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();
   
: f0 b) w/ O( w3 d( }/ t    NXObject[] objects1;
    objects1 = sketchOffsetBuilder1.GetCommittedObjects();
2 {5 l  g2 |* v( F# k我返回了nXObject2;
并录制了一个草图拉伸的日志 里面这么写的

$ Y# K& B' z4 F; p8 S+ 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

    workPart.Features.SuppressFeatures(features1);
它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.Features.OffsetCurve;
