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();
   
2 u1 s: R' ^* d    NXObject[] objects1;
    objects1 = sketchOffsetBuilder1.GetCommittedObjects();
我返回了nXObject2;
1 E5 }+ P* X% s; O* c7 s并录制了一个草图拉伸的日志 里面这么写的

+ \4 ~) B: i& n9 C    section1.AddToSection(rules1, line1, nullNXObject, nullNXObject, helpPoint1, NXOpen.Section.Mode.Create, false);
我把NXOpen.Features.SketchFeature sketchFeature1 = (NXOpen.Features.SketchFeature)workPart.Features.FindObject("SKETCH(16)");
- l: ^* G+ @4 O3 d- d6 V8 u* j改成了NXOpen.Features.SketchFeature sketchFeature1 = (NXOpen.Features.SketchFeature)nXObject2；
* k* G4 W; L; P2 O: Y4 h9 b它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.features.sketchfeature;

再录一段没有草图的拉伸
NXOpen.Features.Feature[] features1 = new NXOpen.Features.Feature[1];
/ X5 Z7 a+ }$ F    NXOpen.Features.OffsetCurve offsetCurve1 = (NXOpen.Features.OffsetCurve)nXObject2;//在这写了nXObject2
; x3 r/ l# D# o/ R' C) D4 q    features1[0] = offsetCurve1;
0 o2 L5 E( s& c7 ^( X5 G8 m    workPart.Features.SuppressFeatures(features1);
它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.Features.OffsetCurve;
$ i! c: Y; [& `* u0 }/ ]# ]
