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
' a0 C5 z8 o, ZNXObject nXObject2;
2 T6 J+ M  ]  w2 I    nXObject2 = skeTChOffsetBuilder1.Commit();
   
    NXObject[] objects1;
; D4 k$ R5 X! B. p# P- l    objects1 = sketchOffsetBuilder1.GetCommittedObjects();
我返回了nXObject2;
$ b1 z1 k$ W' n并录制了一个草图拉伸的日志 里面这么写的

1 q$ T- K* V0 i3 Y2 Z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;
. H8 e( v% O& ^
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
    features1[0] = offsetCurve1;
' T* g; S6 P; r  K: `/ t; s    workPart.Features.SuppressFeatures(features1);
它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.Features.OffsetCurve;

求高手告诉我下怎么转换
