Revit SDK 介绍：AutoStamp 自动水印 AutoUpdate 自动更新 CancelSave

前言

这三个例子都是通过注册事件来完成相应的工作，内容比较简单。

事件参考博客：Revit API：Events 事件总览

AutoStamp 自动水印

在这里插入图片描述
使用到的事件：

application.ControlledApplication.ViewPrinting
application.ControlledApplication.ViewPrinted

注册事件：

public class Application : IExternalApplication{EventsReactor m_eventsReactor;public Autodesk.Revit.UI.Result OnStartup(UIControlledApplication application){// Register related eventsm_eventsReactor = new EventsReactor();application.ControlledApplication.ViewPrinting += new EventHandler<Autodesk.Revit.DB.Events.ViewPrintingEventArgs>(m_eventsReactor.AppViewPrinting);application.ControlledApplication.ViewPrinted += new EventHandler<Autodesk.Revit.DB.Events.ViewPrintedEventArgs>(m_eventsReactor.AppViewPrinted);return Autodesk.Revit.UI.Result.Succeeded;}public Autodesk.Revit.UI.Result OnShutdown(UIControlledApplication application){application.ControlledApplication.ViewPrinting -= new EventHandler<Autodesk.Revit.DB.Events.ViewPrintingEventArgs>(m_eventsReactor.AppViewPrinting);application.ControlledApplication.ViewPrinted -= new EventHandler<Autodesk.Revit.DB.Events.ViewPrintedEventArgs>(m_eventsReactor.AppViewPrinted);return Autodesk.Revit.UI.Result.Succeeded;}
}

事件处理：

// AppViewPrinting
TextNoteOptions options = new TextNoteOptions();
options.HorizontalAlignment = HorizontalTextAlignment.Center;
options.TypeId = e.Document.GetDefaultElementTypeId(ElementTypeGroup.TextNoteType);
TextNote newTextNote = TextNote.Create(e.Document, e.View.Id, XYZ.Zero, strText, options);// AppViewPrinted
e.Document.Delete(m_newTextNoteId);

AutoUpdate 自动更新

在这里插入图片描述

这个例子仅仅是更新了地址信息：

注册文件打开完成事件
application.ControlledApplication.DocumentOpened
事件处理函数
在文件上加入地址信息
doc.ProjectInformation.Address = “United States - Massachusetts - Waltham - 610 Lincoln St”;
