标题: 求高手：为什么我的.net程序为什么不能延展body的面呢
下面的程序，我用单个曲面测试通过，但是用简单body比如block的一个面和边，却出现这样的错：

Target  / Tool must contain only exterior edges。

程序如下
            Face face = (Face)Session.GetSession().Parts.Work.FindObject("HANDLE R-2295");//为了方便，加了高亮测试
            Edge edge = (Edge)Session.GetSession().Parts.Work.FindObject("HANDLE R-2095");
            face.Highlight();
            edge.Highlight();
            TrimExtend feature = null;
            TrimExtendBuilder theBuilder = Session.GetSession().Parts.Work.Features.CreateTrimExtendBuilder(feature);
            theBuilder.ExtendNewFace = false;
            theBuilder.Type = TrimExtendBuilder.CreationTypes.ByDistance;
            theBuilder.ExtensionMethod = TrimExtendBuilder.ExtensionMethods.NaturalTangent;
            Expression exp = theBuilder.TargetExtendDistance;
            exp.RightHandSide = "10";
            FaceDumbRule theRule = Session.GetSession().Parts.Work.ScRuleFactory.CreateRuleFaceDumb( new Face[] { face });
            theBuilder.TargetCollector.ReplaceRules(new SelectionIntentRule[] { theRule },false);
            EdgeDumbRule theRule2 = Session.GetSession().Parts.Work.ScRuleFactory.CreateRuleEdgeDumb(new Edge[] { edge });
            theBuilder.TargetCollector.ReplaceRules(new SelectionIntentRule[] { theRule2 }, false );
            //theBuilder.TargetReversed = true;
            theBuilder.Commit();
            face.Unhighlight();
            edge.Unhighlight();
