What is Revit API Events or pyRevit hooks?
Event - Is an action that can be monitored by the software. This means that we can subscribe to an event, and whenever it happens we will execute a piece of our code.
pyRevit hook is a simplified way of subscribing to Events. It allows you to simply create hooks folder, and name your python file and pyRevit knows what to do next.
Why do we need Events?
When we work with Revit API we have an ability to subscribe to Events, and execute code when they are triggered. This allows you to wait for certain actions and then execute your code when it happens. It can open a whole new world of automation in Revit.
For example, we know that Import CAD is a cursed button, and many BIM managers try very hard to make everyone Link CAD files instead of importing because they bring a lot of useless patterns, and don't have an original path associated with them… So we can subscribe to a command event of Import CAD button, and whenever it's clicked we can execute our assigned code (show a warning message in this case).
This examples is exactly what I will show you how to create by the end of this lesson. But first let's explore Revit API events a bit more.
Revit API Event Types
There are a lot of events available in Revit API, and I will try to categorize and list them here starting with Database events.
1️⃣ DataBase Events (Application )
Database events are looking for changes related to the project and application state. It will monitor when projects are being saved, opened printed, exported and similar interactions. These events can be found under Application Class and here is a list of them:
DocumentChanged - notify when a transaction is committed, undone or redone
DocumentClosing - notify when Revit is about to close a document
DocumentClosed - notify just after Revit has closed a document
DocumentCreating - notify when Revit is about to create a new document
DocumentCreated - notify when Revit has finished creating a new document
DocumentOpening - notify when Revit is about to open a document
DocumentOpened - notify after Revit has opened a document
DocumentPrinting - notify when Revit is about to print a view or ViewSet of the document
DocumentPrinted - notify just after Revit has printed a view or ViewSet of the document
DocumentReloadedLatest - notify after Revit has finished reloading a document with central model
DocumentReloadingLatest - notify when revit is about to reload latest changes from central model
DocumentSaving - notify when Revit is about to save the document
DocumentSaved - notify just after Revit has saved the document
DocumentSavingAs - notify when Revit is about to save the document with a new name
DocumentSavedAs - notify when Revit has just saved the document with a new name
DocumentSynchronizingWithCentral - notify when Revit is about to synchronize a document with the central file
DocumentSynchronizedWithCentral - notify just after Revit has synchronized a document with the central file
DocumentWorksharingEnabled - notify when a document has become workshared
ElementTypeDuplicated - notify when Revit has finished duplicating an element type.
ElementTypeDuplicating - notify when Revit is just about to duplicate an element type.
FailuresProcessing - notify when Revit is processing failures at the end of a transaction
FamilyLoadedIntoDocument - notify after Revit loaded a family into a document.
FamilyLoadingIntoDocument - notify when Revit is just about to load a family into a document.
FileExporting - notify when Revit is about to export to a file format supported by the API
FileExported - notify after Revit has exported to a file format supported by the API
FileImporting - notify when Revit is about to import a file format supported by the API
FileImported - notify after Revit has imported a file format supported by the API
LinkedResourceOpened notify immediately after Revit has finished opening a linked resource.
LinkedResourceOpening notify when Revit is just about to open a linked resource.
ProgressChanged - notify when an operation in Revit has progress bar data
ViewExported notify immediately after Revit has finished exporting a view of the document.
ViewExporting notify when Revit is just about to export a view of the document.
ViewPrinted - notify just after Revit has printed a view of the document
ViewPrinting - notify when Revit is about to print a view of the document
ViewsExportedByContext notify immediately after Revit has finished exporting one or more views of the document via an export context by CustomExporter.
ViewsExportingByContext notify when Revit is just about to export one or more views of the document via an export context by CustomExporter.
WorksharedOperationProgressChanged notify when progress has changed during Collaboration for Revit's workshared operations: open model and synchronize with central.
Then we have related to Revit UI. These are about interaction with the application or certain actions being taken. All these events are located in UIApplication Class, and here is the list:
ApplicationClosing -be notified when the Revit application is just about to be closed.
DialogBoxShowing - be notified when Revit is just about to show a dialog box or a message box.
DisplayingOptionsDialog - be notified when Revit options dialog is displaying.
