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();
, o6 y; ]" z! A5 d+ I) N   
    NXObject[] objects1;
0 K, [7 b4 I* |6 M: K/ b' C1 o    objects1 = sketchOffsetBuilder1.GetCommittedObjects();
我返回了nXObject2;
# Y' u0 [4 p3 E, S) ~9 F. R; T  x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)");
3 M' y) a6 Z* {$ N7 `! U3 W) @% M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;

3 J5 W8 b; Q# _( }  {# a2 U, ?再录一段没有草图的拉伸
