revit二次开发API示例 Auto stamp when print view. 打印视图时自动盖章
582
2024/09/29
应用程序：AutoStamp
Revit平台：所有
Revit版本：2011.0
首次发布用于：2010.0
编程语言：C#
技能等级：中等
类别：基础
类型：外部应用
主题：打印视图时自动盖章。
摘要：此示例演示如何订阅ViewPrint事件，在事件处理程序中创建和删除TextNote元素，以及在创建失败时取消事件
相关类:
Autodesk.Revit.UI.IExternalApplication
Autodesk.Revit.DB.TextNote
Autodesk.Revit.DB.Geometry.XYZ
Autodesk.Revit.DB.Events.ViewPrintingEventArgs
Autodesk.Revit.DB.Events.ViewPrintedEventArgs
项目文件：
Application.cs
此文件包含一个类Application，该类实现IExternalApplation接口。当Revit启动时，OnStartUp方法将注册ViewPrinting、ViewPrinted事件。
Eventsactor.cs
这个文件包含一个类Eventsactor，它由两个处理程序方法组成，它们将分别订阅ViewPrinting和ViewPrinted事件；它还包含用于将相关信息转储到日志文件的其他方法。预事件处理程序将在打印开始前创建TextNote元素，并实现自动戳功能；视图打印完成后，后事件处理程序将删除在前事件处理程序中创建的元素。
功能：
该示例实现了IExternalApplication接口，并在OnStartUp方法中订阅ViewPrinting、ViewPrinted、事件；注册的事件处理程序将创建和删除TextNote元素，并在引发事件时将打印相关信息转储到日志文件。
-ControlledApplication级别的ViewPrinting和ViewPrinted事件的事件委托将被订阅以对打印操作作出反应。
-当引发ViewPrinting时，EventAgrs属性View将用作TextNote.Create方法的视图方法参数；处理程序还将保留新创建的TextNote的Id值，以便以后删除它。
-如果由于某种原因创建TextNote失败，此示例将通过将ViewPrinting EventAgrs的cancel属性设置为true来取消此视图的打印过程。
-当引发ViewPrinted时，EventArgs属性Document可用于通过方法Document.delete（ElementId）删除元素。
-方法Autodesk.Revit.DB.TextNote.Create（…）将用于创建TextNote元素。
-可以通过方法PrintSetting.PrinterName从EventAgrs属性Setting中检索打印机名称；可以通过System.Environment.UserName检索用户名。
实施：
1.将示例文件夹下提供的.addin文件复制到Revit的安装文件夹，并指定dll的完整路径。
2.启动Revit，注意ViewPrinting和ViewPrinted事件将自动注册。
3.通过UI引发打印事件：运行打印命令File\print打印视图；每个打印的视图将在视图的原始位置自动加盖打印机名称和用户名（如果AutoStamp.dll是在调试模式下构建的）；如果您在发布模式下构建AutoStamp.dll，则将打印“ABC…XYZ”以进行查看。
//注：
该示例设计为在通过Revit的UI调用打印时工作。如果从API调用内部调用打印，则可能无法正常工作，因为API命令可能会对当前文档施加编辑限制。
