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
" y! v; `1 P) [; A; l+ _" h) F* qNXObject nXObject2;

我返回了nXObject2;

    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)");
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;

# w. Y  G: p6 D% H6 \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
& u1 r2 Y; [5 Q" h9 [    features1[0] = offsetCurve1;
    workPart.Features.SuppressFeatures(features1);
它报错说无法将 NXOpen.sketchoffset强制转换成NXOpen.Features.OffsetCurve;