DockableFrameFocusChanged - be notified when a Revit GenericDockableFrame has gained focus or lost focus in the Revit user interface.
DockableFrameVisibilityChanged - be notified when a Revit GenericDockableFrame has been shown or hidden in the Revit user interface.
FabricationPartBrowserChanged - be notified when MEP Fabrication part browser is updated.
FormulaEditing - be notified when the edit formula button has been clicked.
Idling - be notified when Revit is not in an active tool or transaction.
SelectionChanged - be notified after the selection was changed.
TransferredProjectStandards - be notified after the scope of a Transfer Project Standards operation has been finalized.
TransferringProjectStandards - be notified before the scope of an impending Transfer Project Standards operation has been finalized in the Transfer Project Standards dialog.
ViewActivated - be notified immediately after Revit has finished activating a view of a document.
ViewActivating - be notified when Revit is just about to activate a view of a document.
There are also Events under Autodesk.Revit.UI - PreviewControl for monitoring user's interaction like DragEnter, DragLeave…
3️⃣ CommandBinding Event
We can create Command Binding Events. This will allow us to monitor commands within Revit and subscribe to them. You can see a list of all commands in PostableCommand Enumeration, it has hundreds if not thosands of commands, so I won't list them here…
On top of that all these commands can be subscribed as:
BeforeExecuted- This read-only event occurs before the associated command executes. An application can react to this event but cannot make changes to documents, or affect the invocation of the command.
CanExecute - Occurs when the associated command initiates a check to determine whether the command can be executed on the command target.
Executed - This event occurs when the associated command executes and is where any overriding implementation should be performed.
💡pyRevit simplifies this step for us, but I will also show you how to manually subscribe with code, and these stages of an Event will matter.
4️⃣ IUpdater (Dynamic Model Update)
Lastly, I want to mention that there is also an IUpdater Interface. It's The interface used to create an updater capable of reacting to changes in the Revit model. It also has its hook equivalent in pyRevit doc-updater.py
Technically it's not an event, but it acts like one. It allows us to monitor changes in the project, and piggy back on the same Transaction to add our additional changes to it.
Just to give you an example how it can be used:
We can monitor changes for Windows, and whenever they change, we might want to update X,Y,Z coordinates in one of the parameters, so we can actually tag their location and it will always update as you move them.
There are endless possibilities for new functionality by using IUpdater. It's incredible useful, but I won't cover it in this lesson. It deserves a lesson of its own. Comment on the YouTube video if you want to see how to use it 😉
So how do we work with Events?
We have 2 options to subscribe to Events in Revit API.
🅰️ pyRevit Hooks - Very powerful and beginner friendly approach
🅱️ Manually Subscribe to Events - You can also write the whole code yourself to subscribe, but then it needs to be executed every time you start Revit or whenever you need it.
I will mainly focus on pyRevit hooks, but I will also show an example of doing it manually in the end.
🎯 Let's create an Event to monitor when users click on Import CAD button. And then we will give them a warning, saying that they should Link instead of importing and ask for a password, so only a select few users can import CAD files. You can apply the same concept to other buttons or other events, it's just an example I chose.
pyRevit Hooks
pyRevit provides a very simple approach to events. I will also link additional resources here that will help you understand them and see a few examples:
In a nutshell - you need to create a hooks folder in .extension folder and place your scripts for certain events. And keep in mind that naming of your scripts in that folder is very important. The name of the files will tell pyRevit what kind of event should it be subscribed to. You can see a table of all hooks in Extension Hooks.
Creating pyRevit hooks is not that complicated. It's all about creating a python file with the correct name, and writing the script that you want to execute when event gets triggered.
💡 I know it still sounds confusing, but it's not! Let me show you how to actually use it.
How to create pyRevit Hooks? (Example)
There are plenty of different hooks to choose from, but I will start with command-before-exec[<cmd-id>]. This kind of hook can subscribe to certain commands inside of Revit and trigger BEFORE it's executed.
You can see a full list of commands and how to get them in the end of this post, but I need to name it command-before-exec[ID_FILE_IMPORT].py,so it gets triggered when user click on Import CAD button.
Let's make sure our users won't import CAD to Revit Projects and only allow in Family Documents.
