DocumentExtensions.GetTakeoff 

DocumentTakeoff docTakeoff =Autodesk.Navisworks.Api.Application.MainDocument.Takeoff as DocumentTakeoff;DocumentTakeoff docTakeoff2 =Autodesk.Navisworks.Api.Application.MainDocument.GetTakeoff();

注：下面有关键字 table 都是数据库里的表。
DocumentExtensions类的地方扩展到文档类的DocumentTakeoff文档部件类。DocumentTakeoff提供对与起飞相关的各种文档部分。ItemGroupTable配置信息ItemGorupTable。ItemTable配置信息ItemTable。ObjectResourceTable配置信息ObjectResourceTable。ObjectStepTable配置信息ObjectStepTable。ObjectTable配置信息ObjectTable。ResourceGroupTable配置信息ResourceGroupTable。ResourceTable配置信息ResourceTable。StepResourceTable配置信息StepResourceTable。StepTable配置信息StepTable。TakeoffTable为所有表共有的特征共同的基类。TakeoffTableSelection表示在一个表中选择。TakeoffColumnDefinition起飞表中的固定列的定义。TakeoffProjectSettings Access项目设置。TakeoffSelection切入点每个表的选择。TakeoffSelectionChangeEventArgs用于TakeoffSelection Changed事件通过哪些表被修改。TakeoffSheetIds访问表编号。TakeoffVariable代表一个变量。TakeoffVariableCollection代表配置列的行数据。TakeoffVariableDefinition起飞表变量列的定义。的配置列定义TakeoffVariableDefinitionCollection集合
