Revit SDK 介绍：日志 Journal

前言

日志，还能回放，这功能太逆天了。第一次尝试失败了，搜了大牛 Jeremy Tammik 的博客，发现 Revit 居然还有这样诡异的设置才能回放，也是醉了。

项目地址

路径：Revit 2020.1 SDK\Samples\Journaling\CS\Command.cs

录制与回放

通过 AddinManager 加载生成的 dll，生成一堵墙：

效果：

从你的日志文件里面查找：

 Jrn.RibbonEvent "TabActivated:附加模块"
 Jrn.RibbonEvent "Execute external command:8c0a9e25-b7c5-421c-a1ab-702f73fa551f:AddInManager.CAddInManager"
Jrn.Data "APIStringStringMapJournalData"  _
        , 4, "End Point", "(100,0,0)" _
        , "Level Id", "311", "Start Point" _
        , "(0,0,0)", "Wall Type Name", "Cavity wall_sliders"

这个就是关键，不过我自己尝试重播日志，失败了。

如何才能成功？
下面这段话最重要的就是，把 journal，addin，插件dll放在同一个目录下面。这样就可以正常回放了。

However, several people had problems getting the Journaling sample to run in Revit 2012. This is due to changes in the add-in loading behaviour introduced in the recent releases of Revit in connection with the shift from INI files to the add-in manifest.

Here is the quick summary of the solution, which is utterly simple but
pretty hard to discover on your own:

To run this sample, make sure that the journal file, the add-in
manifest (.addin) and the add-in assembly (.dll) are all in the same
folder, otherwise it definitely will not work. This is by design, to
reduce the impact during regression testing: in this way, only the
required add-ins in the journal folder will be registered and loaded
by Revit.

This ties in very well with my current tendency to copy all add-in
assemblies into the Revit add-in folder, where the add-in manifests
have to be placed in order for Revit to find them. As I mentioned
discussing the add-in wizard updates, this has the significant
advantage of obviating the need to specify the full assembly path in
the add-in manifest.

代码逻辑

关键点在于：

public void Run()
{
     
   // 根据是否有日志数据来决定用何种方式创建墙
   if (m_canReadData)      // 如果有日志数据
   {
     
      ReadJournalData();  // 读取日志数据
      CreateWall();       // 创建墙
   }
   else                    // 如果没有日志数据
   {
     
      if (!DisplayUI())   // 显示UI
      {
     
         return;         // 如果用点了取消，直接退出
      }

      CreateWall();       // 创建墙
      WriteJournalData(); // 写入日志
   }
}