First of all we need to create a hook python file in a hooks folder. Make sure you name your file correctly. In my case I want to create an Event for ID_FILE_IMPORT command, so I will have to name my file command-before-exec[ID_FILE_IMPORT].py
Here is folder structure example: (.tab and lib folders are just for reference so you know where to place hooks))
💡This file in hooks folder will tell pyRevit that the script inside should subscribe to ID_FILE_IMPORT command.
And here is a simple code we are going to put inside this python hook.
Whenever a user clicks on Import CAD, it will check if Document is project or family document, and if it's a project doc, then show a warning asking to use Link CAD. Additionally, it will also prompt a TextDialog asking for a password. If they enter the right one, they will be able to import CAD inside the project. Otherwise it won't allow importing CAD, and our BIM Managers can sleep tight at night.
from pyrevit import revit, EXEC_PARAMS
from Autodesk.Revit.UI import TaskDialog
sender = __eventsender__
args = __eventargs__
doc = revit.doc
if not doc.IsFamilyDocument:
TaskDialog.Show('Big Brother is Watching!',
'Import CAD is not Allowed! Use Link CAD Instead.')
from pyrevit.forms import ask_for_string
password = 'LearnRevitAPI.com'
user_input = ask_for_string(prompt='Only users with a password can Import CAD.',
title='Import CAD Blocked')
if user_input != password:
args.Cancel = True
else:
TaskDialog.Show('Family CAD Import',
'Import CAD is Allowed in families!')
👀 Here is the Result of how it works in a Project. You will notice that once I write the correct password it allows me to Import CAD. But if I would write it wrong, it would not stop the command.
How to get PostableCommand Id?
Let's go a step back and figure out how did I know that I need to use ID_FILE_IMPORT Command name for Command Binding?
I've noticed that people get very creative when looking for the right name of the command ID. You can find it in your journals or even in the .xml file of your shortcuts.
But we can also use LookupPostableCommandId Method which comes from Autodesk.Revit.UI.RevitCommandId.
This method takes a PostableCommand Enumeration, which has a list of all possible commands. There are hundreds if not thosands of them.
Here is an example of how to use it:
from Autodesk.Revit.UI import RevitCommandId, PostableCommand
all_post_commands = PostableCommand.GetValues(PostableCommand)
for pc in all_post_commands: #type: PostableCommand
try:
rvt_com_id = RevitCommandId.LookupPostableCommandId(pc) #type: RevitCommandId
print('{} {}'.format(str(pc).ljust(45), rvt_com_id.Name))
except:
print(pc)
This will give you a list of all Postable Commands.

How to Subscribe to Events Manually?
Lastly, here is an example on how to subscribe to events manually. pyRevit takes this step from us, and makes it even nicer to manage it in a folder. But you might want to know how it's used too.
You need to do the following steps:
1️⃣ Create a functions that will be subscribed to an event. I called it import_replacement in my example
2️⃣ Get Command Id with LookupCommandId or LookupPostableCommandId
3️⃣ CreateAddInCommandBinding
4️⃣ Now you can subscribe your function to this command. Make sure you select from BeforeExecuted, CanExecute, Executed Events.
Here is an Example:
from Autodesk.Revit import UI
from Autodesk.Revit.DB import *
import clr
clr.AddReference('System')
from System import EventHandler
def import_replacement(sender, args):
TaskDialog.Show('Stop!', 'Do not import!')
uiapp = __revit__
commandId = UI.RevitCommandId.LookupCommandId("ID_FILE_IMPORT")
try:
import_binding = uiapp.CreateAddInCommandBinding(commandId)
import_binding.BeforeExecuted += EventHandler[UI.Events.ExecutedEventArgs](import_replacement)
except:
import traceback
print(traceback.format_exc())
You can use RevitPythonShell to test it. But keep in mind that this event handler will work until you restart Revit or unsubscribe from an event. To unsubscribe from the event, you can use the same code and only change += to -= like this:
import_binding.Executed -= EventHandler[UI.Events.ExecutedEventArgs](eventhandler_file_import)
Happy Coding!
Congratulations!
You've just unlocked a new achievement and you can use pyRevit Hooks and Revit API Events!
