各位大侠，帮忙看下这段代码有什么问题，开始几次可以实现功能，多次调用之后，UG就会很卡，紧接着UG就会停止工作，调试显示错误为：执行引擎异常。：
NXOpen.Features.AdmResizeFace nullAdmResizeFace = null;
            NXOpen.Features.AdmResizeFaceBuilder theAdmResizeFaceBuilder;
            theAdmResizeFaceBuilder = workPart.Features.CreateAdmResizeFaceBuilder(nullAdmResizeFace);

            Face[] faces = new Face[1];
            faces[0] = face;
            FaceDumbRule faceDumbRule1;
            faceDumbRule1 = workPart.ScRuleFactory.CreateRuleFaceDumb(faces);
            SelectionIntentRule[] rules1 = new SelectionIntentRule[1];
            rules1[0] = faceDumbRule1;
            theAdmResizeFaceBuilder.FaceToResize.FaceCollector.ReplaceRules(rules1, false);

            theAdmResizeFaceBuilder.Diameter.RightHandSide = NewDiamter.ToString();
            theAdmResizeFaceBuilder.Commit();
            Expression expression1 = theAdmResizeFaceBuilder.Diameter;
            faceDumbRule1.Dispose();
            theAdmResizeFaceBuilder.Destroy();

由于以前的函数求值超时,函数求值被禁用。必须继续执行才能重新启用函数求值

你就这一段代码吗？
其他的代码会不会有问题
这是你录制的代码吧，你的face选择都是同一个？

这是子函数中的代码，是在录制“调整面大小”操作代码的基础上修改得到的。完整代码如下：

如果我模型中有一个孔，我调用该dll文件两到三次以后就会出现异常。或者模型中有好几个孔，可能前几个能处理，到了一定数量以后UG就死掉了。

估计那个地方要释放内存

这个需要调试的

Java 我不怎么用，你自己把代码一段段的调试看看

另外你干嘛要用同步建模的功能

直接使用偏置面不是更好

偏置面我没接触过，我还要用同步建模来实现孔的移动、删除等操作。

具体这个我还真没怎么研究过

不过我建议你换成偏置面，然后试试看到底是那里有问题

偏置面功能很简单，在插入 --修剪与偏置 -- 偏置面

我想实现对模型中的圆柱面的半径进行放大缩小，模型是被移除参数的。谢谢！
