调用方法：

 Transaction tran = new Transaction(doc, "测试");
                    var failure = new BeeFaceFailureHandler();
                    BeeFaceFailureHandler.SetFailedHandlerBeforeTransaction(failure, tran);
                    tran.Start();
                    //-------
                    tran.Commit();

 

下面讲一下之前碰到的创建楼板的一个错误：边界边缘线彼此相交.边界等高线不可扭曲

解决方案：

1. 板的”结构“属性不要勾选，或者

2. 板的”启用分析模型“不要勾选

对应的，我们可以再创建floor之后，马上调用下面的任何一段代码：

1.floor.get_Parameter(BuiltInParameter.STRUCTURAL_ANALYTICAL_MODEL).Set(0);

2.floor.get_Parameter(BuiltInParameter.FLOOR_PARAM_IS_STRUCTURAL).Set(0);

如果不需要分析模型，请使用方法2,如果既不需要分析模型又不需要钢筋，请使用方法1.
