/ ]+ f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;
* U7 ^0 ~! B2 l$ G! e0 `- y* ^
  f% p& u" Z( r: @* [2 l再录一段没有草图的拉伸
NXOpen.Features.Feature[] features1 = new NXOpen.Features.Feature[1];
    NXOpen.Features.OffsetCurve offsetCurve1 = (NXOpen.Features.OffsetCurve)nXObject2;//在这写了nXObject2
+ b( n7 f( @7 w; {& S- L    features1[0] = offsetCurve1;
% K. K& M+ |+ H    workPart.Features.SuppressFeatures(features1);
它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.Features.OffsetCurve;

* P9 u$ m5 A& J求高手告诉我下怎么转换
