应用程序：DoorSwing
Revit 平台：建筑
Revit 版本：2011.0
首次发布时间：2009.0
编程语言：C#
技能水平：中等
类别：房间/空间
类型：ExternalCommand、ExternalApplication
主题：管理门的开启和与门有关的房间。
摘要：本示例将演示如何创建和维护门开启参数、内部门参数、从/到房间参数，以及如何对这些参数进行编排。还提供了自定义国家标准的功能

项目文件：
Command.cs
该文件包括三个类InitializeCommand、UpdateParamsCommand和UpdateGeometryCommand。它们都实现了接口IExternalCommand。
ExternalApplication.cs
该文件包括一个类ExternalApplication，该类实现了接口IExternalApplication。该类将创建一个自定义的Ribbon面板，其中包含三个按钮，用于调用Command.cs文件中定义的三个外部命令。该类还订阅了一些应用级别事件，以更新门参数。这可以确保在保存、另存为等操作时文档是正确的。
DoorSwingData.cs
该文件包括一个类DoorSwingData，该类准备所需的数据并更新门开启、内部/外部门和从/到房间信息。
DoorFamily.cs
该文件包括一个类DoorFamily，该类维护每个门族的族名称、族几何和门开启表达式信息。它还根据每个门族的几何和国家标准自定义门开启表达式。
DoorFamilyGeometry.cs
该文件包括一个类DoorGeometry，该类用于将Revit几何数据转换为适合GDI的格式。
DoorSharedParameters.cs
该文件包括一个静态类DoorSharedParameters，该类用于向门添加三个共享参数，并将其命名为BasalOpening、InstanceOpening和Internal Door。
InitializeForm.cs
该文件包括一个窗体类InitializeForm，它包括一个DataGridView，用于显示当前Revit项目中存在的所有门族，还有一个pictureBox，用于显示门族的几何图形。用户可以根据每个门族的几何和国家标准在这里自定义门开启表达式。
DoorSwingResource.resx
一个资源文件，包含一些用于识别门开启的字符串。
描述：
对于门的开启功能，用户可以调用外部命令“自定义门开启表达式”，添加所需的共享参数，并根据自己国家的标准和每个门族的几何形状自定义门开启表达式。当门被翻转或镜像时，用户可以调用外部命令“更新门属性”以更新参数值。这些参数的计划将从Revit UI中完成。
对于与门相关的房间功能，从Revit UI中用户可以在两个分别的计划表中调度内部和外部门的“到房间”和“从房间”信息，并且可以在计划表中更改门的方向。然后，用户将使用“更新门几何图形”命令，以在计划表中更改门的方向后更新门的几何形状。当在视图中翻转或镜像门时，用户可以调用外部命令“更新门属性”以更新“到房间”和“从房间”信息。
在关闭、保存或另存为项目文件时，参数更新过程也将被触发。
实施：
1. 准备Revit项目。
打开或新建一个Revit项目，并确保所有需要的房间都已放置。如果您的项目文件中有任何未定义房间的封闭墙回路，则示例将显示对话框，询问您是否将界定这些区域的门视为外部门。
样本项目文件DoorSwing.rvt可在样本文件夹中找到。
2. 自定义门开启表达式。
单击“自定义门开启表达式”命令（菜单项或Ribbon按钮）根据家族的几何形状和您的国家标准自定义每个门家族的开启表达式。这是该样本的第一个命令。如果列表中没有符合您国家标准的表达式，可以打开源代码项目并在以下3个区域中进行修改：
a. 编辑项目资源文件。
b. 编辑DoorSwingData.cs中的DoorSwingData静态构造函数。从资源文件中将更多门开启表达式添加到OpeningTypes列表中。
c. 编辑DoorSwingData.cs中的UpdateOpeningFeatureOfOneDoor函数。在“if(switchesOpeningValueFlag){...}”语句中添加更多else if来处理添加的门开启表达式。
希望创建本地化版本的用户可以按照上述步骤2.a进行操作。
3. 计划参数。
从Revit UI创建门计划。您可以安排“开口”、“内部门”参数和“从房间”/“到房间”的“房间编号”或任何其他需要的参数。
a. 创建内部门计划。
Revit按钮：视图选项卡->创建面板->计划/数量按钮；
类别：门；名称：内部门计划。
添加需要计划的参数。
• 添加现有参数：标记、内部门、InstanceOpening、FromRoom:Number、ToRoom:Number；
• 添加计算值：名称：Opening，选择：公式，学科：普通，类型：文本，公式：InstanceOpening。
• 将Opening参数移至InstanceOpening参数之前。
修改计划的外观，包括可见性、排序等。
• 如果需要，则隐藏内部门和InstanceOpening列：右键单击“内部门”列，然后单击“隐藏列”菜单；右键单击“InstanceOpening”列，然后单击“隐藏列”菜单；
• 按门的标记值排序项目：在计划中任何位置右键单击，然后单击“查看属性”菜单；在属性对话框中的“排序/分组”项目；按标记排序。
• 按内部门过滤：在属性对话框中的“过滤器”项目；按Internal Door等于Yes过滤。
b. 创建外部门计划。
按照创建内部门计划的相同步骤操作，只需进行Filter设置。按Internal Door等于No筛选。
4. 当翻转/镜像门时，更新门参数。
翻转/镜像任何门，然后单击“更新门属性”命令（菜单项或Ribbon按钮）。该命令将根据门的几何形状更新门参数。
5. 在计划中更改门的方向时，更新门的几何形状。
您甚至可以从计划中更改“从房间”/“到房间”的房间编号。之后，单击“更新门几何”命令将根据您在计划中所做的更改更改门的几何形状。
